Problem: popup: windows flicker when updating text
Solution: Only refresh the popup mask if the position or size changed,
manually set the window redraw type instead of using
redraw_win_later() to avoid triggering a full screen redraw.
Handle opacity 100 correctly. Keep "firstline" sticky when
setting options (Yasuhiro Matsumoto).

Problem: popup: flickering on opaque popups with overlapping text,
even if they are opaque (after v9.2.0016).
Solution: Prevent double redrawing by skipping background updates for
opaque popups. Revert changes to test dumps
(Javier Jaramago Fernández).
A flickering effect was introduced in commit v9.2.0016 (commit:
6c203072f) for all popups. This is a consequence of a double redraw of
the overlapping background characters. This could be expected for
transparent popups, but, it should exclude opaque ones. For a complete
fix of the flickering this commit is required in combination with fix
present in v9.2.0064 (commit: 97c5bed84b).
Additionally this commit reverts changes introduced for tests dumps for
masks in commits 6c203072f and cded5e220. These dumps were updated
preventing characters from popups to take into account the masks
specified for them. This forces the redraw of popup characters, even
when masks attempt to prevent them, leading to flickering effects. See
issues #19510 and PR: #19534.

Problem: close button "X" is visible in the non-GUI 'tabline', even

Solution: only show the button when 'mouse' contains any of the flags
"anvi" (Girish Palya)
The tabline always displays an "X" (close) button, and the info popup
shows both a close button and a resize handle—even when the mouse is
disabled. These UI elements are only actionable with the mouse and serve
no purpose for keyboard users who disable the mouse. Displaying
non-functional, clickable elements in a non-GUI environment is
misleading and adds unnecessary visual clutter.
So remove the close button and resize handle when the mouse is disabled.
They appear again when mouse is enabled.

This adds support for alternate font highlighting using CSI SGR 10-20.
Few terminals currently support this, but with added tool support this
should improve over time. The change here is more or less taken from how
colors are configured and applied, but there might be some parts I
missed while implementing it. Changing fonts is done through the new
`:hi ctermfont` attribute which takes a number, 0 is the normal font, and
the numbers 1-9 select an "alternative" font. Which fonts are in use is
up to the terminal.

Problem: statusline may look different than expected
Solution: do not check for highlighting of stl and stlnc characters
statusline fillchar may be different than expected
If the highlighting group for the statusline for the current window
|hl-StatusLine| or the non-current window |hl-StatusLineNC| are cleared
(or do not differ from each other), than Vim will use the hard-coded
fallback values '^' (for the non-current windows) or '=' (for the
current window). I believe this was done, to make sure the statusline
will always be visible and be distinguishable from the rest of the
window.
However, this may be unexpected, if a user explicitly defined those
fillchar characters just to notice that those values are then not used
by Vim.
So, let's assume users know what they are doing and just always return
the configured stl and stlnc values. And if they want the statusline to
be non-distinguishable from the rest of the window space, so be it. It
is their responsibility and Vim shall not know better what to use.

Problem: cannot complete option values
Solution: Add completion functions for several options
Add cmdline tab-completion for setting string options
Add tab-completion for setting string options on the cmdline using
`:set=` (along with `:set+=` and `:set-=`).
The existing tab completion for setting options currently only works
when nothing is typed yet, and it only fills in with the existing value,
e.g. when the user does `:set diffopt=<Tab>` it will be completed to
`set diffopt=internal,filler,closeoff` and nothing else. This isn't too
useful as a user usually wants auto-complete to suggest all the possible
values, such as 'iblank', or 'algorithm:patience'.
For set= and set+=, this adds a new optional callback function for each
option that can be invoked when doing completion. This allows for each
option to have control over how completion works. For example, in
'diffopt', it will suggest the default enumeration, but if `algorithm:`
is selected, it will further suggest different algorithm types like
'meyers' and 'patience'. When using set=, the existing option value will
be filled in as the first choice to preserve the existing behavior. When
using set+= this won't happen as it doesn't make sense.
For flag list options (e.g. 'mouse' and 'guioptions'), completion will
take into account existing typed values (and in the case of set+=, the
existing option value) to make sure it doesn't suggest duplicates.
For set-=, there is a new `ExpandSettingSubtract` function which will
handle flag list and comma-separated options smartly, by only suggesting
values that currently exist in the option.
Note that Vim has some existing code that adds special handling for
'filetype', 'syntax', and misc dir options like 'backupdir'. This change
preserves them as they already work, instead of converting to the new
callback API for each option.
