gcm_key *.
(gcm_hash): Replaced context argument by a struct gcm_key * and a
pointer to the hashing state block.
(gcm_auth): Added struct gcm_key * argument.
(gcm_encrypt): Likewise.
(gcm_decrypt): Likewise.
(gcm_digest): Likewise.

* gcm.h (struct gcm_key): Moved the key-dependent and
message-independent state to its own struct.
(struct gcm_ctx): ... and removed it here.
(GCM_CTX): New macro.
(GCM_SET_KEY): Likewise.
(GCM_AUTH): Likewise.
(GCM_ENCRYPT): Likewise.
(GCM_DECRYPT): Likewise.

named h, with array size depending on GCM_TABLE_BITS.

Rev: nettle/gcm.h:1.6

(gcm_gf_mul): Compile bitwise version only when GCM_TABLE_BITS ==
0. Simplified interface with just two arguments pointing to
complete blocks.
(gcm_gf_shift_4, gcm_gf_shift_8): Renamed table-based functions, from...
(gcm_gf_shift_chunk): ... old name.
(gcm_gf_mul): Renamed both table-based versions and made the
argument types compatible with the bitwise gcm_gf_mul.
(gcm_gf_mul_chunk): ... the old name.
(gcm_set_key): Initialize the table using adds and shifts only.
When GCM_TABLE_BITS > 0, this eliminates the only use of the
bitwise multiplication.
(gcm_hash): Simplified, now that we have the same interface for
gcm_gf_mul, regardless of table size.

(gcm_gf_shift_chunk): Fixed bugs for the big endian 64-bit case,
e.g., sparc64. For both 4-bit and 8-bit tables.

(gcm_gf_add): New function, a special case of memxor. Use it for
all memxor calls with word-aligned 16 byte blocks. Improves
performance to 152 cycles/byte with no tables, 28 cycles per byte
with 4-bit tables and 10.5 cycles per byte with 8-bit tables.

* gcm.c (gcm_gf_shift): Renamed. Tweaked little-endian masks.
(gcm_rightshift): ... old name.
(gcm_gf_mul): New argument for the output. Added length argument
for one of the inputs (implicitly padding with zeros).
(shift_table): New table (in 4-bit and 8-bit versions), generated
by gcmdata.
(gcm_gf_shift_chunk): New function shifting 4 bits at
a time.
(gcm_gf_mul_chunk): New function processing 4 bits at a time.
(gcm_set_key): Generation of 4-bit key table.
