The server-side ownership of the palette is a stumbling block for
many users, so let's fix it.
This commit allows the client to pass its configured palette to
the server when it connects, and when the config is changed.
That palette takes precedence over the palette from the server config.
However, if the remote application uses any escape sequences that
redefine the color palette, the color palette that was active at
that point in time is forked and use as the basis, and will remain
the active palette until the palette is reset via escape sequences.

This commit teaches the config about SerialDomains, and the mux
layer about constructing a SerialDomain, then changes the GUI
layer to use those pieces to set up `wezterm serial`.
A new `serial_ports` config is added, and the GUI layer knows how
to apply it to the set of domains in the mux.
The result of this is that you can now define a domain for each
serial port and spawn a serial connection into a new tab or window
in your running wezterm gui instance.
This got broken around the time we started to re-exec the mux
server. Since the fd was CLOEXEC we'd essentially unlock and
ignore the lock at the point we'd re-exec.
This commit allows the fd to remain open and locked across
the exec, and causes the exec'd process to set CLOEXEC by
explicitly telling it about the log fd, so that shells and
things spawned by the mux don't hold the lock.
Work harder to notice and handle the PaneRemoved notification
more centrally, which allows removing some earlier workarounds.
Now when we receive PaneRemoved, we take the opportunity to handle
missing mapping or stale mapping between local and remote ids and
perform a resync before continuing to handle the PaneRemoved message.
Doing it this way means that we don't need to second guess the timing
of notification or the resync, so we end up with the correct sequence
of notifications, and the result is the correct size of the splits
because the local and remote aren't independently managing the
the pane removal with conflicting ideas of the new size.

Three issues:
* The initial connect would leave the dpi assigned to 0, resulting
in incorrect scaling when using imgcat until the window was resized
and the correct dpi was passed up.
* On resize, we'd only compare the row/col count and not notice changes
in pixel dimensions/dpi
* On the server side, when processing a resize and recomputing
the tab size, we would omit the pixel dimensions and leave
the resulting tabs and panes with 0 dimensions, breaking imgcat
because it thought the window was 0x0.

This fixes a surprising interaction between copy mode and the

Given an assignment like this:
```
{
key = "b",
mods = "ALT",
action = wezterm.action.SplitPane {
direction = 'Right',
command = {
label = 'Bash Right',
args = {'/usr/bin/bash' }
}
}
}
```
we should show the label from the command in the palette.
That's what this commit enables.
If there is no label, but the arguments are set, then the
arguments will be shown instead.

This commit causes the mux to generate a PaneFocused notification

The mux server will forward that as a unilateral PDU to connected
clients.
The clientpane implementation will handle that by applying the
same state to the local mux.

Weird behavior from macos; the command line:
`wezterm start vim hello`
would result in macos requesting `vim` and `hello` be opened
as "documents" which would route each of those to the .command
script handling flow and spawn a window for each; running:
`vim ; exit` in one
`hello ; exit` in another
in addition to the normal handling of that command line.
This commit resolves this by igoring document opening
requests until after the application is fully launched.
I tested this by trying to open a .command script with
this new build and verified that that continued to work.

This one was a bit weird because something appeared to be a bit
non-deterministic. With this config:
```lua
local wezterm = require 'wezterm'
return {
window_frame = {
border_left_width = '1cell',
border_right_width = '1cell',
border_bottom_height = '0.5cell',
border_top_height = '0.5cell',
border_left_color = '#444',
border_right_color = '#444',
border_bottom_color = '#444',
border_top_color = '#444',
},
window_padding = {
left = '1.5cell',
right = '1.5cell',
top = '0.5cell',
bottom = '0.5cell',
},
}
```
starting wezterm could result in a terminal that reported either 23 or
24 lines. I got 24 when running the build from da7e29df but usually
23 when running a build out of my repo.
Looking closely, the issue is that the initial window size didn't
account for the configured border size, and that we'd subsequently
fix that up when we later do a resize fixup after creating the window.
This commit refactors the window border logic so that it can be
used prior to having fully constructed the terminal window and then
uses that to fixup the initial computed dimensions.
I also noticed with this config that increasing the font size
with CTRL-+ could also result in an inconsistency between the displayed
terminal size and the pty size we set in the kernel: it was missing
the border adjustment as well, so I added it in there.

Really, this is adjusting the logical line breaking behavior, or the
lack thereof.
The situation is this: conpty can decided to reinterpret and flush
large sections of its buffer as a continuous stream of unbroken
characters with no breaks when it repaints the full screen.
When we receive such an update, we see it as one long logical line,
and when we subsequently select multiple lines we can run into the
maximum logical line length and insert invalid synthetic line breaks
into the data that we send to the clipboard.
This commit adjusts the wrapping logic at the time that we receive
the text so that we don't tag the line as a logical line continuation
if:
* The alt screen is active. Full screen apps will re-render on resize
anyway, and we don't reflow long lines on resize either for the same
reasons
* If we are talking to ConPTY:
* If the last character in the line is not alphanumeric or
punctuation (in other words: it doesn't look plausibly like
text that should be a line continuation).

There were two issues in handling this:
* We expected there to be `;payload` in the first transmission packet,
but there wasn't one, so we ignored it as ill-formed.
* The standard base64 decoder in the rust ecosystem is super strict
and rejects the "sloppy" python base64 encoder output that isn't
strictly conformant with the RFC. We need to jump through some
hoops to get it to relax and accept the input.

Continuing from the previous commit, this shifts:
* In-memory data -> temporary file
* Image decoding -> background thread
The background thread asynchronously decodes frames and
sends them to the render thread via a bounded channel.
While decoding frames, it writes them, uncompressed, to
a scratch file so that when the animation loops, it is
a very cheap operation to rewind and pull that data
from the file, without having to burn CPU to re-decode
the data from the start.
Memory usage is bounded to 4 uncompressed frames while
decoding, then 3 uncompressed frames (triple buffered)
while looping over the rest.
However, disk usage is N uncompressed frames.

Previously, when resizing a tab, we'd unzoom it, recompute the resize
deltas and adjust every pane's non-zoomed position and re-zoom the
original pane.
When the alt screen is active, wezterm doesn't reflow resized lines,
and there a number of situations where the only effective change to
the line was updating a seqno; the content of those panes doesn't
actually update until the application(s) attached to the PTY
receive SIGWINCH from the kernel.
Since we were resizing the zoomed pane twice in quick succession
we could double-tap SIGWINCH and the application might coalesce
and process only one of the resize events.
The result of that was that we might see the state from either
the first or second resize event and then not get any other updates
until the application repainted itself.
This commit re-structures the resize behavior around zooms so that
we only resize the zoomed pane. When unzooming we'll fixup the
no-zoomed sizes for the whole tab. That means that we need to
store the pre-zoom size in order to correctly calculate those
sizes for the case where a pane was zoomed, the tab resized, and
then the pane was unzoomed again.

Threads through a GuiPosition from mux window creation to allow it to be
used when the corresponding gui window is created.
SpawnCommand now has an optional position field to use for that purpose.
```lua
wezterm.mux.spawn_window {
position = {
x = 10,
y = 300,
-- Optional origin to use for x and y.
-- Possible values:
-- * "ScreenCoordinateSystem" (this is the default)
-- * "MainScreen" (the primary or main screen)
-- * "ActiveScreen" (whichever screen hosts the active/focused window)
-- * {Named="HDMI-1"} - uses a screen by name. See wezterm.gui.screens()
-- origin = "ScreenCoordinateSystem"
},
}
```

The motivation here was to remove some similar but not quite the same
logic that existed for starting up when using `wezterm connect`.
Now `wezterm connect DOMAIN` is implemented as `wezterm start --domain
DOMAIN --attach --always-new-process` and a little extra hand-wave to
ensure that the default domain is set correctly.
The startup events have been refactored a bit; a new gui-attached
event is emitted after attaching and starting any default programs
in the selected domain at startup.
That event can be used to maximize windows and so on, if desired.
The gui-attached event is independent of the startup command and fires
for `wezterm connect`, which `gui-startup` did not (and could not) do.
config_builder helps to make issues more visible/useful in the case
where you may have typod a config option, or otherwise assigned
an incorrect value.
The tcgetpgrp call appears to have high variance in latency, ranging
from 200-700us on my system.
If you have 10 tabs and mouse over the tab bar, that's around 7ms
spent per frame just figuring out the foreground process; that doesn't
include actually extracting the process executable or current working
directory paths.
This was exacerbated by the mouse move events triggering a tab bar
recompute on every pixel of mouse movement.
This commit takes the following steps to resolve this:
* We now only re-compute the tab bar when the UI item is changed by
a mouse movement
* A simple single-item cache is now used on unix that allows the caller
to proceed quickly with stale-but-probably-still-mostly-accurate data
while queuing up an update to a background thread which can absorb
the latency.
The result of this is that hovering over several tabs in quick
succession no longer takes a noticeable length of time to render the
hover, but the consequence is that the contents of a given tab may be
stale by 300-400ms.
I think that trade-off is worth while.
We already have a similar trade-off on Windows, although we don't
yet do the updates in a different thread on Windows. Perhaps in
a follow up commit?

On my mac, depending the config, I noticed that modals didn't always
render immediately; force a window invalidation after assigning to
encourage them to do so.
In https://github.com/wez/wezterm/issues/2932 the user desired to have
brightened text without the boldness, as they were accustomed to that
behavior in a couple of other terminal emulators.
This commit changes the `bold_brightens_ansi_colors` from a simple
boolean to a tristate that allows for not changing the brightness,
changing the brightness, and changing the brightness while adjusting
the boldness down to normal levels.
boolean values are accepted for backwards compatibility.

This took a decent amount of effort to thread through with context;
wrappers around NSMenu and NSMenuItem are added to reduce some of
the objc usability warts, and an additional NSObject wrapper is
added to help copy the KeyAssignment from the existing list
of command palette commands and associate it with the menu item.
When a menu item is selected, macOS will walk through the responder
chain and look for a responder that responds to the selector associated
with the menu item. In practice that means that our window/view class
will be tried first, and then later, our app delegate will be tried.
This commit implements routing from both of these: the window case
routes to the associated TermWindow and drops into the existing
perform_key_assignment method.
In case there is no window (not currently possible, but will be
in the future), the app delegate also has a placeholder for dispatching
key assignments, although it will only be able to perform a subset
of the possible actions.
A couple of things to note:
* Items aren't smart enough to disable themselves or adjust their
caption based on the context. To make that work, we either need
to recreate the entire menubar when any possible context changes
(doable, but feels heavy), or we need to assign a target to each
menu item and implement a validation handler on that target.
That seemed to mess with the responder chain when I briefly
experimented with it.
* There's some disabled code to add a Services menu. It is disabled
because when it is enabled, accessing either Services or Help
from the menu bar sends the process into a busy loop somewhere
in macOS's internals. It's unclear what it is unhappy with.
* No keyboard accelerators are associated with the menubar yet.
That needs some thought, as they would essentially become global
keyboard shortcuts and take precedence over the shortcuts defined
for other keys in the config. This feels like it should be something
that the user has control over, so there needs to be something to
allow that before we go ahead and wire those up.

This sequence forms a grapheme with cell_width=2, but harfbuzz returns
it as two distinct clusters, causing our prior logic to shape them
independently from different fonts, but our logic for assessing width
would resolve them both to the same cell and double-count their width,
leading to issues with the rendered result.
This commit revises our clustering logic to add a pass that compares
the harfbuzz cluster positions with the cell-based positions from
the presentation_width that may have been provided. We use the starting
cell positions from that to order and de-dup so that clusters aren't
split in the wrong place.

dead when the remote indicates that a pane has been removed.
The mapping should be re-established as needed later on.
