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.
Previously, we'd require boxing the entire DCS representation
in the escape sequence parser. This was due to some clippy
advice that made sense at the time, but now that I'm looking
at more things using DCS it seems wasteful to Box each byte of
the dcs sequence. This commit shifts the box to the heavier
weight portion: the DCS hook/entry representation.
When processing `\033[?1002;1003;1005;1006h`, when we encountered
`1005` we would skip 1006. This was because we hit the unspecified
enum case for 1005 (we have no enum variant for that mode) and that
code path didn't properly advance only by a single position.
This commit fixes that.

This corrects an issue where the mode byte of the DCS sequence was
discarded from the DcsHook, making it impossible to know what sequence
is being activated.
So far this hasn't come up as these sequences are relatively rare,
but in looking at sixel parsing I noticed the error.
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
This is untested beyond eyeballing the locally generated file.
Will need to make a couple of tags to test this for sure.

I noticed a busy period when closing the connui when it is performing
the sleep with progress bar stage; returning from the function when
the channel disconnects seems like the right call.
I also made the loop slightly more efficient by only repainting if
the line has changed.
I don't really like this as a solution, however: I'd rather
spend time transitioning towards async IO for this instead of
troubleshooting further here.
