Add ARMv8/AArch32 Crypto Extension implementation of SHA-1
* cipher/Makefile.am: Add 'sha1-armv8-aarch32-ce.S'.
* cipher/sha1-armv7-neon.S (_gcry_sha1_transform_armv7_neon): Add
missing size.
* cipher/sha1-armv8-aarch32-ce.S: New.
* cipher/sha1.c (USE_ARM_CE): New.
(sha1_init): Check features for HWF_ARM_SHA1.
[USE_ARM_CE] (_gcry_sha1_transform_armv8_ce): New.
(transform) [USE_ARM_CE]: Use ARMv8 CE implementation if HW supports
it.
* cipher/sha1.h (SHA1_CONTEXT): Add 'use_arm_ce'.
* configure.ac: Add 'sha1-armv8-aarch32-ce.lo'.
