Add ARM/NEON implementation for SHA-1
* cipher/Makefile.am: Add 'sha1-armv7-neon.S'.
* cipher/sha1-armv7-neon.S: New.
* cipher/sha1.c (USE_NEON): New.
(SHA1_CONTEXT, sha1_init) [USE_NEON]: Add and initialize 'use_neon'.
[USE_NEON] (_gcry_sha1_transform_armv7_neon): New.
(transform) [USE_NEON]: Use ARM/NEON assembly if enabled.
* configure.ac: Add 'sha1-armv7-neon.lo'.
