cast5: add ARMv6 assembly implementation
* cipher/Makefile.am: Add 'cast5-armv6.S'.
* cipher/cast5-armv6.S: New file.
* cipher/cast5.c (USE_ARMV6_ASM): New macro.
(CAST5_context) [USE_ARMV6_ASM]: New members 'Kr_arm_enc' and
'Kr_arm_dec'.
[USE_ARMV6_ASM] (_gcry_cast5_armv6_encrypt_block)
(_gcry_cast5_armv6_decrypt_block, _gcry_cast5_armv6_ctr_enc)
(_gcry_cast5_armv6_cbc_dec, _gcry_cast5_armv6_cfb_dec): New prototypes.
[USE_ARMV6_ASM] (do_encrypt_block, do_decrypt_block, encrypt_block)
(decrypt_block): New functions.
(_gcry_cast5_ctr_enc) [USE_ARMV6_ASM]: Use ARMv6 assembly function.
(_gcry_cast5_cbc_dec) [USE_ARMV6_ASM]: Use ARMv6 assembly function.
(_gcry_cast5_cfb_dec) [USE_ARMV6_ASM]: Use ARMv6 assembly function.
(do_cast_setkey) [USE_ARMV6_ASM]: Initialize 'Kr_arm_enc' and
'Kr_arm_dec'.
* configure.ac (cast5) [arm]: Add 'cast5-armv6.lo'.

Provides non-parallel implementations for small speed-up and 2-way parallel
implementations that gets accelerated on multi-issue CPUs (hand-tuned for
in-order dual-issue Cortex-A8). Unaligned access handling is done in assembly.
For now, only enable this on little-endian systems as big-endian correctness
have not been tested yet.
Old vs new (Cortex-A8, Debian Wheezy/armhf):
ECB/Stream CBC CFB OFB CTR
