sattr_T was defined as uint16_t. But this is not enough to handle the
24-bit colors of the terminal. To solve this problem, change it to int.
In 32bit, int may overflow. So, if it overflows, change it to ignore it
without adding more attr_entries.

Problem: When Normal highlight group defines ctermfg/bg, but other
highlight group lacks ctermfg/bg, nvim_get_hl_by_id(hl_id,
v:false) returns -1 for the missing ctermfg/bg instead of just
omitting it.
Solution: checking for -1 in hlattrs2dict()
fix#11680
add proper msg_set_pos event, delet win_scroll_over_*
make compositor click through unfocusable grids
add MsgArea attribute for the message/cmdline area, and add docs and tests
Why?
- Because we can.
- Because the TUI is just another GUI™
- Because it looks kinda nice, and provides useful context like 1 out of 100
times
Complies with "don't pay for what you don't use".
Some crashes for resizing were unfolded, add tests for those.
Initially we will use this for the popupmenu, floating windows will
follow soon
NB: writedelay + compositor is weird, we need more flexible
redraw introspection.
Add ext_newgrid and ext_hlstate extensions. These use predefined
highlights and line-segment based updates, for efficiency and
simplicity.. The ext_hlstate extension in addition allows semantic
identification of builtin and syntax highlights.
Reimplement the old char-based updates in the remote UI layer, for
compatibility. For the moment, this is still the default. The bulitin
TUI uses the new line-based protocol.
cmdline uses curwin cursor position when ext_cmdline is active.
