80d9be8122 Convert miscellaneous function definitions to prototype style.
This patch converts various miscellaneous functions definitions in
glibc, found with grep and not covered by my previous scripted
conversions, from old-style K&R to prototype-style.  These changes
were made manually.  This is not necessarily exhaustive as formatting
variants may have prevented my grep from finding some such
definitions.

Regarding the changes to files from GMP, they may originally have been
omitted when removing __STDC__ conditionals because of the files
coming from another package, but (a) GMP no longer has __STDC__
conditionals there anyway and (b) we don't try to keep these files
verbatim in sync with GMP (and there are licensing differences), so
making the change to them in glibc seems reasonable.

Tested for x86_64 and x86 (testsuite - this patch affects files
containing assertions).

9dd346ff43 Convert 113 more function definitions to prototype style (files with assertions).
This mostly automatically-generated patch converts 113 function
definitions in glibc from old-style K&R to prototype-style.  Following
my other recent such patches, this one deals with the case of function
definitions in files that either contain assertions or where grep
suggested they might contain assertions - and thus where it isn't
possible to use a simple object code comparison as a sanity check on
the correctness of the patch, because line numbers are changed.

A few such automatically-generated changes needed to be supplemented
by manual changes for the result to compile.  openat64 had a prototype
declaration with "..." but an old-style definition in
sysdeps/unix/sysv/linux/dl-openat64.c, and "..." needed adding to the
generated prototype in the definition (I've filed
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68024> for diagnosing
such cases in GCC; the old state was undefined behavior not requiring
a diagnostic, but one seems a good idea).  In addition, as Florian has
noted regparm attribute mismatches between declaration and definition
are only diagnosed for prototype definitions, and five functions
needed internal_function added to their definitions (in the case of
__pthread_mutex_cond_lock, via the macro definition of
__pthread_mutex_lock) to compile on i386.

After this patch is in, remaining old-style definitions are probably
most readily fixed manually before we can turn on
-Wold-style-definition for all builds.

Tested for x86_64 and x86 (testsuite).

2f44ee08db Fix regcomp wcscoll, wcscmp namespace (bug 18497).
regcomp brings in references to wcscoll, which isn't in all the
standards that contain regcomp.  In turn, wcscoll brings in references
to wcscmp, also not in all those standards.  This patch fixes this by
making those functions into weak aliases of __wcscoll and __wcscmp and
calling those names instead as needed.

Tested for x86_64 and x86 (testsuite, and that disassembly of
installed shared libraries is unchanged by the patch).

9dd6b7799a Fix regex wctype namespace (bug 18495).
regcomp brings in references to various wctype functions that aren't
in all the standards including regcomp.  This patch fixes this in the
usual way by using the __* versions of these functions (which already
exist, but some didn't have libc_hidden_proto / libc_hidden_def
before).

Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).  (Other wide character
function references from the regex code mean that this patch by itself
doesn't fix any XFAILed linknamespace test failures; further patches
will be needed for that.)

39a12f8db4 posix/regcomp: initialize union structure tag to avoid warning
We see some surprising warnings on tilegx with gcc 4.8.2:

In file included from regex.c:66:0:
regcomp.c: In function ‘parse_expression’:
regcomp.c:2849:15: error: ‘end_elem’ may be used uninitialized in this
function [-Werror=maybe-uninitialized]
       else if (br_elem->type == COLL_SYM)
               ^
regcomp.c:3109:34: note: ‘end_elem’ was declared here
       bracket_elem_t start_elem, end_elem;
                                  ^
regcomp.c:3109:22: error: ‘start_elem’ may be used uninitialized in
this function [-Werror=maybe-uninitialized]
       bracket_elem_t start_elem, end_elem;
                      ^

These warnings are not seen on x86, and in fact if I compile the
preprocessed tile sources with the x86 gcc 4.8.2, I don't see the
warnings.  I do see eqiuvalent warnings if I compile the
x86-preprocessed source code with tilegx gcc 4.8.2.

The fix here is to initialize the union type field appropriately in
a couple of places where we pass a union pointer to a subroutine that
"knows" what type the union is.  Setting the type explicitly seems like
a more robust way to manage such a data structure in any case.

815d8147a3 Fix ranges with multibyte characters as endpoints.
This is another bug in computing the fastmap.  It was reported by a user
of sed because it usually does not happen with !_LIBC.  However, it is
there in that case too.

The bug is that whenever we have a range at the beginning of the regex,
the regex must be tested on any possible multibyte character.  The reason
why _LIBC masks it, is that in general there is a collation symbol for
each possible multibyte-character lead byte, so all the lead bytes are
in general already part of the fastmap.

	[BZ #1302]
	Change bitset word type from unsigned int to unsigned long int,
	as this has better performance on typical 64-bit hosts.  Change
	bitset type name to bitset_t.
	* posix/regcomp.c (build_equiv_class, build_charclass):
	(build_range_exp, build_collating_symbol):
	Prefer bitset_t to re_bitset_ptr_t in prototypes, when the actual
	argument is a bitset.  This is merely a style issue, but it makes
	it clearer that an entire array is expected.
	(re_compile_fastmap_iter, init_dfa, init_word_char, optimize_subexps,
	lower_subexp): Adjust for new bitset_t definition.

	(BITSET_WORDS): Renamed from BITSET_UINTS.  All uses changed.
	(bitset_word_t): New type, replacing 'unsigned int' for bitset uses.
	All uses changed.
	(BITSET_WORD_MAX): New macro.
	(bitset_set, bitset_clear, bitset_contain, bitset_empty,
	(bitset_set_all, bitset_copy):  Adjust for bitset_t change.
	(bitset_empty, bitset_copy):
	Prefer sizeof (bitset_t) to multiplying it out ourselves.
	(bitset_not_merge): Remove; unused.
	(bitset_contain): Return bool, not unsigned int with one bit on.
	All callers changed.
	* posix/regexec.c (build_trtable): Don't assume bitset_t has no
	stricter alignment than re_node_set; do this by defining a new
	internal type struct dests_alloc and using it to allocate memory.
