gettimeofday is currently guarded with __MISC_VISIBLE || __XSI_VISIBLE.
However, gettimeofday should be always visible, as in GLibc.

The proper location for these functions has always been <stdio.h>, however
XPG4 and SUSv2 did mandate a duplicate declaration in <unistd.h>. cuserid
was dropped in SUSv3 (it was marked legacy since XPG4) and the ctermid
declaration in <unistd.h> was made optional and obsolete in SUSv4.

Sure, I've attached the patch.

Add a simple rawmemchr implementation. Use strlen for rawmemchr(s, '\0') as it is the
fastest way to search for '\0', and use memchr with an infinite size for other cases.
This is 3x faster for large sizes.
ChangeLog:
2016-04-22 Wilco Dijkstra <wdijkstr@arm.com>
* newlib/libc/machine/aarch64/Makefile.in: Add rawmemchr.S and
rawmemchr-stub.c.
* newlib/libc/machine/aarch64/Makefile.am: Likewise.
* newlib/libc/machine/aarch64/rawmemchr.S (rawmemchr): Add rawmemchr.
* newlib/libc/machine/aarch64/rawmemchr-stub.c (rawmemchr): Likewise.
The following testcase:
$ cat > test.c <<EOF
#include <sys/select.h>
#include <sys/time.h>
EOF
$ gcc -c test.c
emits the following error:
/usr/include/sys/reent.h:276:3: error: expected specifier-qualifier-list befor
e ‘_fpos64_t’
_fpos64_t _EXFNPTR(_seek64, (struct _reent *, _PTR, _fpos64_t, int));
^
The reason is that the load order from sys/select.h includes sys/_types.h
before sys/config.h has been included from anywhere else. sys/_types.h
defines _fpos64_t only if __LARGE64_FILES is defined, but it never is in
this scenario. So sys/_types.h has to make sure to get the configuration
info by itself.

* libc/machine/arm/strlen-stub.c: Check capabilities of architecture
to decide which Thumb implementation to use and fall back to C
implementation for architecture not supporting Thumb mode.
* libc/machine/arm/strlen.S: Likewise.
Add _Thread_queue_Queue::_owner which will be used for the upcomming
priority inheritance implementation and an O(m) independence-preserving
protocol (OMIP) implementation.

Move _Thread_queue_Queue::_Lock to begin of the structure. On RTEMS,
the presence of a lock component in the thread queue structures actually
depends on the build-time RTEMS_SMP configuration option. A move of
this part to the begin of the structure allows an implementation re-use
for the other parts.

If the passed t pointer is not a null pointer, always assign the return
value to the object it points to, regardless of whether the return value
is an error.
This is what the GNU C Library does, and this is also the expected
behavior according to the latest draft of the C programming language
standard (C11 ISO/IEC 9899:201x WG14 N1570, dated 2011-04-12):

Resurrect <machine/_user_types.h> for use in <sys/types.h>. Newlib
targets may provide an own version of <machine/types.h> in their machine
directory to add custom user types for <sys/types.h>. Check the
_SYS_TYPES_H header guard to prevent a direct include of
<machine/types.h>, since the <machine/types.h> file is a Newlib
speciality.

The dummy crt0.c provided by the RTEMS target provides stubs of
symbols which would normally be provided by RTEMS. This patch adds
stubs for posix_memalign() as well as the synchronization methods
prototyped in <sys/lock.h>.
Various FreeBSD source and header files need a typedef __size_t via
<sys/_types.h>. Unfortunately the GCC provided <stddef.h> uses
#if (defined (__FreeBSD__) && (__FreeBSD__ >= 5)) \
|| defined(__DragonFly__) \
|| defined(__FreeBSD_kernel__)
/* __size_t is a typedef on FreeBSD 5, must not trash it. */
#elif defined (__VMS__)
/* __size_t is also a typedef on VMS. */
#else
#define __size_t
#endif
and therefore defines __size_t on Newlib targets which would trash a
__size_t typedef. Include <stddef.h> before <sys/_types.h> in
<sys/types.h> and undefine __size_t in <sys/_types.h> as a workaround.
