This allows setting up shortcuts relative to the final tab in
a window, rather than always being relative to the first.
The default assignment for CTRL+SHIFT+9 is now `ActivateTab=-1`
as a convenient way to always reach the last tab.

We were unconditionally adding the encoded form of the modifier
mask (eg: appending `;1~` to the sequence) and not all apps know
how to interpret that.

While testing this with esctest, it was apparent that xterm deviates
from the DEC docs by allowing a minimum region size smaller than 2,
so adjust our restriction accordingly.
Now that we're reporting a higher level from DA1, apps are asking
more exotic codes. eg: vttest now asks about the conformance level,
but doesn't have a timeout on that request and hangs if we don't
respond.
This commit adds a bit of plumbing to make it easier to consume
and parse DCS sequences that are known to be short/short-lived,
and teaches the term layer to respond to a couple of possible
DECRQSS queries.
This is an xterm sequence that adjusts how the terminal
encodes keyboard output.
This commit teaches termwiz to parse and encode the sequence,
but doesn't teach the terminal emulator to do anything with it
at this time.
I'm adding this because vim sends these sequences and I wanted
to understand what they were for.
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.
We weren't parsing `CSI 2H`; we'd decide that because it needed two
parameters it was an error instead of defaulting the omitted second
parameter to 1.
With this commit, we now survive a reinstall or upgrade of the nvidia
drivers on my Windows sytem without crashing.
This commit allows notifying the application of the context loss
so the application can either try to reinit opengl or open a new
window as a replacement and init opengl there.
I've not had success at reinitializing opengl after a driver upgrade;
it seems to be persistently stuck in a state where it fails to allocate
a vertex buffer.
SO, the state we have now is that we try to reinit opengl on a new
window, and if that fails, leave it set to the software renderer.
This isn't a perfect UX, but it is better than terminating!

I don't have a great way to test this on those platforms,
so other than compiling and running and verifying that things
work normally, I'm not sure if this is sufficient!
This commit allows distinguishing between left and right alt
modifiers at the window layer. So far only macos provides
this additional information.
Expand the logic that decides whether Alt should emit the
composed key or act as the raw key with the Alt modifier flag
set so that we can set that behavior separately for the left
and right modifiers on systems that support it, and use the
existing config for systems that don't support it.
The default settings for these flags is that Left Alt will
send the uncomposed key + Alt modifier while the Right Alt
will behave more like AltGr (which is typically on the RHS
of the keyboard) and send the composed key.
This gives more flexibility by default and hopefully matches
expectations a bit better.
