* Make alphabet and patterns configurable
* add docs
* Enhance scrollback search to support regex captures so that
searching for eg: `fo(o)` will select the last `o` in `foo`.

This tidies up how we pass the ssh config to the connection ui
logic, by moving the ssh_config setup to the two callers.
A couple of notable adjustments:
* SshDomain::username is now optional; it will default to the
values computed by the ssh config file loader
* no_agent_auth value wasn't hooked up to anything, but now it is

We weren't fixing up the active tab position correctly after removing
a tab. I think this bug crept in around the ActivateLastTab changes.
We now try harder to set active idx back to the tab that was active
prior to the remove, and ensure that we set the active index to
something within range if it was the active tab that was removed.

We were handling the case where the chunk intersected a multibyte
boundary after the first chunk, but not for the first chunk itself.
Refactor the code so that we use the same chunk splitting logic
for both of those cases.

This function could return 1 more line than was requested in the case
where resizing had caused long lines to rewrap.
That extra line would cause the partial bottom row of the quads to
populated with bogus data and rendered over the top of the background
fill.
The resolution is to stop populating lines once we've reached the
upper bound based on the input range.

This replicates `last-window` in tmux. To pull this off, I
deliberately store the last tab whenever I'm activating a new one or
spawning a new one. I had to do this explicitly rather than hooking
set_active, because we end up setting the active tab briefly for some
common operations like moving a tab.
There are a few notable changes as a result:
* A number of `.ssh/config` options are now respected; host matching
and aliasing and identity file are the main things
* The authentication prompt is inline in the window, rather than
popping up a separate authentication window

These now operate in terms of logical lines so they deal with
lines that have wrapped outside the viewport better than in
previous releases.

The wincng based build doesn't recognize newer keys which makes it
impossible to connect to a reasonably up to date Fedora installation.
This commit points to my branch of ssh2-rs that has some changes to
build ssh2 against the vendored openssl that is already part of
the dependency graph for wezterm.

I don't understand how fish ends up blocking forever in the related
issue, but it shouldn't block us too! The price of this situation
is likely a lingering zombie child process but that seems fine.

I've had a few people comment that the screen repaints stutter
more since the most recent release.
One of the main changes in that area was to increase throughput
for timg case, where a lot of data was being pumped through.
I think that, ironically, the decreased latency results in more
frequent repaints where not all of the updated screen is visible
in a full screen redraw, so it appears more janky.
This commit introduces a small 1ms delay to see if additional
output is forthcoming when parsing the data. It will keep
delaying and accumulating until there's at least one parsed
output action to process, so there is a small constant latency
overhead added to a single character output (thread context
switch + 1ms delay).
This small delay is counter-balanced with raising the priority
of dispatching the render actions; previously we'd spawn them
at lower-than-input priority. With the batching potential,
I think spawning them at the same priority is OK; the main
reason for the lower priority was to ensure timely ctrl-c
processing when a lot of output is being dumped to the terminal.
It's hard for me to gauge whether this fixes the reported issue,
as I've been unable to reproduce it for myself.

I'm not convinced that this is 100% good, but @fanzeyi reported
some latency when using tmux to mirror two sessions. The session
that was accepting interactive input responded quickly, but the
mirroring session was laggy.
This change connects the mux pane output event to window invalidation,
which should cause repaints to happen more often.
I couldn't reproduce the scenario above on my M1 mac, but that may
just be because M1 has dark magicks.
I've been meaning to do this for a while; this commit moves
the escape sequence parsing into the thread that reads the
pty output which achieves two goals:
* Large escape sequences (eg: image protocols) that span multiple
4k buffers can be processed without ping-ponging between the
reader thread and the main gui thread
* That parsing can happen in the reader thread, keeping the gui
thread more responsive.
These changes free up the CPU during intensive operations such
as timg video playback.
This is a slight layering violation, in that this processing
really belongs to local pane (or any pane that embeds Terminal),
rather than generically at the Mux layer, but it's not any
worse a violation than `advance_bytes` already was.

In a couple of quick tests, this doesn't seem to break cat'ing
the emoji test data so it seems like it isn't needed anymore.
In addition, it removes a bottleneck from processing image
streams produced by timg, which tend to be very large with
new newlines.
With this change, I'm able to view a 25fps source video at
about 60fps.

This is defined as a trait method on Pane (default: false), and has the
obvious transitive equivalent methods in Tab and Window (eg: if all
contained items are `can_close_without_prompting`, then that container
is also `can_close_without_prompting`).
The intent is to avoid bothering the user to confirm closing a window
when the content is not stateful and doesn't warrant it.
For example: the window that is displayed in the event of a
configuration error really shouldn't prompt to the user to confirm
closing it.
All termwiztermtab panes are `can_close_without_prompting==true`
to effect this policy.
In the future, we could teach LocalPane to lookup the session leader
process against a list of "uninteresting" or "stateless" processes
and return an appropriate result (as suggested in
https://github.com/wez/wezterm/issues/280). That functionality
is NOT part of this commit.
`exit_behavior = "Hold"` will keep the pane alive until explicitly
closed. More details in the docs that are part of this commit.

* Add ClearBuffer action
Clears all lines, both visible and those scrolled off the top of the viewport, making the prompt line the new first line and resetting the scrollbar thumb to the full height of the window.
This is the behavior that Hyper / xterm has for clearing the terminal.
* Combine ClearBuffer into ClearScrollback as enum with associated erase mode
Makes it easier to manage the different options of clearing the terminal.
This appears to have been broken since the introduction of mouse
assignments :-/
This commit adds Pane::is_alt_screen_active so that the gui layer
can tell whether the alt screen is active, and allow passing down
the event.

It's been replaced with an opaque termwiz error type instead.
This is a bit of a more conservative approach than that in (refs: #407)
and has less of an impact on the surrounding code, which appeals to
me from a maintenance perspective.

Following on from 8649056ac0,
this commit should make it harder to make a similar mistake
in the future, by introducing a new TerminalSize struct for
that purpose.
* Allow injecting some initial output to new panes
* Have the update checker set this new-pane-banner to a short
upsell to let the user know there is an update.
* Refactor toast notifications into their own crate
* Have the update checker call a new stub function that triggers
a toast notification with an URL... but it does nothing because
the rust ecosystem doesn't support this on macos yet and I'm
writing this code there
Tidies up the plumbing around pixel dimensions so that ImageData
can be rendered via the termwiztermtab bits.
I put this together to play with sticking the wezterm logo in
the close confirmation dialogs. I didn't end up using that though,
but have preserved the commented code for use in future hacking.
Revise logging so that we use info level for things that we want
to always log, and adjust the logger config to always log info
level messages.
That means shifting some warning level logs down lower to debug level so
that they aren't noisy.
