Implement an app delegate to receive a callback when the system
requests that we open `.command` files, and then ask the mux
layer to spawn a window for it and execute it via the shell.
Also allow handling `.sh`, `.zsh`, `.bash`, `.fish` and `.tool`,
per kitty.

Since the initial attach is async, we'd create the window at the
default/initial size and then never reconcile the size of the remote
tabs once they'd attached.
This commit introduces an event that allows the gui window to do that.
The action that it takes is to take the max width and height between
its current size and the size of a newly added tab and resizes to
that new size, if it changed.

This simplifies the "change scheme based on dark mode" example
a lot. This was previously impossible to do because we didn't
have a lua module associated with the gui until recently, so
the only way to reference a gui-related object was via an
event callback.

Attach the mux events to the frontend workspace reconciliation function
so that the window is updated to match the new workspace.
Ensure that we correctly clear out any overlay panes as part of the
switch: we need to remove them from the mux so that the mux will
correctly identify that the mux is empty when the main panes from
the workspace are closed. The problem case was that the debug overlay
state was forgotten by the gui when activating the new workspace, but
we didn't tell the mux to kill it off, so subsequently CTRL-D'ing
the windows closed the windows but left the wezterm process running with
no head.

reconciling causes gui windows to be created and allows for stuff like
this, that would otherwise fail because the gui window hadn't been
created yet.
```lua
local wezterm = require 'wezterm'
local mux = wezterm.mux
wezterm.on("gui-startup", function()
local tab, pane, window = mux.spawn_window{}
window:gui_window():set_inner_size(1200, 1200)
end)
return {
}
```
This is a bit of an unsatisfactory commit... the bulk of it is
augmenting our calls into XCB to ensure that we check the status of each
request; the idea was that doing so would highlight the source of the
bad drawable error that is being surfaced in #2198, but after doing
that, it still doesn't highlight the offending call.
My conclusion is that either something in MESA/EGL or the IME is
generating calls that we cannot see into and that one of those is
referencing the window id that we just destroyed.
The resolution then is a bit gross: instead of destroying the window
when we need to close it, we first unmap it to remove it from the
screen, then after 2 seconds we destroy it.

Previously, the mux layer had no internal understanding of titles other
than the Pane::get_title method to return state from a pane.
Users have asked for ways to explicitly set titles on windows and tabs,
so this commit is a step towards that.
The mux window and tab objects now store a title string.
The terminal layer now emits Alert::WindowTitleChanged when the window
title is changed via eg: OSC 0 or OSC 2.
The mux layer will respond to Alert::WindowTitleChanged by resolving the
window that corresponds to the source pane and amending its title.
The MuxWindow and MuxTab objects now provide accessor methods for the
title.
TabInformation (as used by format-tab-title and format-window-title) now
exposes the underlying window_id as well as tab_title and window_title.
The tab title can be changed via the lua MuxTab type, but there is not
currently an escape sequence associated with this.
The defaults for format-tab-title and format-window-title don't
currently consider these new title strings.

The heart of the issue here was due to the window-reuse logic that
tries to reuse a GUI window that is no longer associated with a mux
window.
Each GUI window subscribes to the mux for mux events, but it filters
according to is understanding of the mux_window_id that it is associated
with.
The GUI frontend maintains an mapping of GUI and mux window so that it
knows when to reuse a GUI window and when to close it.
When connecting to a remote mux, wezterm spawns a temporary connection
progress window. Once connected, workspace reconiliation is triggered
and decides that this window can be used for something else.
As part of workspace reconciliation, this mapping can be adjusted and
the frontend will notify a GUI window that its mux window has changed.
However, that updated mux window was not visible to the mux notification
subscription so the effect was that a variety of notifications were
effectively ignored, including updates from a remote mux when the output
was changed.
To make matters worse, the workspace reconciliation could "double-tap"
window creation and create excess windows only to later realize they
weren't needed and close them out again.
This commit addresses both of these concerns.

The glium IncompatibleOpenGl Display doesn't include any of the
useful context to explain what the issue was, so this commit

Previously, we'd create a clipboard handler associated with a GUI window
and take care to pass that down to the underlying Pane whenever we
spawned a new pane.
For the mux server, instead of being associated with a GUI window, the
clipboard was a special RemoteClipboard that would send a PDU through
to the client that spawned the window.
The bug here was that when that client went away, the clipboard for
that window was broken.
If the mux server was the built-in mux in a gui process this could
leave a tab without working OSC 52 clipboard support.
This commit restructures things so that the Mux is responsible for
assigning a clipboard handler that rephrases the clipboard event
as a MuxNotification.
Both the GUI frontend and the mux server dispatcher already listen
for mux notifications and translate those events into appropriate
operations on the system clipboard or Pdus to send to the client(s).

This commit enables the following config to work for local (not mux yet!)
panes:
```lua
local wezterm = require 'wezterm'
wezterm.on("format-tab-title", function(tab, tabs, panes, config, hover, max_width)
if tab.is_active then
return {
{Background={Color="blue"}},
{Text=" " .. tab.active_pane.title .. " "},
}
end
local has_unseen_output = false
for _, pane in ipairs(tab.panes) do
if pane.has_unseen_output then
has_unseen_output = true
break;
end
end
if has_unseen_output then
return {
{Background={Color="Orange"}},
{Text=" " .. tab.active_pane.title .. " "},
}
end
return tab.active_pane.title
end)
return {
}
```

This isn't ideal, but it is better than previously: we would
close the window and before the Drop impl had updated the
list of known windows, we'd try to re-assign that window
to another mux window in a different workspace, but it would
never appear because the window was closed.

Rather than just quitting the app and potentially silently killing off
a number of panes that might be running in other workspaces, we now
will pick one of those workspaces and activate it.

This action causes the active workspace for the gui to change.
If the name is omitted a random name will be generated.
If the workspace doesn't exist, it will be be created.
The optional spawn parameter can be used to launch a specific
program into the new workspace; if omitted, the default prog
will be used.
The gui only supports a single active workspace. Switching workspaces
will repurpose existing gui windows and re-assign them to windows
in the new workspace, adjusting their size to fit those windows,
spawning new windows or closing unused windows as required.
The gui now exits when there are no panes in the active workspace,
rather than no panes at all.
refs: #1531
This is not exposed through any UX; the mux api allows setting
the workspace and propagating information about windows whose
workspace has changed.
Windows start with a blank workspace name.
This is just plumbing; nothing uses it yet.

user vars were stubbed out. This commit adds storage for them
in the mux client and adds a new notification that publishes each
var as it is changed. That differential stream is applied to the
storage in the mux client when it is received.
```lua
local wezterm = require 'wezterm'
wezterm.on("update-right-status", function(window, pane)
local woot = pane:get_user_vars().woot
window:set_right_status(tostring(woot))
end);
return {
unix_domains = {
{name="unix"},
},
}
```
then running:
* `wezterm connect unix`
* in that session: `printf "\033]1337;SetUserVar=%s=%s\007" woot `echo -n nice | base64``
causes `nice` to show in the status area.

This commit adjusts the the window event routing/queuing so that
a queued event can capture a pane_id other than the focused pane.
Since we only allow one queued instance of a given named event in a
window, a consequence of this is that multiple bell events coming
from different panes at the same time may race and the loser's
event will be dropped. We log a warning in that case.

this commit introduces more assertive signalling from the remote
mux when a pane is closed so that the client can update.
As part of reducing the amount of regularly scheduled stuff wezterm
does in the background, this commit restructures how an empty mux
is detected; now when the mux prunes dead windows it will emit
an Empty event.
The Activity type will now schedule a prune when it is dropped,
which will clean up and trigger the Empty event.
