Otherwise initialize __global_locale.ctype_ptr and __C_locale.ctype_ptr

__C_locale is const. Thus, overwriting the lconv values in __localeconv_l
will try to write to a R/O region. Given the lconv values in __C_locale
are initialized, there's no reason to write them in __localeconv_l at all.
Just return &__C_locale.lconv.

This reverts commit 4de8596. It worked around a problem which was
actually introduced by patch 10a30e7 a few weeks ago. Rather than
adding special code to the newlib version of __getreent, the followup
patch reinstantiates the original, Cygwin-only implementation of
__getreent.

So far the lib function __getreent always returned _impure_ptr. On Cygwin
this is only correct after _impure_ptr got initialized. The inline
function in include/cygwin/config.h always returns the right _reent ptr,
though.
After introducing per-thread locales, the __getreent function is called
prior to initialization of _impure_ptr (from dll_crt0_0) to access the
locale pointer, which leads to a crash.
Fix the __getreent lib function for Cygwin to return the correct _reent
pointer all the time. Rename inline function to __inline_getreent
and introduce a macro __getreent calling the inline function. Change
the lib function __getreent to call __inline_getreent on Cygwin.

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.
