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!

This was originally intended to be swept in and dealt with as part of
adopting CSI-u (refs: https://github.com/wez/wezterm/issues/63) but the
default shift-space mapping is super irritating in vim (refs:
https://github.com/wez/wezterm/issues/126) so it got partially walked
back, but as a consequence we accidentally dropped the modifiers from
those keys (refs: https://github.com/wez/wezterm/issues/213 refs:
https://github.com/wez/wezterm/issues/214).
This commit restores the modifiers for that case.
In addition, since we now have a way to plumb configuration directly
into the term crate, this adds a config option to enable CSI-u for those
that want to use it.
If the image is smaller than the cell size we could end up
rounding that dimension to zero and ultimately not render
the texture to the cell.
This commit adjusts the math to round up, which yields
better results for the test in refs: https://github.com/wez/wezterm/issues/211
I noticed that we still weren't quite right.
I think the net change is really just that we must force
the use of the CSI representation when using CTRL/SHIFT
modifiers.

We were treating DECCKM as the sole thing to enable application
cursor reporting, but looking closely at the docs, that mode only
takes effect when both DECANM (Vt52 emulation mode) AND DECKPAM
(application keypad mode) are both active.
neovim enables DECCKM and DECKPAM but not DECANM.

Bound to CMD-K and CTRL+SHIFT-K by default. This also functions
while the output is filling up (eg: `find /` and hit the key binding
to keep pruning the scrollback).

The click/movement related events are now "table driven" with
defaults contained in the InputMap object.
This gives the the potential to be configured from the config
file, but there is not glue in the config layer to enable
this yet.
This also does not include mouse wheel events.
neovim will try to force the window to resize after suspend/resume.
No other terminal allows this today, so rather than log it as an
unhandled event, explicitly ignore it.
This was a bit of a pain to track down because this behavior
isn't specified anywhere or called out explicitly.
The issue is that if you use a true color escape sequence such as
```bash
printf "\x1b[38;2;255;100;0mTRUECOLOR\n"
```
the active color would remain active when switching between the
primary and the alt screen until something (eg: `ls --color`) changed
it again.
I hadn't run into this because in my prompt, many many years ago, I had
it set to perform an SGR reset (`\x1b[0m`) as the first thing to ensure
that the shell is in a saner state.
For users that don't do this they end up with a weird looking color
bleed effect.

The predictive echo feels pretty reasonable, but if the connection
is having problems and we're showing the tardiness indicator, the
echo can give the impression that your input is going to get processed.
That may not be (usually is not!) the case.
This commit makes it a bit more visually distinctive that something
isn't right by greying out the color palette in that case.

Matching against the current dir when it includes a host and a
path seems like a handy way to automate selecting appropriate
theme/color/profile settings, so I'd like to make sure that
we have the full URL content available for that.

The rewrap logic makes dealing with the cursor position a bit
more complex and we had a problem where resizing the window shorter
and then taller would allow the shell to cursor up into the scrollback
when displaying its prompt, and allow it to overwrite something that
was logically in the scrollback.
