Test scenario is:
* Create a split
* in each pane run: `printf "\e[?1004h" ; od -c`
* Focus the panes, focus another window, and focus the window again
* The I and O events appear in the panes when changing their focus.
* Previously, only the active pane would get focus events when the
window focus changed.

* [terminfo] add smxx/rmxx, purge blink
Testing with WezTerm nightly indicates no blink support
available through the xterm \E[5m, and I didn't see any
support in the code -- purge it. smxx and rmxx, meanwhile,
have been added to indicate support for struck text.
* restore blink

Test scenario is `cat`ing the public domain wiki text data from
http://cs.fit.edu/~mmahoney/compression/enwik8.zip in the terminal;
that file is 96M in size.
`time cat ~/Downloads/enwik8.wiki`
Prior to this change, depending on the OS, the time to cat the file
could be several minutes.
Digging in, the bottleneck appears to be that there isn't sufficient
parallelism between the reader and the parser, which means that the
rate of reading data is constrained by how long it takes to parse
and render a frame.
This commit switches away from using a synchronized vecdeque to
effectively create a non-blocking pipe, to "simply" using a socketpair
with a larger buffer size.
We now do blocking pty read -> write to socketpair in the reader
thread, and then read socketpair -> parse in the other.
The key difference between before and after being that the pty read
can continue to read and accumulate data (with an upper bound, so
that CTRL-C is still responsive) while we're parsing and rendering
a frame.
This increases the throughput for this scenario, bringing it down
from ~3:30 to ~17 seconds on this Ryzen 2700X system.

I added this originally thinking that it would make it easier to resolve
https://github.com/wez/wezterm/issues/695 and to integrate wgpu support,
but it's the cause of https://github.com/wez/wezterm/issues/922 so let's
take it out and more directly connect the window events to those in the
terminal.
This commit likely breaks mac and windows; pushing it so that I can
check it out and verify on those systems.
The common palette indices are in the main cell attributes.
Using true color will allocate fat storage.
This allows reducing the Cell size from 32 -> 24 across the
implementation of storing 10 bpc color (it peaked at 40 in
the last couple of commits).
Adding an edge from wezterm-ssh -> async_ossl causes the
openssl vendoring feature selection logic to trigger, which
in turn allows `cargo build -p window --examples` to succeed
again on macos.
0.8 doesn't seem to build with rusttls, but I don't think
we need that any more: we've been using vendored openssl on windows
and mac for some time.

opentype allows a font to have a weight in the range 0-1000.
MacOS has its own concept of symbolic weight names and opentype
values that is a slightly different scale of boldness to Windows
and Linux.
That means that Medium could be a different range of opentype
weight values depending on the system.
To further complicate things, the font designer can name their
variant with any name they like and assign it an arbitrary
opentype weight value.
For the Operator Mono font, it has Book variant with opentype
weight 325 and a Light variant with an opentype weight of 300.
wezterm was considering these both to have `FontWeight::Light` because
that's how those values were bucketed, which results in amibiguity in
resolve the font and frustration in not being able to access one of the
variants.
This commit changes the `FontWeight` type to now hold the unambiguous
opentype weight value, and to define some symbolic aliases for
some specified weights.
When serializing, if the weight matches a symbolic alias, then that
name will be used in the canonical name (eg: as listed via ls-fonts).
Otherwise, the numeric value will be used.
When parsing the font configuration, wezterm will allow both symbolic
and numeric values.
This allows all of the Operator Mono variants to be referenced
unambiguously, although some variants have to be specified via the
numeric weight:
```
wezterm.font("Operator Mono", {weight=275, stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-XLight.otf, FontDirs
wezterm.font("Operator Mono", {weight="Light", stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-Light.otf, FontDirs
wezterm.font("Operator Mono", {weight=325, stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-Book.otf, FontDirs
wezterm.font("Operator Mono", {weight="DemiLight", stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-Medium.otf, FontDirs
wezterm.font("Operator Mono", {weight="Regular", stretch="Normal", italic=false}) -- /Users/wez/.fonts/OperatorMono-Bold.otf, FontDirs
```
