Suggested by Stefan Monnier (Bug#21688).
* src/syntax.c (update_syntax_table_forward):
Remove recently-added PROPERTIZE arg, and assume it is true.
All callers changed.
* src/syntax.h (UPDATE_SYNTAX_TABLE_FORWARD_FAST):
Invoke update_syntax_table directly.

Problem reported by Ken Raeburn.
Solution suggested by Stefan Monnier (Bug#21688).
* src/regex.c (re_match_2_internal):
Use new _FAST functions to avoid regex code reentering itself.
* src/syntax.c (update_syntax_table_forward): New arg PROPERTIZE.
All callers changed.
* src/syntax.h (UPDATE_SYNTAX_TABLE_FORWARD_FAST)
(UPDATE_SYNTAX_TABLE_FAST): New inline functions.

Redo src/*.h so that each include file is idempotent (that is, can
be included multiple times with the latter inclusions having no
effect) and standalone (that is, can be included by itself,
with no include file other than config.h needed as a prerequisite).
This is standard practice in GNU programs nowadays.

syntax.h defined an extern inline function SYNTAX_ENTRY that was
conditionally compiled one way in some modules, and a different
way in others.  This doesn't work with extern inline functions,
which must have the same definition in all modules, because the
defining code might be shared across modules, depending on the
implementation.  Symptoms reported by Martin Rudalics in:
http://lists.gnu.org/archive/html/emacs-devel/2013-09/msg00414.html
* regex.c, syntax.c (SYNTAX_ENTRY_VIA_PROPERTY): Remove.
(SYNTAX, SYNTAX_ENTRY, SYNTAX_WITH_FLAGS): New macros,
overriding the corresponding functions in syntax.h.
* syntax.h (syntax_property_entry, syntax_property_with_flags)
(syntax_property): New inline functions.
(SYNTAX_ENTRY, SYNTAX_WITH_FLAGS, SYNTAX):
Rewrite in terms of these new functions.

* lib-src/profile.c (INLINE): New macro.
(SYSTIME_INLINE): Remove.
* src/conf_post.h (INLINE): Define only if not already defined.
This allows us to use a single INLINE, defined by one file
per executable.
* src/emacs.c (INLINE): Define it.
Also, include category.h, charset.h, composite.h, dispextern.h,
syntax.h, systime.h, so that their INLINE definitions are expanded
properly for Emacs.
