Expand on the changes in 3f6ff534d3,
this makes them more general and so that they can be used on unix
systems.
That in turn helps to tackle https://github.com/wez/wezterm/issues/839,
wherein `sleep 300 & disown ; exit` would linger until EOF is detected,
rather than triggering as soon as the child process terminated.
For whatever reason, that would only manifest on linux (and not macos).
Since removing the regular periodic background tasks, we're now
prone to not noticing child processes exiting.
This commit explicictly schedules a thread to do that on Windows
so that we can close a tab as soon as it exits.
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

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.

This is one of those massive time sinks that I almost regret...
As part of recent changes to dust-off the allsorts shaper, I noticed
that the harfbuzz shaper wasn't shaping as well as the allsorts one.
This commit:
* Adds emoji-test.txt, a text file you can `cat` to see how well
the emoji are shaped and rendered.
* Fixes (or at least, improves) the column width calculation for
combining sequences such as "deaf man" which was previously calculated
at 3 cells in width when it should have just been 2 cells wide, which
resulted in a weird "prismatic" effect during rendering where the
glyph would be rendered with an extra RHS portion of the glyph across
3 cells.
* Improved/simplified the clustering logic used to compute fallbacks.
Previously we could end up with some wonky/disjoint sequence of
undefined glyphs which wouldn't be successfully resolved from a
fallback font. We now make a better effort to consolidate runs of
undefined glyphs for fallback.
* For sequences such as "woman with veil: dark skin tone" that occupy a
single cell, the shaper may return 3 clusters with 3 glyphs in the
case that the font doesn't fully support this grapheme. At render
time we'd just take the last glyph from that sequence and render it,
resulting in eg: a female symbol in this particular case. It is
generally a bit more useful to show the first glyph in the sequence
(eg: person with veil) rather than the gender or skin tone, so the
renderer now checks for this kind of overlapping sequence and renders
only the first glyph from the sequence.
This causes `tmux -CC attach` to enter control mode and patch
into the terminal, printing out parsed event messages.

This commit moves a bunch of stuff around such that `wezterm` is now a
lighter-weight executable that knows how to spawn the gui, talk to
the mux or emit some escape sequences for imgcat.
The gui portion has been moved into `wezterm-gui`, a separate executable
that doesn't know about the CLI or imgcat functionality.
Importantly, `wezterm.exe` is no longer a window subsystem executable
on windows, which makes interactions such as `wezterm -h` feel more
natural when spawned from `cmd`, and should allow
`type foo.png | wezterm imgcat` to work as expected.
That said, I've only tested this on linux so far, and there's a good
chance that something mac or windows specific is broken by this
change and will need fixing up.

This commit adds very basic first passes at representing the Pane
and GuiWindow types in lua script.
The `open-uri` event from 9397f2a2db
has been redefined to receive `(window, pane, uri)` parameters
instead of its prior very basic `uri` parameter.
A new key assignment `wezterm.action{EmitEvent="event-name"}` is
now available that allows a key binding assignment to emit an arbitrary
event, which in turn allows for triggering an arbitrary lua callback
in response to a key or mouse click.
`EmitEvent` passes the `(window, pane)` from the triggering window and
pane as parameters.
Here's a brief example:
```lua
local wezterm = require 'wezterm';
wezterm.on("my-thingy", function(window, pane)
local dims = pane:get_dimensions();
wezterm.log_error("did my thingy with window " .. window:window_id() ..
" pane " .. pane:pane_id() .. " " .. dims.cols .. "x" .. dims.viewport_rows);
window:perform_action("IncreaseFontSize", pane);
end)
return {
keys = {
{key="E", mods="CTRL", action=wezterm.action{EmitEvent="my-thingy"}},
}
}
```
