~delthas/senpai-dev

v1->v2:
- [cc0] Fix Alt+BackSpace in parser
- Fix translation of certain C0 control keys

This series replaces tcell with a library I wrote called vaxis. It's got a
similar API and more features. Some specific ones that could be useful to
senpai:

- Image support (kitty, sixel)
- Proper grapheme segmentation detection and support (via DECMODE 2027)
- Mouse shapes (implemented in patch 2/2 in these series for changing the
  channel list width, so ridiculous but very cool)
- Curly underlines
- Kitty keyboard protocol

This is likely to have lots of bugs. I've been running it myself for quite
awhile, but the kitty keyboard protocol specifically can create a lot of bugs
with key matching, especially with non-us layouts. I've got a similar patch
series going with aerc and fixing lots of these bugs already, but I expect there
will be more.

There are two new packages brought in: vaxis and vaxis-tcell. Vaxis-tcell is
an implementation of a tcell "screen", using vaxis as the renderer, but exposing
the internals of vaxis so you can slowly bring in the vaxis types without
blowing up the entire UI code.

By no means do I expect this to be merged, this is a feeler for testing. The
goal I have with aerc (and would also do here) is to do a longer series using
the 'vaxis-tcell' package as a bridge to enable smaller commits, with the goal
being that by the end of the series 'vaxis-tcell' is no longer needed and the
entire application is using vaxis types everywhere.
