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.

It's a tremendous PITA for the user to do this at the system level on a
mac, where it is sorely needed. This commit allows raising to a desired
minimum level, but won't decrease from an already larger soft limit.

Add a link to regex syntax supported in wezterm, so eg. we have a way to know that perl character class '\c' is not supported and instead we can use the ascii equivalent [:cntrl:]
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
command palette, but is also the root cause of another issue
with CharSelect mode.

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
when the active pane is changed.
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.
refs: #2863
* Translate from File to EncodedFile as needed
* Adopt blob leases in the mux server
* Fix an issue where the first image sent by the mux server would
be replaced on the client by its background image, if configured.
Removed the ImageData::id field to resolve this: you should use
the hash field instead to identify and disambiguate images.
Bumped the termwiz API version because this is conceptually
a breaking change to the API

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).

and allows this:
