	* gcm.c (gcm_gf_mul_chunk): Special case first and last iteration.
	(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.

	Introduced 8-bit tables. If enabled, gives gmac performance of 19

	cycles per byte (still on intel x86_64).
	* gcm.c (gcm_gf_shift_chunk): New implementation for 8-bit tables.
	(gcm_gf_mul_chunk): Likewise.
	(gcm_set_key): Generate 8-bit tables.

	* Makefile.in (TARGETS): Added gcmdata.

	Introduced 4-bit tables. Gives gmac performance of 45 cycles per
	byte (still on intel x86_64).
	* 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.
	(gcm_hash): Use tables, when available.

	* gcmdata.c (main): New file.

	* gcm.c (gcm_rightshift): Moved the reduction of the shifted out
	bit here.
	(gcm_gf_mul): Updated for gcm_rightshift change. Improves gmac
	performance to 181 cycles/byte.

	* gcm.c (gcm_gf_mul): Rewrote. Still uses the bitwise algorithm from the
	specification, but with separate byte and bit loops. Improves gmac
	performance a bit further, to 227 cycles/byte.

	* gcm.c (gcm_rightshift): Complete rewrite, to use word rather
	than byte operations. Improves gmac performance from 830 cycles /
	byte to (still poor) 268 cycles per byte on intel x86_64.

	Reapplied optimizations (150% speedup on x86_32) and other fixes,
	relicensing them as LGPL.
	* blowfish.c (do_encrypt): Renamed, to...
	(encrypt): ...new name.
	(F): Added context argument. Shift input explicitly, instead of
	reading individual bytes via memory.
	(R): Added context argument.
	(encrypt): Deleted a bunch of local variables. Using the context
	pointer for everything should consume less registers.
	(decrypt): Likewise.
	(initial_ctx): Arrange constants into a struct, to simplify key
	setup.
	(blowfish_set_key): Some simplification.
