When the screen is cleared/reset, the physical top is not reset with it,
instead the scrollback_top variable gets set with the point at which the
screen was reset / you are allowed to scroll back to. The scroll bar
code wasn't aware of that.

Looking closer, I think I'd misread the key event generated by
perform_key_equivalent for the ctrl-escape case as a key down.
Fixing this is fairly straightforward: when we return YES from
perform_key_equivalent we synthesize a key_down event.
macos will follow up with the key up.
We can fold two cases together in there and remove the horrible
hack style fix I just added in a4b68247bb

We want to avoid normalizing control key presses; there were
two places where it was happening; one in our own code and
the other was in the xkeyboard mapping stuff itself.

checkout seems to be failing for ubuntu 20 recently:
```
Deleting the contents of '/__w/wezterm/wezterm'
Initializing the repository
/usr/bin/git init /__w/wezterm/wezterm
Initialized empty Git repository in /__w/wezterm/wezterm/.git/
/usr/bin/git remote add origin https://github.com/wez/wezterm
Error: fatal: unsafe repository ('/__w/wezterm/wezterm' is owned by someone else)
To add an exception for this directory, call:
git config --global --add safe.directory /__w/wezterm/wezterm
Error: The process '/usr/bin/git' failed with exit code 128
```
Try reverting this as a workaround.
There are certain key combinations that macOS prefers to handle
without giving the application much opportunity to process them.
CTRL-ESC and CMD-. both cause doCommandBySelector(cancel:) to be
called. The former we had already special cased but since we
can't disambiguate the two things, we need a better way.
performKeyEquivalent: is a method we can implement to have an
opportunity to "do something" and prevent the default macOS behavior.
So we implement that. What's interesting is that saying that we handled
CMD-. results in no further processing at all by macOS, whereas saying
that we handled CTRL-ESC results in macOS doing the normal key event
dispatch. So we need to route that event for ourselves in that one
case.
Doesn't feel great!

Use some heuristics to verify the data that is about to be parsed;
this can help to detect eg: data being output to stdout prior
to us sending any encoded data to the remote mux.
In addition, add a timeout to help avoid waiting forever in
the case that we didn't detect a problem.

I'm not totally sure this is all there is to it, but in #1850
the response is showing up after vim was exited, so it seems like
it didn't fully receive these responses.

Create a list of command definitions to hold the default key
assignments.
That list has more metadata, such as a brief and longer human
readable description of the purpose, and allows for (in the
future) reasoning about the context where the command is valid,
as well as providing more information when rendering in the
launcher menu.
