terminal: Fix potential invalid local 'scrollback' (#9605) 
TermOpen autocmd may set local 'scrollback' to -1, this needs to be
adjusted as in on_scrollback_option_changed().

ee21fe3d2a TUI: force italics in tmux 
tmux users are encouraged to use "tmux-256color" instead of the old
"screen-256color". Put this in your .tmux.conf :

    if-shell 'infocmp tmux-256color' 'set -g default-terminal "tmux-256color"' 'set -g default-terminal "screen-256color"'

If default-terminal is "tmux-256color" AND tmux finds its terminfo, THEN
it will enable italics (regardless of whether the terminfo contains
sitm/ritm).

OTHERWISE tmux "emulates screen", which means it emits italics as
"reverse". That's unfortunate, but it's an acceptable compromise that
allows Nvim to support italics in tmux by default in compatible (and
increasingly-common) configurations.

Test case:

    tmux
    nvim -u NORC +'hi Comment cterm=italic' CMakeLists.txt

2beb731ed4 TUI: italics in Terminal.app (nsterm) 
This is the conservative approach, requiring TERM=nsterm as recommended
at `:help $TERM`.  It won't work with Terminal.app's default of
TERM=xterm-256color, nor in tmux.

Test case:

    TERM=nsterm nvim -u NORC +'hi Comment cterm=italic' CMakeLists.txt

891ed14f13 api: add nvim_create_buf to create a new empty buffer. 
Loading existing files into a buffer is non-trivial and requires a window.
Creating an unnamed emtpy buffer is trivial and safe though, thus worth a
special case.

Change nvim_buf_set_option to use aucmd_prepbuf. This is necessary
to allow some options to be set on a not yet displayed buffer, such
as 'buftype' option.

be8058cfe4 screen: cleanup allocation, clearing and validation 
grid_xx functions shouldn't randomly be called when the screen is not valid.
Nvim deterministically initializes a default screen early in main(), so the
default grid can be assumed to be allocated.

37f8df8824 UI: implement 'pumblend' option for semi-transparent popupmenu 
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.

91688b4883 options: set 'scrollback' to -1 by default #9563 
Makes the 'scrollback' option more consistent (same default for all buffers) and future-proof.

- Default to -1 for all buffers, but treat it as an implementation detail.
- Document range of 1 - 100_000.
- New terminal buffer by default sets scrollback=10_000 if the global default is -1.
- Existing terminal buffer: On entering terminal-mode or on refresh, if the user explicitly did `:set[local] scbk=-1`, the local value goes to 100_000 (max). (This is undocumented on purpose. Users should work with explicit values in the range of 1-100_000.)
