There is no prototype of _gcry_sha256_transform_intel_shaext() defined
in the header or libgcrypt-grub/cipher/sha256.c, and gcc may complain
the missing-prototypes error when compiling sha256-intel-shaext.c.
Declare the prototype in sha256-intel-shaext.c to avoid the error.

gpg_err_code_from_errno() requires libgcrypt_wrap/mem.c which is not in
Makefile.utilgcry.def. This commit replaces gpg_err_code_from_errno()
with GPG_ERR_* to avoid the build errors.

The hash_buffers() functions are disabled in GRUB by default but the
Argon2 implementation requires hash_buffers() for BLAKE2b-512.
This commit implements argon2_blake2b_512_hash_buffers() as the
replacement of _gcry_digest_spec_blake2b_512.hash_buffers().

Libgcrypt code assumes that on x64 all SSE registers are fair game.
While it's true that CPUs in question support it, we disable it in
our compilation options. Disable the offending optimization.
