This commit introduces a small, bounded, LRU cache for recently
decoded images.
This allows the same image ID to be used in the cache that the
same image bits are repeatedly sent to the terminal.
This is advantageous because it reduces the amount of texture
space required by the gui layer.
This wasn't used by anything and the version was getting pretty stale.
Upgrading is awkward because newer versions pull in an incompatible
freetype library version.
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 uses the guillotine algorithm to assign rectangles,
which is superior to the dumb algorithm previously in use.
In addition, in the first pass of painting, if we get a texture
space error, we clear the atlas and try again without increasing
it size, which should serve as the ultimate defrag.
Subsequent passes will cause the texture to grow if needed.

Replaces SmallVec with an internal TeenyString that only
occupies a single machine word and avoids heap allocation
in the common case on most architectures. This takes the
textual portion of Cell from 32 bytes to 8 bytes.
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"}},
}
}
```

This was broken by the changes in
aad493ab2a. The issue was that the
channel send didn't wakeup the receiver. I'm not sure why, and I tried
a couple of different async channel implementation.
Doing the simplistic solution here works reliably.
This builds on the new lua event handler plumbing added
in ccea650a93 to co-opt
the default URI opening action:
```lua
wezterm.on("open-uri", function(uri)
if uri:find("jira") then
wezterm.log_error("do something with jira")
wezterm.run_child_process({
"wezterm",
"start",
"--",
"jira",
"view",
extract_task_from_uri(uri)
})
-- prevent the default action from opening in a browser
return false
else
-- log but allow the uri to be opened in the browser
wezterm.log_error("clicken " .. uri)
end
end)
```
This doesn't allow exactly the sketched out option from
issue #223 to be implemented, but may be close enough
to be useful.

* `wezterm.on("event-name", func)`
* `wezterm.emit("event-name", "arg1", "arg2")`
`on` allows registering multiple functions.
`emit` will call each of the registered functions in turn, passing
a copy of the arguments. If a handler returns false, no additional
handlers are called and `emit` will return false. Otherwise,
once all the handlers have been called, `emit` will return true.
`emit` is capable of being called by async code.
These functions are available to the config layer, but nothing in
wezterm uses them at this time.

* Taught wezterm-mux-server how to `--daemonize` on windows
* Removed pty based command spawn used to spawn unix domain servers.
This was present because it was the only way to successfully spawn
wsl in the past. What I'm finding today is that it doesn't work
at all for me, generating an `0xc0000142` Application failed to
initialize error. A plain command builder spawn seems to work,
so that's what we're going with.
* Ensure that we put `.exe` on executable name on windows, otherwise
the spawn may fail.
* `Path::exists()` always returns false for unix domain sockets on
Windows, so unconditionally try to remove the socket before binding,
otherwise the bind will falsely fail, claiming that another process
is already bound.
The docs for mux will need to be updated to show how to revise them
for the new mux server invocation:
```lua
unix_domains = {
{
name = "wsl",
serve_command = {"wsl", "wezterm-mux-server", "--daemonize"}
},
}
```
This version no longer generates invalid CA certificates and
allows TLS connections using the internal PKI to advance
further. Still need to debug an early disconnect.
kindof a lot going on in this commit, unintentionally:
* Need the lua context set to be moved into the config crate
otherwise configs cannot be parsed by the server and we end
up with the default configs
* Make the server use smol for async io
* Drop the use of the daemonize crate, which I had forked anyway.
Just inline our own tighter daemonize module
* Improve daemon spawning synchronization, however, it still needs
work for windows to avoid blocking forever where we don't do
daemonizing.
This commit adds support for left/right margins and has been
tested against esctest, with a final status of:
```
309 tests passed, 239 known bugs
```
"known bugs" also includes unimplemented features; we have a
similar degree as iTerm2.
As of this commit, we now report as a vt520ish machine to DA1.
I confess to not having read enough of the relevant docs
to know whether this is totally righteous.
