Partially revert the commits from 2021-10-24 - 2021-10-26, "CC Mode: Fontify
"found types" which are recognized after being first scanned".
This removes the background fontification which ran off of a 0.1s timer, but
leaves the facility of normal fontification causing the fontification
throughout the buffer of newly found types.
* lisp/progmodes/cc-fonts.el (c-find-types-background)
(c-type-finder-timer-func): Remove.
* lisp/progmodes/cc-mode.el (c-type-finder-timer, c-inhibit-type-finder)
(c-type-finder-pos, c-post-gc-hook): Remove.
(c-leave-cc-mode-mode): Remove the manipulations of c-type-finder-timer and
c-post-gc-hook.
(c-basic-common-init): Remove the manipulations of c-type-finder-pos,
c-type-finder-timer, and c-post-gc-hook.
* lisp/progmodes/cc-vars.el (c-type-finder-time-slot)
(c-type-finder-repeat-time, c-type-finder-chunk-size): Remove.
* doc/misc/cc-mode.texi (Found Types): Remove. Amend some menu entries.
This aims to fix the scenario where on jit-lock's first scan of a type, it is
not recognized as such, and only later does this happen. The fontification of
such found types is now done by background scanning in short time slices
immediately after initialising the mode.
* lisp/progmodes/cc-engine.el (c-add-type-1): New function.
(c-add-type): Extract c-add-type-1 from it, and reformulate the mechanism for
protecting c-found-types from excessive partial identifiers.

code which cleared c-found-types on fontification at BOB.

(c-before-change): Add code to clear c-found-types on a buffer change at BOB.

identifiers.

This mostly changes http: to https: in URLs. It also updates
some URLs that have moved, removes some URLs that no longer
work, recommends against using procmail (procmail.org no
longer works), and removes some mentions of the
no-longer-existing Gmane, LPF and VTW.
It doesn't update all URLs, just the ones I had time for.

"stroustrup", "python", and "java", change the offset for brace-list-intro

brace-list-entry from c-lineup-under-anchor back to 0.
* doc/misc/cc-mode.texi (top level): Using txicommandconditionals to

separate version of an item list structure for this version, simplifying it
considerably.
This happened because of false @c's in macro lines.

Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.
Also (unrelated change) initialize the modes' keymaps at each loading.

on the modeline.

(pike-mode-map, awk-mode-map): Make entries in these key maps each time the
mode is loaded rather than just once per Emacs session.
* doc/misc/cc-mode.texi (Comment Commands): Introduce the notion of comment
style.
(Minor Modes): Define comment style. Describe how comment style influences
the information displayed on the modeline. Document c-toggle-comment-style.

Also implement the "asymmetric space" rule for fontifying otherwise
ambiguous
declarations/expressions.

space" rule.

make `context' 'decl for lines contained within parens when these are also
declarations.

invocation of c-on-identifier with a check we're not at the _end_ of an
identifier.

perl versions of texi2dvi haven't implemented it.
(Syntactic Symbols): Note that `inlambda' is also used in C++ Mode, not just
in Pike Mode.
(Statement Block Symbols): Add a section illustrating a C++ lambda function.
(FAQ): Add a question about "excessive" indentation of the contents of a C++
lambda function, and how to get rid of it.
This fixes bug #24431. The key change of this bug fix is correctly analyzing
nested brace lists when the opening element stands on the same line as both
its introductory brace and an enclosing parameter list parenthesis.
* list/progmodes/cc-align.el (c-lineup-under-anchor): New line-up function.
* list/progmodes/cc-engine.el (c-looking-at-or-maybe-in-bracelist): Accept the
presence of exactly an identifier between an open parenthesis and an open

when needed.
(c-looking-at-inexpr-block): Extract new function (see above) and call it.

prime syntactic symbol with a fixed anchor point. When this is used, restrict
all added syntactic symbols to those having an anchor point on the same line.
Add, in addition to the current additional symbols, c-brace-list-entry when
needed; use c-looking-at-statement-block to determine the latter.
(c-guess-basic-syntax, CASE 9D): Use c-add-stmt-syntax rather than just
c-add-syntax, to assemble the syntactic context of a 'brace-list-entry, thus
getting, possibly, several accompanying syntactic entries.
* lisp/progmodes/cc-styles.el (c-style-alist, "gnu" style): New entry for
'brace-list-intro, namely c-lineup-arglist-intro-after-paren.
* lisp/progmodes/cc-vars.el (c-offsets-alist): Change the factory default
offset for 'brace-list-entry from 0 to c-lineup-under-anchor.
* doc/misc/cc-mode.texi (Syntactic Symbols): Amend the definition of
brace-list-intro.
(Brace List Symbols): Amend the example to show the new analysis of brace
lists when the first element comes on the same line as the opening brace.
(Misc Line-Up): Document the new line-up function c-lineup-under-anchor.
