	(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.
