bba9757 Backport: Fix an assignment to free variable warning

Rework face hints for partial-string completion styles

Don't use completions-first-difference for the 'substring', 'flex' and
'partial-completion' styles, since there can be really no reasonable
definition of a "first" difference there.

Make completions-common-part inherit from 'underline' so that it is
useful by default for all completion styles.

* lisp/minibuffer.el (completions-common-part): Adjust
description and change default value.
(completions-first-difference): Ajust docstring.
(completion-pcm--hilit-commonality): Don't use
completions-first-difference.

Allow completion styles to adjust completion metadata

This commit re-does the now-reverted commit with the same title.  That
version relied on generic functions, which cannot be used yet in files
such as lisp/minibuffer.el.  This version uses a symbol property
completion--adjust-metadata instead.

The new facility allows completion styles to have a say in metadata
properties such as cycle-sort-function and display-sort-function.
This is especially useful for completion styles such as 'flex', which
generally produce many matches, including some potentially "obscure"
ones.  The default sorting strategy would often bubble the latter to
the top of the list.

The sorting function for 'flex' considers pre-computed matching scores
and is thus much better than the default for this particular style.

Additionally, it overrides the completion table's cycle-sort-function
or display-sort-function properties if they exist, although it still
uses them to pre-sort the result, so that they are still relevant for
resolving ties.

* lisp/minibuffer.el (completion--nth-completion)
(completion--flex-adjust-metadata): New helper.
(flex): Put completion--adjust-metadata property.

Revert "Allow completion styles to adjust completion metadata"

Unbreaks the build.

This reverts commit 7fc0292f5c49d11fc39853f8bc25586d54221e6a.

Unfortunately, cl-defgeneric has some problems when used in
lisp/minibuffer.el.

subr.el (run-window-configuration-change-hook): Mark obsolete

Allow completion styles to adjust completion metadata

The new facility, realized in the completion-adjust-metadata-for-style
generic, allows completion styles to have a say in metadata properties
such as cycle-sort-function and display-sort-function.  This is
especially useful for completion styles such as 'flex', which
generally produce many matches, including some potentially "obscure"
ones.  The default sorting strategy would often bubble the latter
to the top of the list.

The sorting function for 'flex' considers pre-computed matching scores
and is thus much better than the default for this particular style.

Additionally, it overrides the completion table's cycle-sort-function
or display-sort-function properties if they exist, although it still
uses them to pre-sort the result, so that they are still relevant for
resolving ties.

* lisp/minibuffer.el (completion--nth-completion): Call
completion-adjust-metadata-for-style.
(completion-adjust-metadata-for-style): New generic.
(completion-adjust-metadata-for-style 'flex): New method.

Replay key if kboard is interrupted while initializing (Bug#37782)

The problem with the original fix for bug#5095 is that it drops
the current event, which is a valid character event and not -2.
Thus, the first ESC character sent by the terminal after turning
on focus tracking is lost and we get '[' and 'I' events separately
inserted into the buffer afterwards.

* src/keyboard.c (read_key_sequence): Add key as mock_input and replay
sequence using new keyboard, when the key is not -2.

Remove redundant initialization of fringe bitmap (Bug#37756)

* src/fringe.c (Fdefine-fringe-bitmap): Remove redundant zeroing
of fb.bits that only zeroed half of the array anyway.

Improve the documentation of 'vc-tor'

* lisp/vc/vc-dispatcher.el (vc-tor): Add :version.  Enhance
the doc string.

* etc/NEWS: Announce the new option.

Adapt doc-view to latest image-mode changes

The functions image-scroll-down, image-scroll-up, image-next-line, and

character height as of commit 9c66b09950.

* lisp/progmodes/cc-cmds.el (c-guess-fill-prefix): When determining a new
