0516e24d18 conformtest: Fix XPG standard naming. 
The conform/ tests test -D_XOPEN_SOURCE under the name "XPG3", and
-D_XOPEN_SOURCE -D_XOPEN_SOURCE_EXTENDED under the name "XPG4".

That naming is misleading.  _XOPEN_SOURCE_EXTENDED actually means
XPG4.2, including UX-shaded interfaces.  _XOPEN_SOURCE actually means
XPG4, or XPG4.2 without UX-shaded interfaces.  (Prior XPG versions
also used _XOPEN_SOURCE, but without any versioning of the values of
the macro, so XPG4.2 without UX-shaded interfaces is the only sensible
set of interfaces for glibc to expose given _XOPEN_SOURCE=1 without
_XOPEN_SOURCE_EXTENDED defined.)

This patch fixes the naming in the conform/ tests, so that what is now
called XPG4 is changed to XPG42, and what is now called XPG3 is
changed to XPG4.

Tested for x86_64 (and verified the complete set of expectations is
unchanged by the patch beyond the intended renaming).

caf2d83659 Use -std=c11 for C11 conform/ tests. 
Now that GCC 4.7 or later is required to build glibc, this patch makes
the conformance tests use -std=c11 for C11 tests instead of -std=c1x
-D_ISOC11_SOURCE.

Tested for x86_64 and x86 (conform/ tests).

	* conform/GlibcConform.pm ($CFLAGS{"ISO11"}): Use -std=c11 instead
	of -std=c1x -D_ISOC11_SOURCE.

f58573781c conformtest: use proper _POSIX_C_SOURCE value for POSIX. 
The conform/ tests were using -D_POSIX_C_SOURCE=199912 to test "POSIX"
(1995/6).  This patch changes them to use 199506L, the proper value
from the relevant edition of POSIX.  (This doesn't make any difference
to features.h, but is the logically correct value to use.)  Tested for
x86_64.

	* conform/GlibcConform.pm ($CFLAGS{"POSIX"}): Use
	-D_POSIX_C_SOURCE=199506L.

24f4f8253f Add tests for namespace for static linking. 
One thing we currently try to ensure manually is that glibc is
namespace-clean for static linking; that is, if you only use features
from a particular standard (including the set of features exposed by
headers given feature test macros such as _DEFAULT_SOURCE that don't
correspond to any written standard), the library objects brought in by
the static linker will not define or use (strong) names that are
reserved to the user in that standard.

This patch implements automatic tests for this, using the same set of
standards as for the header conformance tests (it would, however, be
easy to add more standards for this testing, without them needing to
have the definitions of expected header contents for the header
tests).  The tests are based on the functions declared in each header,
as extracted using GCC's -aux-info option.  The following comment from
linknamespace.pl explains the caveats around this approach:

Here's an example of the output for ISO (C90) assert.h, from before my

Of the 161 XFAILs, seven are the inevitable varargs.h and ndbm.h
failures; I think the remaining 154 mostly represent genuine bugs in
glibc that should mostly be straightforward to fix (probably rather
fewer than 154 bugs - issues generally affect multiple headers, for
multiple standards).  (When fixing, of course you need to file a bug
in Bugzilla, and check for the possibility that the header
conditionals are what's incorrect - that the first listed symbol
shouldn't have been declared, or that the symbol finally brought in
should have been declared.)
