The issue is that we work hard to match the keys pre-composition,
but for French and Norwegian layouts ALT-number are valid,
useful punctuation keys. It's awkward to make exceptions for
ALT keys when matching assignments, especially on macOS, and
the simplest thing to do is simply to remove the assignments
and leave it to our users to add their own if they want them.
The ctrl-shift and cmd based assignments are generally much
easier to keep, because those key combinations are not widely
used default mappings on any keyboard layout.

This resolves some issues with non-US layouts (French, Norweigan)
where ALT-number are important and useful punctuation that we were
otherwise blocking.
This new behavior seems consistent with eg: vte terminals on linux
when switching to a French layout.

`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.

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
```

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 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!

If we know that the remote host is a unix system, and that it uses some
version of the posix shell, then we can adjust our command line to cd to
the requested directory (as set by OSC 7) and then exec the requested
command.
That's what SshDomain::assume_unix indicates and what this commit does.
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.
