<locale.h> is specified to define locale_t in POSIX.1-2008, and so are
all of the headers that define functions that take locale_t arguments.
Under _GNU_SOURCE, the additional headers that define such functions
have also always defined locale_t. Therefore, there is no need to use
__locale_t in public function prototypes, nor in any internal code.

Change all uses of __locale_t to locale_t.

xlocale.h is already a single-type micro-header, defining struct
__locale_struct and the typedefs __locale_t and locale_t. This patch
brings it into the bits/types/ scheme: there are now
bits/types/__locale_t.h which defines only __locale_struct and
__locale_t, and bits/types/locale_t.h which defines locale_t as well
as the other two. None of *our* headers need __locale_t.h, but it
appears to me that libstdc++ could make use of it.
There are a lot of external uses of xlocale.h, but all the uses I
checked had an autoconf test or equivalent for its existence. It has
never been available from other C libraries, and it has always
contained a comment reading "This file is not standardized, don't rely
on it, it can go away without warning" so I think dropping it is
pretty safe.
I also took the opportunity to clean up comments in various public
header files that still talk about the *_l interfaces as though they
were completely nonstandard. There are a few of them, notably the
strtoX_l and wcstoX_l families, that haven't been standardized, but
the bulk are in POSIX.1-2008.
* locale/xlocale.h: Rename to...
* locale/bits/types/__locale_t.h: ...here. Adjust commentary.
Only define struct __locale_struct and __locale_t, not locale_t.
* locale/bits/types/locale_t.h: New file; define locale_t here.

Remove one more string inline that was defined directly in string.h;
in the absence of the rest of the inlines, it broke the build.
Like other ifunc shims for these functions,
x86_64/multiarch/{mem,st}pcpy.c need to define __NO_STRING_INLINES and
NO_MEMPCPY_STPCPY_REDIRECT.
* string/string.h (__mempcpy_inline): Delete.

* sysdeps/x86_64/multiarch/stpcpy.c:
Define NO_MEMPCPY_STPCPY_REDIRECT and __NO_STRING_INLINES
before including string.h.

These machine-dependent inline string functions have never been on by
default, and even if they were a good idea at the time they were
introduced, they haven't really been touched in ten to fifteen years
and probably aren't a good idea on current-gen processors. Current
thinking is that this class of optimization is best left to the
compiler.

There is no longer a need for string2.h, so remove it and all mention of it.
Move the redirect for __stpcpy to include/string.h since it is still required
until all internal uses have been renamed.

glibc headers include some code (not particularly consistent or
systematic) to put various declarations in C++ namespaces std and
__c99, if _GLIBCPP_USE_NAMESPACES is defined.
As noted in <https://gcc.gnu.org/ml/libstdc++/2017-03/msg00025.html>,
this macro was removed from libstdc++ in 2000. I don't expect
compilation with such old versions of libstdc++ to work with current
glibc headers anyway (whereas old *binaries* are expected to stay
working with current glibc); this patch (which should be a no-op with
any libstdc++ version postdating that removal) removes all this code
from the glibc headers.
The begin-end-check.pl test, whose comments say it is about checking
these namespace macro calls, is also removed. The code in that test
would have covered __BEGIN_DECLS / __END_DECLS as well, but if those
weren't properly matched it would show up with the
check-installed-headers-cxx tests, so I don't think there is an actual
use for keeping begin-end-check.pl with the namespace code removed.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

explicit_bzero(s, n) is the same as memset(s, 0, n), except that the
compiler is not allowed to delete a call to explicit_bzero even if the
memory pointed to by 's' is dead after the call. Right now, this effect
is achieved externally by having explicit_bzero be a function whose
semantics are unknown to the compiler, and internally, with a no-op
asm statement that clobbers memory. This does mean that small
explicit_bzero operations cannot be expanded inline as small memset
operations can, but on the other hand, small memset operations do get
deleted by the compiler. Hopefully full compiler support for
explicit_bzero will happen relatively soon.
There are two new tests: test-explicit_bzero.c verifies the
visible semantics in the same way as the existing test-bzero.c,
and tst-xbzero-opt.c verifies the not-being-optimized-out property.
The latter is conceptually based on a test written by Matthew Dempsky
for the OpenBSD regression suite.
The crypt() implementation has an immediate use for this new feature.
We avoid having to add a GLIBC_PRIVATE alias for explicit_bzero
by running all of libcrypt's calls through the fortified variant,
__explicit_bzero_chk, which is in the impl namespace anyway. Currently
I'm not aware of anything in libc proper that needs this, but the
glue is all in place if it does become necessary. The legacy DES
implementation wasn't bothering to clear its buffers, so I added that,
mostly for consistency's sake.

This patch implements support for the __STDC_WANT_LIB_EXT2__ feature
test macro from ISO/IEC TR 24731-2:2010, thereby implementing one
possible approach for supporting ISO C feature test macros.
Recall that, as described in
<https://sourceware.org/ml/libc-alpha/2016-05/msg00486.html>, these
macros work based on the definition when affected headers are
included, so cannot be handled once when the first system header is
included because that might not be one of the headers the particular
macro in question affects.
<https://sourceware.org/ml/libc-alpha/2016-05/msg00680.html> expresses
views on possible approaches for implementation and
<https://sourceware.org/ml/libc-alpha/2016-06/msg00039.html> follows
up on that.
This patch arranges things so that the relevant condition is
__GLIBC_USE (LIB_EXT2), following one of the suggestions given.
Headers using these macros include <bits/libc-header-start.h>, which
in turn includes <features.h>. Headers must define
__GLIBC_INTERNAL_STARTING_HEADER_IMPLEMENTATION before including
<bits/libc-header-start.h>, to discourage inclusion outside glibc as
requested. __USE_GNU conditions on affected functions are changed to
__GLIBC_USE (LIB_EXT2), while it's added as an additional alternative
on the conditions for functions already enabled for some POSIX
versions.
It would be possible to convert existing __USE_* conditionals to
__GLIBC_USE (with the relevant __GLIBC_USE_* being defined in
<features.h> where __USE_* are presently defined), and so make them
typo-proof (given -Wundef -Werror in glibc builds) because __GLIBC_USE
is used with #if not #ifdef / #if defined.
No attempt is made to enforce the rule about diagnosing different
definitions of __STDC_WANT_LIB_EXT2__ when affected headers are
included; such a diagnostic is incompatible with multiple-include
guards on the affected headers, unless compiler extensions are added
to support it.
As previously noted, glibc does not implement all features from TR
24731-2:2010: the functions aswprintf vaswprintf getwdelim getwline
are not in glibc, although they would be appropriate to add if someone
wished to do so. But I think it makes sense to support the feature
test macro if *any* of the controlled features are present in glibc.
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch).

This patch completes the headers cleanup consequent on removal of
_BSD_SOURCE and _SVID_SOURCE (apart from any subsequent deprecations):
* #endif conditionals that referred to BSD or SVID are updated.
* Redundant __USE_* tests in cases involving __USE_MISC are removed.
This includes cases such as __USE_MISC || __USE_ISOC99, where
__USE_MISC is redundant (because __USE_MISC is only ever defined in
the default / _DEFAULT_SOURCE / _GNU_SOURCE case, when __USE_ISOC99
is also defined; the same applies to the non-XSI-extended POSIX
versions), and cases involving __USE_GNU, where __USE_GNU is
redundant (because if __USE_GNU is defined, so are the other __USE_*
macros). There may well be other cases of __USE_FOO || __USE_BAR
tests that could be simplified because one macro implies the other;
this patch only addresses cases involving __USE_MISC.

This patch cleans up cases of __USE_MISC that are trivially redundant
after the recent substitution of __USE_MISC for __USE_BSD and
__USE_SVID: either in constructs such as "defined __USE_MISC ||
defined __USE_MISC", or else (in the bits/mman.h case) a conditional
on __USE_MISC nested inside another __USE_MISC conditional. (The
cleanups remaining after this patch are still quite large, but it
seems a reasonable piece to separate out.)

This patch cleans up following the obsoletion of _BSD_SOURCE and
_SVID_SOURCE by combining __USE_BSD and __USE_SVID into __USE_MISC.
The only non-mechanical part of this patch is the changes to
features.h; everything else is simple substitution of __USE_MISC for
the old macros. Thus, this patch leaves obviously redundant
conditionals such as "defined __USE_MISC || defined __USE_MISC", and
does not update #endif comments where they referred to BSD or SVID in
words instead of the literal macro name. This is intended to
facilitate patch review by separating the less mechanical changes from
these purely mechanical changes into a separate patch. (I do intend
to integrate all the changes from
<https://sourceware.org/ml/libc-alpha/2013-12/msg00226.html>, which I
believe includes all the trailing comment updates, in subsequent
patches.)

In the string/string.h and string/strings.h headers, we have a couple
of macros that "tell the caller that we provide correct C++
prototypes" according to the comment; they are used to determine
whether to wrap some prototypes in "extern "C++"" (and provide
multiple overloads of them, and some other magic) when __cplusplus is
defined.
The macros are set to check for sufficiently-recent GCC versions (4.4
and later), but this is not the right check for non-GCC compilers. In
particular, these macros should also be set when using Clang -- if
they are not set, then Clang will be unable to correctly diagnose a
number of subtle bugs that will be errors in GCC compilations.
As per discussion on earlier versions of this patch, rather than
restrict the fix to Clang per se, we assume that all C++ compilers that
claim to fully support C++98 are using a standard-conforming C++
standard library, which seems pretty reasonable. Clang has been
providing an appropriate value of __cplusplus since May 2012.

Not using the result of the GNU strerror_r() is always a mistake.
Moreover this would generate warning if XSI version was expected but GNU
version was used instead (because some random used header defined
_GNU_SOURCE which was Python.h in this case).

No more __const.

The header conformance testing code needed extending for XPG7. This
exposed a few bugs in the headers. There are more changes to come.
