Add bulk processing for hash transform functions

* cipher/hash-common.c (_gcry_md_block_write): Preload 'hd->blocksize'
to stack, pass number of blocks to 'hd->bwrite'.
* cipher/hash-common.c (_gcry_md_block_write_t): Add 'nblks'.
* cipher/gostr3411-94.c: Rename 'transform' function to
'transform_blk', add new 'transform' function with 'nblks' as
additional input.
* cipher/md4.c: Ditto.
* cipher/md5.c: Ditto.
* cipher/md4.c: Ditto.
* cipher/rmd160.c: Ditto.
* cipher/sha1.c: Ditto.
* cipher/sha256.c: Ditto.
* cipher/sha512.c: Ditto.
* cipher/stribog.c: Ditto.
* cipher/tiger.c: Ditto.
* cipher/whirlpool.c: Ditto.
