This allows removing a bunch of unwrap/expect calls.
However, my primary motive was to replace the cases where we used
Mux::get() == None to indicate that we were not on the main thread.
A separate API has been added to test for that explicitly rather than
implicitly.
We weren't matching the domain id when resolving the remote->local pane
mapping, which meant that having 2 or more mux client domains active
would lead to associating eg: remote pane id 1 with whichever local
pane was associated with any remote pane id 1 *first*.
This commit requires that both the domain id and the remote pane id
match.

When closing the all mux tabs in a window, the remote will close
the window. If the local has a mixture of local and remote tabs
then subsequent attempts to spawn a tab in that window would
fail due to reusing the stale remote window id.
This commit purges the local/remote mappings that are (probably)
dead when the remote indicates that a pane has been removed.
The mapping should be re-established as needed later on.

I'd like to push that into the status bar, so nudge people towards
that in the docs for this.
There is a config option to restore it. I'd like to ultimately
remove that though.

* Expose `activate-pane-direction` cli command
Add a new subcommand for `wezterm cli` called `activate-pane-direction`.
It allows switching the active pane in the current tab in the given
direction.
* Bump codec version
* Replace boolean flags with a single direction arg
* Run cargo fmt
The idea here is that different kinds of panes may want to expose
additional metadata to lua scripts. It would be a bit weird to add
a Pane method for each of those and plumb it all the way through
the various APIs, so just allowing a pane impl to return a dynamic
value (likely an Object) allows a bunch of flexibility.
This commit exposes the clientpane is_tardy boolean and the time
since the last data was recevied (since_last_response_ms) from
the mux client pane implementation: these are used to show the
tardiness indicator in the client pane.
Exposing this data enables the user to add that info to their
status bar if they wish.
Tidy some things up to avoid some dead code and redundant impls.
Make it easier to select whether you want to implement the new
methods in terms of the old, or the old methods in terms of
the new in a given pane impl.
Adds Pane::for_each_logical_line_in_stable_range_mut and
Pane::with_lines_mut which allow iterating mutably over lines.
The idea is that this will allow the renderer to directly cache
data in the Line via its appdata without having to build cumbersome
external caching logic and managing cache keys.
This commit just swaps the implementation around for localpane
and sanity checks that the renderer functions.
Various overlays and the mux client don't properly implement these
yet and current warn at compile time and panic at runtime.
To follow is the logic to cache the data and make sure that it
works the way that I think before converting the other Pane
implementations.
It didn't really belong there; it was added as a bit of a hack
to propagate screen reverse video mode.
Move that to the RenderableDims struct and remove the related
bits from Line
This makes those fields usable in `wezterm cli list --format json`.
This doesn't change the ABI of the mux protocol, but prior to
this commit, those fields were always 0.

The recent work on the scrollback made it easier to constrain the
search region, so expose those parameters to the Pane::search
interface and to the mux protocol.
Use those new parameters to constrain quickselect search to
1000 rows above and below the current viewport by default, and
add a new parameter to QuickSelectArgs that allows overriding that
range.
A follow-up commit could make the search/copy overlay issue a series
of searches in chunks so that it avoids blocking the UI when
searching very large scrollback.

The previous commit added the option to convert the storage to
the cluster format. That saves memory as rows are moved to scrollback,
but makes scrolling back more expensive due to that conversion.
This commit adds a fast(ish) path for the common case of simply
appending text to a new line before it gets scrolled: the default
format for lines in the screen is now the cluster format and,
provided that the cursor moves from left to right as text is
emitted, can simply append to the cluster storage in-place
and avoids a conversion when the line is moved to scrollback.
This improves the throughput of `time cat enwiki8.wiki` so
that the runtime is typically around 11-12s (compared to 9-10s
before introducing cluster storage). However, this is often
a deal of variance in the measured time and I believe that
that is due to the renderer triggering conversions back to
the vec storage and introducing slowdowns from the render side.
That's what I'll investigate next.
The fixup callback can now by async, which makes it possible to use
other async functions in the callback.
There is an additional parameter to wezterm.exec_domain that allows
setting the label that is shown in the launcher menu.
It accepts either a string value or an async callback function
that can be used to compute the label dynamically.
This commit allows for the SplitPane internal action to use the
pane id of an existing pane as the source of the pane to be added
in the new split target, rather than spawning a new command.
This can be used to move a pane from one tab to another, and is
analagous to tmux's `join-pane` command.

This, along with the plumbing included here, allows specifying
the destination of the split (now you can specify top/left, whereas
previously it was limited to right/bottom), as well as the size
of the split, and also whether the split targets the node at the
top level of the tab rather than the active pane--that is referred
to as full-width in tmux terminology.

The logic that figures out whether/how to map remote windows
to the potential local window needs to account for the workspaces
on any given local/remote pair.
In particular, if we are called with a primary window id that
has say "default" as its workspace, we mustn't decide to place
remote tabs from a window whose workspace is not "default"
into that local window, or else we can end up in a weird
state where we have 3 workspaces on the remote, but have
accidentally folded one of them into the `default` workspace
and thus end up thinking that we have one workspace with two
windows and one other workspace, instead of the intended
3 windows each with a distinct workspace.

We need to notice when all of the streams associated with a channel are
closed and remove the channel from the set that we're polling in the
main loop, to avoid continually polling the closed descriptors.
Additionally, if the Session has been dropped, we know that we cannot
be asked to create any new channels, so if there are no more channels
then we can and should exit that dispatch loop and allow the resources
to be cleaned up.

The launcher menu code to perform attaching has been generalized

This commit allows the currently active window to:
* Spawn a new tab in the active window (rather than spawning
a new window) to host the connection status
* Auto-close that connection UI tab (rather than the whole window)
when the window is no longer needed
* Pass the current window through to use as the primary window when
assigning remote window/tabs.
The net effect of this is that there are fewer transient windows,
and that it is easier to connect a set of domains to the active
workspace.

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.

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.

After killing the remote pane, we no longer trigger the renderable
poll stuff that would detect that the pane was dead.
Let's speculatively set it to dead so that we don't get stuck with
stray tabs/panes.

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.

Pretty much the same test plan as b4c4c85683
but start wezterm:
./target/debug/wezterm -n --config 'ssh_domains={{name="s",remote_address="localhost"}}' connect s
This reliably propagates focus=true events, but if the client switches
focus away from a mux pane to a local pane, then the focus=false event
may not be propagated to the remote mux.

This was used by the mux client when the session is tardy.
I've heard feedback that the greying out is distracting and not
especially useful, so I don't think this is any great loss.
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

Introduce a new config knob called 'local_echo_threshold_ms' to let
users configure when the local echo prediction should kick in. The
default value is 100ms to retain the current behavior.
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.

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.
