Fix resolver bind, getsockname namespace (bug 17733).
On Linux architectures using socketcall, the resolver ends up bringing
in strong symbols for bind and getsockname, which are not in
POSIX.1-1996. This causes linknamespace test failures:
FAIL: conform/POSIX/pthread.h/linknamespace
FAIL: conform/POSIX/sched.h/linknamespace
FAIL: conform/POSIX/time.h/linknamespace
These functions are defined as strong symbols with __bind and
__getsockname as weak aliases. This patch switches this to the other
way round by removing the NO_WEAK_ALIAS definitions and so letting the
default case in socket.S act; I see no reason for the existing
arrangements.
Tested for x86 (testsuite, and that disassembly of installed shared
libraries is unchanged by the patch).

Fix profil_counter namespace (bug 17725).
On ARM, where profil_counter is not static, it is brought in by
references to various standard functions, as noted in
<https://sourceware.org/ml/libc-alpha/2014-11/msg00890.html>, although
it is not a standard function itself. I don't know if this also
causes test failures on SPARC, although I see no reason for it not to
do so.
This patch fixes this namespace issue. profil_counter is renamed to
__profil_counter and made a weak alias on ARM and SPARC. Because of
the uses in profil.c / sprofil.c it seems simplest to make the rename
globally, including on the other architectures for which
profil_counter was static and so the change is of no substance. The
variant names profil_counter_* used in sprofil.c are also renamed to
start with __ so that undesired function names do not get exported in
static libc.
As I noted in bug 17726, profil_counter should probably be a compat
symbol on ARM and SPARC, so it wouldn't exist at all in static libc
even as a weak alias. Since defining a compat symbol still requires
an internal name as a target of an alias, this patch still seems
reasonable as an intermediate step towards that goal: it wouldn't be
possible for the function simply to be static profil_counter on ARM
and SPARC with profil_counter also being the exported compat symbol
name, so profil.c / sprofil.c would still need to be prepared to call
the function under another name (here, __profil_counter).
Tested for x86_64 (testsuite, and that stripped installed shared
libraries are unchanged by the patch) and ARM (ABI and linknamespace
tests - this patch reduces the number of linknamespace failures I see
on ARM from 227 to 5, the residue being math.h failures for fe*
functions and for j0l/j1n/jnl/y0l/y1l/ynl aliases).

intl: Merge with gettext version 0.19.3
This patch merges the latest release of gettext into the intl
subdirectory. The initial motivation was to include the plural.y
changes which enable building with bison 3.0, but the majority
of the other changes are merely cosmetic so it seemed like merging
the whole directory was simpler than trying to take it piecemeal.
The merge was done by copying across the latext gettext code and
adding in a few small glibc changes that have been added over the
years that seemed beneficial, as well as a couple of small build
fixes that should be merged back to gettext. I also reverted the
gettext commit:

Make absolute pathnames inside $LANGUAGE work.
As it caused localedata/tst-setlocale3 to fail and it wasn't clear
that glibc wanted that behaviour.
The merge has dropped many uses of __glibc_likely/unlikely. This is
intentional given that it eases merging. It seems to me that the cost
of continually rewriting these lines when merging and the risk of adding
bugs when doing so outweighs the benefits of using these macros when
code is shared with another project.

Use -Werror by default, add --disable-werror.
As discussed starting at
<https://sourceware.org/ml/libc-alpha/2014-11/msg00323.html>, this
patch makes the glibc build use -Werror by default to avoid
accidentally adding new warnings to the build. The configure option
--disable-werror can be used to disable this.
-Wno-error=undef is temporarily used because the build isn't clean
regarding -Wundef warnings. The idea is that once the remaining
-Wundef warnings have been cleaned up (in at least one configuration),
-Wno-error=undef will be removed.
I get a clean build and test on x86_64 (GCC 4.9 branch) with this
patch. The expectation is that this may well break the build for some
other configurations, and people seeing such breakage should make
appropriate fixes to fix or suppress the warnings for their
configurations. In some cases that may involve using pragmas as the
right fix (I think that will be right for the -Wno-inline issue for
MIPS I referred to in
<https://sourceware.org/ml/libc-alpha/2012-11/msg00798.html>, for
example), in some cases -Wno-error in sysdeps makefiles (__restore_rt
in MIPS sigaction, for example), in some cases substantive fixes for
the warnings.
Note that if, with a view to listing all the warnings then fixing them
all, you just look for "warning:" in output from building and testing
with --disable-werror, you'll see lots of warnings from the linker
about functions such as tmpnam. Those warnings can be ignored - only
compiler warnings are relevant to -Werror, not linker warnings.
