Removes the callbacks type and replaces event dispatch with
an async capable channel.
This makes it a bit simpler to model some of the window internals,
and to prepare for a wgpu enabled future.
This changes have been tested only on linux so far.
Adds a `ShowDebugOverlay` key assignment that will create a tab
overlay that shows a limited number of recently logged events.

The intent is to reveal more context on what's happening in
https://github.com/wez/wezterm/issues/671
As a nice side benefit, this avoids the potential inability
to open paths that are not utf8 or representable as c-strings
on Windows.
And on top of that: this enables memory mapped file IO as well,
which wasn't enabled previously. This should help to reduce
extraneous copies of the font in memory, have fewer open files
and minimize the chances of racing with O_CLOEXEC.
Replaces the last usage of ttf-parser with calling into freetype.
This removes a source of inconsistency, as ttf-parser doesn't support
all of the things that freetype does.
Notably, this prevents a weird error from blowing up codepoint coverage
calculations on a system where I have helvetica.bdf in my font dir for
long-forgotten reasons.
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

I can't get this to succeed though; I suspect there may be a lingering
bug from libssh2 and/or trailing support for newer openssh features.

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.

Rust 1.51 allows addressesing a long-standing TODO which was that we
shouldn't need to build a vendored copy of openssl on most sensible unix
systems.
We do require a vendored copy on macOS and Windows, but due to the way
that Cargo's feature resolver worked, it wasn't possible for this
requirement to be respected.
Rust 1.51 introduces `resolver="2"` which can deal with this feature
resolution!
https://doc.rust-lang.org/nightly/cargo/reference/features.html#feature-resolver-version-2
The upshot of this is that building wezterm on real unix systems that
are not macos will now link against the system libssl, resulting in both
a shorter compile time and less headaches arising from having a slightly
different openssl used by wezterm than the rest of the system.

There's something fishy with colorspaces and blending.
This commit removes the `window::Color` type and replaces
it and the confusing array of color types exposed by the
`palette` crate with a pair of much simpler types:
`LinearRgb` - a tuple of f32 linear color components
`SrgbaPixel` - the u32 sRGBA pixel representation
This doesn't change anything about rendering, it just
makes it a bit simpler and makes the SrgbaPixel -> LinearRgb
conversion happen slightly earlier which shaves off some
ad-hoc conversions.

CI got broken by the termwiz release. This commit teaches the
various `git describe --tags` calls to filter to the wezterm
tags which all start with the year. We're match `20*` which should
be good for the next 79 years.
I've removed the vergen dependency as there was no way to teach it
to do the equivalent matching, and it wasn't a terrible burden
to just inline the git describe call anyway.
Using a boxed slice means that we hold exactly the memory required
for the file data, rather than the next-power-of-two, which can
be wasteful when a large number of images are being sent to
the terminal.
This is a API breaking change for termwiz, so bump its version.
