* lisp/progmodes/cc-fonts.el (gtkdoc-font-lock-keywords): Amend the regexp
recognizing the introductory "/**" to allow subsequent characters on that
line.
This is because these variables are needed at runtime even when cc-fonts.el
hasn't been loaded, as in XEmacs when font locking hasn't been enabled.

(c-doc-bright-comment-start-re, c-doc-line-join-end-ch): Move definitions to

c-lineup-class-decl-init-after-brace.

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

evaluate an argument only once at runtime.
String delimiters, including escaped new lines, of correctly terminated
strings are left in font-lock-string-face. All others get
font-lock-warning-face. The latter get syntax-table text properties on the
opening string delim and the "terminating EOL".

(c-after-change-re-mark-unbalanced-strings): New functions.
(c-after-change): Fix a bug with the handling of c-just-done-before-change.
* lisp/progmodes/cc-engine.el (c-inside-bracelist-p): Return a bufpos rather
than t for the enum case.
(c-add-stmt-syntax, c-guess-continued-construct): Replace
c-looking-at-or-maybe-in-bracelist by c-inside-bracelist-p, since the former
does not recognize enum brace lists, but the latter does.
* lisp/progmodes/cc-fonts.el (c-get-fontification-context): Replace
c-looking-at-or-maybe-in-bracelist by c-inside-bracelist-p.
* lisp/progmodes/cc-fonts.el (c-font-lock-doc-comments): Take into account
the possibility of font-lock-comment-delimiter-face. Test rigorously for
"/**" (etc.) being itself inside a literal, rather than just depending on the
face of the previous character.
Also recognize and handle function names introduced by "extern" inside a
function.
* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): Add a new element to
the result list which is t when our declaration is, or is to be treated as,
being at top level.
* lisp/progmodes/cc-fonts.el (c-get-fontification-context): Detect being
inside a C++ uniform initialization and return (not-decl nil) for this case.
(c-font-lock-declarations): Use the new element 4 of the result of
c-forward-decl-or-cast-1.
* lisp/progmodes/cc-langs.el (c-make-top-level-kwds, c-make-top-level-key):
New lang consts/vars.
This fixes (a follow-up to) bug #28850.
A internal generated form for scanning text to fontify had a LIMIT parameter.
It also locally bound LIMIT to a value possibly beyond the original LIMIT,
allowing point to move beyond the original LIMIT, and to create the wrong side
error. Fix it by checking point is not beyond LIMIT in the outer context
before using it.
* lisp/progmodes/cc-fonts.el (c-make-font-lock-search-form): Add a new
parameter CHECK-POINT which, when non-nil, directs the function to generate a
check on point.
(c-make-font-lock-context-search-function): Invoke the above function with new
argument value t.
The cause was a scanning over a bracket pair taking us beyond the supplied
LIMIT parameter in c-forward-declarator.
* lisp/progmodes/cc-engine.el (c-forward-declarator): Add three checks (<
(point) limit) whilst dealing with tokens after the declared identifier.
* lisp/progmodes/cc-fonts.el (c-font-lock-declarators): Don't supply a LIMIT
argument to `c-forward-declarator' (twice), since we want to fontify up till
the end of a declarator, not an arbitrary jit-lock chunk end.
Use the new function directly in several places where c-forward-token-2
wouldn't move over the last token in the buffer. This caused an infinite loop
in c-restore-<>-properties.
* lisp/progmodes/cc-engine.el (c-forward-over-token-and-ws): New function,
extracted from c-forward-token-2.
(c-forward-token-2): Refactor, calling the new function.
(c-restore-<>-properties): Fix infinite loop.
(c-forward-<>-arglist-recur, c-in-knr-argdecl)
(c-looking-at-or-maybe-in-bracelist): Call the new function directly in place
of c-forward-token-2.
* lisp/progmodes/cc-cmds.el (c-defun-name) Call the new function directly in
place of c-forward-token-2.
* lisp/progmodes/cc-fonts.el (c-font-lock-enclosing-decls): Call the new
function directly in place of c-forward-token-2.
* lisp/progmodes/cc-fonts.el (c-font-lock-declarators): Introduce a new
optional parameter, template-class. In "class <X = Y>", fontify "Y" as a
type.
(c-font-lock-single-decl): New variable template-class, set to non-nil when we
have a construct like the above. Pass this as argument to
c-font-lock-declarators.
(c-font-lock-cut-off-declarators): Check more rigorously that a declaration
being processed starts before the function's starting position.
(c-complex-decl-matchers): Remove the redundant clause which fontified "types
preceded by, e.g., "struct"".
* lisp/progmodes/cc-langs.el (c-template-typename-kwds)
(c-template-typename-key): New lang defconsts and defvar.
