Looking at #900; the unconditional directory change on startup
is "bad" because it only happens on Windows.
This commit removes it and instead puts the logic into the pty
layer to match the unix behavior.
The behavior is:
* If the command specifies the cwd, use that.
* Otherwise, use the home directory
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.
Since the original code was written, Rust grew and stabilized
an interface for specifying argv0 for the child process, so
we can remove the fragile `-l` argument passing.

This commit first delivers SIGHUP, then follows up with a regular
kill after a grace period. This should allow processes an opportunity
to clean up when eg: the terminal window is closed.

* Add Sync marker to child process created through pty spawn
* Add 'Sync' to Windows build of pty
* Wrap proc in WinChild in a Mutex
* Make sure the Mutex is not locked for long by cloning
* Add config option to specify default current working directory
* Make `cwd` of CLI take precedence over `default_cwd`
* Update docs for `default_cwd` and Launching Programs
Explains the `default_cwd` property more succinctly on the `Config` struct.
Adds documentation on the various ways to set the working directory and the logic used to decide the working directory.
wezterm sets a more restrictive umask (`0o077`) by default so that any files
that it creates (eg: unix domain socket, log files) are more secure
by default.
However, some environments rely on the more general default of (`0o022`)
without checking that it is set.
This matters because programs spawned by wezterm inherit its more
restricted umask.
I hadn't noticed this because I've had `umask 022` in my shell RC files
since sometime in the 1990's.
This commit adds some plumbing to the pty layer to specify an optional
umask for the child process, and some more to our umask saver helper
so that any thread can determine the saved umask without needing a
reference to the saver itself, which may be in a different crate.
The logic in the config crate has been adjusted to connect the saved
value to the default command builder arguments.
The net result of this is that running `wezterm -n start bash -- --norc`
and typing `umask` in the resultant window now prints `0022`.

I noticed that wezterm is picking up garbage from gnome too,
so let's trigger the random fd closing function on all unix
systems.
It turns out that iterating the entries in /dev/fd works on
BSD and Linux which is nice.
Needed to re-order a couple of things to match recent changes.
Also: don't hard fail if the ssh server rejects a setenv request,
just log the error instead.
Seems that you need to have read everything you want before you
call waitpid, otherwise the pending data seems to be snipped and
prevented from being read.

Since the last release we've migrated from failure -> anyhow,
added more functions to the command builder, improved windows
support and have compatibility with the `smol` crate.

This commit allows loading the console functions from `conpty.dll`
instead of `kernel32.dll` which means that we can update and
track newer features than have been deployed to Windows.
In practical terms this means that we can now unlock mouse input
reporting in eg: VIM running under WSL.

We're jumping the gun on this issue, which is tracking making
a proper supportable way to deploy this sort of update:

For now it seems easier just for us to bundle our own copy of
these bits.
This includes a speculative change to include those in our
Windows downloads also.
The binaries were built from
4f8acb4b9f
That version has the ability to use SSH agent forwarding.
This commit doesn't enable that functionality, it's just updating
the version and adjusting for changes in the upstream.
This is useful for setting up a reasonable initial environment.
For example, on Windows you might want to set the `prompt` environment
so that some basic shell integration is enabled; this will cause new
tabs to open with the same cwd as the current tab:
```
set_environment_variables = { "prompt"="$E]7;file://localhost/$P$E\\$P$G" }
```
This setting is intended to apply only to the local domain.
refs: https://github.com/wez/wezterm/issues/146
This allows this prompt setting to work:
```
prompt $E]7;file://localhost/$P$E\$P$G
```
although this one sets it for future prompts:
```
setx prompt $E]7;file://localhost/$P$E\$P$G
```

At some recent point in history, I effective broke multiple tabs in
`wezterm ssh HOST` by allowing them to contend in weird ways on locks,
leading to a horribly sluggish experience where multiple keypresses
in alternate tabs would appear to be swallowed until IO happened in
another tab. Yuk!
This commit fixes that up by teaching channels how to wait cooperatively
and to attempt a read in all waiting channels when the fd becomes
readable.
