Use some heuristics to verify the data that is about to be parsed;
this can help to detect eg: data being output to stdout prior
to us sending any encoded data to the remote mux.
In addition, add a timeout to help avoid waiting forever in
the case that we didn't detect a problem.

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).

There were a a couple of issues:
* `ImageData::hash` would re-hash the image on every call, and this was
called for every cell that comprised an image on the mux server side
* `SerializedLine` needed to understand how to remove the `Arc<ImageData>`
image attachments so that we didn't serialize a complete copy of the
image per cell that comprised the image.
A new RPC was introduced to attempt to fetch `ImageData` given its
content hash and pane, row and cell index as a hint to locate it.
A client side LRU of content hash to `ImageData` is used to avoid
issuing repeat calls to that new RPC.

wezterm cli spawn, and wezterm cli split-pane can use this information
to pick a default for the pane id when invoked from outside of wezterm.

This commit does two related things, from opposite ends of the spectrum:
* Sets the sticky bit on pid files and unix sockets to avoid tmpwatch
deleting them in cleanup scenarios
* Falls back to looking at the changed time if the filesystem doesn't
support reporting creation time when wezterm does its own liveness
and cleanup checks for unix domain sockets in the runtime dir
* Allow any wezterm instance to perform that cleanup

This reverts commit a189bb57c14ec2245f276a077fbe13a88622c1d7;
it turns out that we do need to send those bonus lines because
the sequence number available to the logic here doesn't account
for the actual last rendered sequence number on the client, and
in a bursty update situation we can skip or otherwise omit a
line range.

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
The mux now has a notion of which client is actively doing things.
This allows, for example, newly spawned windows to take on the
active workspace for a given client.
The gui now assigns a client id on startup, and sets the active
workspace to `default`.
The mux server temporarily overrides the active id to that of
the currently dispatching client when processing PDUs.

Tidies up some code duplication within the mux protocol handler.
Move some of the logic into Mux, remove legacy Spawn Pdu to reduce
more duplication.
I want to dedup some of the similar logic that exists in the gui
spawn implementation as well in a follow up.
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.

Define a way to compute a client ID and pass that through to the
mux server when verifying version compatibility.
Once associated, the session handler will keep some metadata
updated in the mux.
A new cli subcommand exposes the info:
```
; ./target/debug/wezterm cli list-clients
USER HOST PID CONNECTED IDLE WORKSPACE
wez mba.localdomain 52979 30.009225s 1.009225s
```

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 is slightly misusing or misattributing things, but in
the context of the problem at hand, it is OK.
The issue is that palette changes are normally signalled by
the terminal instance in response to escape sequences. Those
changes are propagated to the mux client through the existing
alerting channel.
If the palette is changed implicitly via a config change, then
the terminal doesn't trigger that alert and the mux client(s)
don't know that they need to refresh the palette.
This commit tracks the last config generation per pane and
synthesizes a palette alert when it changes.
It might be better to have another variant of alert to indicate
config changes.

This doesn't make a huge difference; I think we already addressed
the worst of the overhead with a combination of
eae327efcc
and the more recent commits to avoid over invalidation around
cursor movement and screen scrolling.
The numbers I see are a very small number of bytes per second when
scrolling through eg: vim and aren't crazy or alarming.
So I'm going to consider the related issue resolved!

Rather than using the configured initial window size, use the
size of the current tab to size the newly spawned tab.

Terminal now maintains a sequence number that increments
for each Action that is applied to it.
Changes to lines are tagged with the current sequence number.
This makes it a bit easier to reason about when an individual
line has changed relative to some point in "time"; the consumer
of the terminal can sample the current sequence number and then
can later determine which lines have changed since that point
in time.

This commit causes a window-config-reloaded event to trigger
when the appearance (dark/light mode) is changed on macos.
It also arranges to propagate the window level config to newly
spawned panes and tabs, created both via the gui and via the
CLI/mux interface.

Same vein as 8931afba5cee07ab12990f06c2ff34d6f8426b19; the auth
window could sometimes get stuck until an input event was sent
to it.
Wire up a mux event so that the window can close itself.
in the same vein as d657721163
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.

When running the GUI, we generate a unix domain socket path for
the current process and start up a mux server for that path.
This allows `wezterm cli list` and `wezterm cli split-pane` to
work implicitly inside the GUI session.
When started in this way, the mux server is not persistent;
when the GUI process is terminated, all of its windows, tabs
and panes are terminated.
