16396c41de Add _STRING_INLINE_unaligned and string_private.h
As discussed in

https://sourceware.org/ml/libc-alpha/2015-10/msg00403.html

the setting of _STRING_ARCH_unaligned currently controls the external
GLIBC ABI as well as selecting the use of unaligned accesses withing
GLIBC.

Since _STRING_ARCH_unaligned was recently changed for AArch64, this
would potentially break the ABI in GLIBC 2.23, so split the uses and add
_STRING_INLINE_unaligned to select the string ABI. This setting must be
fixed for each target, while _STRING_ARCH_unaligned may be changed from
release to release.  _STRING_ARCH_unaligned is used unconditionally in
glibc.  But <bits/string.h>, which defines _STRING_ARCH_unaligned, isn't
included with -Os.  Since _STRING_ARCH_unaligned is internal to glibc and
may change between glibc releases, it should be made private to glibc.
_STRING_ARCH_unaligned should defined in the new string_private.h heade
file which is included unconditionally from internal <string.h> for glibc
build.
