e6421d1b72 pty: try_clone_writer -> take_writer
This breaking API change allows us to explicitly generate EOF when the
taken writer is dropped.

The examples have been updated to show how to manage read, write
and waiting without deadlock for both linux and windows.
Need to confirm that this is still good on macOS, but my
confidence is high.

I've also removed ssh2 support from this crate as part of this
change. We haven't used it directly in wezterm in a long while
and removing it from here means that there is slightly less code
to keep compiling over and over.

9cd72fefe2 pty: cmdbuilder: check for executable access when resolving program
`wezterm start -- /etc/profile` would crash on macOS because
`/etc/profile` isn't executable.

This commit checks for executable access as a prereq for both the
path search and the absolute path cases and generates a non-crashing
error:

```
$ wezterm start -- /etc/profile
17:24:03.574  ERROR  wezterm_gui > Unable to spawn /etc/profile because it doesn't exist on the filesystem or is not executable (EACCES: Permission denied); terminating

d64bc7248e pty: pre-fill base env from registry env settings on Windows
I think I'd like to make a config option for this, but for the moment,
this first pass unconditionally updates the base environment with
data from the registry.

a0cbea2703 term: ignore first OSC title change sequence on Windows
ConPTY emits a sequence that sets the title to the name of the
program that is initially launched into it.

This commit tries to ignore that sequence in that circumstance,
so that the logic in b5d156c282
can more dynamically set the tab title.

7926c31209 pty: introduce ChildKiller trait
In the mux layer, we have some code that takes a `Child` and then
does a bit of naughty reaching through the abstraction to get at
the pid/handle of the child so that we can send it signals even
if the child is itself mutably (and thus exclusively) borrowed
for the purposes of waiting.

That worked fine for local processes spawned in the mux, but we also
use LocalPane to wrap around arbitrary `Child`ren, such as Ssh,
that are not local and that don't have a local process id, which
meant that this hack wouldn't work for them.

To make things a bit worse, those ssh ptys were used to ssh2 days
where we didn't have a way to signal the remote process and just
did nothing, leading to confusing situations such as
https://github.com/wez/wezterm/issues/1197

This commit graduates the hack mentioned in the first paragraph
to its own ChildKiller trait.  This makes the concept of waiting
for the Child distinct from signalling it and explicitly allows
getting a separate object that can be used for signalling.

With that in place, we're forced to implement something appropriate
for the ssh pty implementations; one in the pty crate itself,
one in wezterm-ssh and the wrapper that we use in the mux crate.

The upshot of this is that the `CloseCurrentPane` action now operates
correctly on panes that were the result of split operations.

3f6ff534d3 windows: fix lingering cmd.exe panes
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.

e818ad9dd1 pty, wezterm: add support for serial ports
Tested only on windows with a USB serial connector to my NUC running
linux.

This allows opening up wezterm on a serial port connection.
Serial is closer to a tty than a pty, so it is a bit different
to configure and use.

This commit allows running:

```
wezterm serial COM3
```

to open a window that connects to the specified COM port.

You can change the baud rate with:

```
wezterm serial --baud 9600 COM3
```

There are more options that could be set, but I'm a bit lazy and
have only exposed the baud rate to the wezterm cli so far.
