Add ARM/NEON implementation of Poly1305
* cipher/Makefile.am: Add 'poly1305-armv7-neon.S'.
* cipher/poly1305-armv7-neon.S: New.
* cipher/poly1305-internal.h (POLY1305_USE_NEON)
(POLY1305_NEON_BLOCKSIZE, POLY1305_NEON_STATESIZE)
(POLY1305_NEON_ALIGNMENT): New.
* cipher/poly1305.c [POLY1305_USE_NEON]
(_gcry_poly1305_armv7_neon_init_ext)
(_gcry_poly1305_armv7_neon_finish_ext)
(_gcry_poly1305_armv7_neon_blocks, poly1305_armv7_neon_ops): New.
(_gcry_poly1305_init) [POLY1305_USE_NEON]: Select NEON implementation
if HWF_ARM_NEON set.
* configure.ac [neonsupport=yes]: Add 'poly1305-armv7-neon.lo'.
