039b640f6b 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.

05e0adaa01 screen operations operate on the active area
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.

9d26ab2dc8 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.
