screen: cache history offset
...
This is a super hot calculation so taking up memory to cache it resulted
in 15m less function calls when catting a 10mb file, and ~5% speedup.

Merge branch 'reflow'
...
This actually doesn't implement reflow but I wanted to merge this
because it has an important refactor and clarity around screen
operations.
It is now clearly defined in the API what portion of the screen you're
accessing (active, viewport, etc.) and the terminal only operates on the
active area (fixing TODO item in diff).
This is all groundwork I found was necessary to even start thinking
about reflow.

This fixes tons of bugs around escape sequences while scrolling that
used to work on the offset from the viewport (which is wrong). This now
calculates the actual active area and does that. This also fixes the
TODO in the diff.

memset zero values when resizing a screen
...
Zig safety checks save us! It was setting undefined values to `0xAA` and
we caught that in a crash. We need to zero this memory.
Practically this happened when `cat`-ing a large file, then attempting
to select and copy any blank trailing space.
