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.

Originally I had this the other way around but it was problematic
when considering things like maximized, font scaling and full screen
states.

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.
refs: #1531
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.

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.
`ScrollByPage` can accept non-integer values in the configuration.
This allows fractional page scrolling, such as by half a page.
The default remains the same, at 1 page.
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.

This is a similar race condition to one we had before with the
multiplexer, where the connection UI made us think that we didn't
need to start a new process.
Additionally, the attach method would unconditionally create a
new client without checking whether we already had one.
In the case that the published symlink is stale, our default
client connection logic was to retry connecting with backoff
to give a newly spawned server a chance to startup.
In the context of a newly launched gui process checking to see
if an existing gui process can serve the same request, we don't
need to give it any grace: it will either answer immediately
or be deemed not useful.
This commit limits us to a single connection attempt in the case
where we're not automatically starting the server, which in turn
constrains the overhead to something in the order of microseconds
rather than nearly 0.5 seconds.
While we're in here, I noticed that if we thought we had a socket
to try and that failed, we'd always try to publish a new symlink.
However, if we failed due to mismatched version info, we shouldn't
publish over the top of the already running instance.

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 puts us in a better position for the future to be able
to configure whether we use wezterm, tmux or no multiplexing.
Today we allow wezterm or no multiplexing.
Add docs on this new setting.

If an ssh domain is set to use_multiplexer=false, it is now
possible to `wezterm connect` to it.
Previously, it was only possible to connect to domains that
used the mux client.

If we decide we want re-use and existing gui due to config differences
we shouldn't then publish the new, differently configured, gui as
the canonical path for that display/class.
Clarify the message that we print when re-using an existing gui
in case someone doesn't want that behavior.
When set, changes the default domain to the domain with the specified
name, which potentially affects the default program.
eg: default_domain = "WSL:Ubuntu-18.04" will cause the initial tab
to be spawned via WSL.
The idea is that we want to be able to spawn into wsl with the
convenience of a local domain, but without the awkwardness of
it having a different filesystem namespace.
It would also be great to be able to spawn a new tab or pane
in the same domain and pick up the cwd of the existing one.
The WslDomain allows the user to explicitly list WslDomains
and control eg: default shell, username and so on, but wezterm
will pre-fill a default list of domains based on the `wsl -l`
output that we were already using in the launcher menu.
The existing LocalDomain has been augmented to understand that
it may need to fixup a command invocation and that gives it
the opportunity to rewrite the command so that we can launch
it via `wsl.exe` and pass down the cwd and so on.
This same technique might be extensible to eg: docker instances
in the future.
This commit:
* Introduces `wsl_domains` config and its default list of wsl
distributions
* Creates LocalDomain instances from that list
* The launcher menu allows spawning a new tab via one of those domains
The client machinery would try to spawn an async attempt at
detaching the unixdomain from the mux on shutdown, but since
we're in the middle of tearing down the scoped executor,
we could sometimes panic.
The client we have in this situation isn't actually associated
with a domain, so we don't need to detach in that situation.
Formalize that by making it an Option, and address the
fanout.
Using the new publish/discovery stuff from the past couple of commits,
if we can find a matching socket path for a running gui, and the
configuration is likely a match, then use the mux protocol to talk
to the already running gui and ask it to spawn the equivalent program
into the same process.

We need 100% of the info for it to work correctly, so this commit:
* Exposes the keyboard encoding mode via the Pane trait
* Adds the scan code to the RawKeyEvent
* Has the GUI perform the encoding if the keyboard is set that way
* Removes the basic encoder from termwiz in favor of the gui level one
The net result is that we bypass the Pane::key_up/Pane::key_down methods
in almost all cases when the encoding mode is set to win32-input-mode.
There is now a config option: allow_win32_input_mode that can be
used to prevent using this mode.

When spawned with no WEZTERM_UNIX_SOCKET environment set,
we now prefer to resolve the gui instance, falling back to
the mux if it doesn't look like the gui is running.
`wezterm cli --prefer-mux` will use the original behavior of
trying to resolve the path from the unix domain in the config.
