	extracted from the serpent package.

	* twofish.c: Adapted to nettle. Made constant tables const.
	Deleted bytes_to_word and word_to_bytes; use LE_READ_UINT32 and
	LE_WRITE_UINT32 instead.
	(twofish_selftest): Deleted. Moved the tests to the external
	testsuite. 
	(twofish_set_key): Don't silently truncate too large keys. 

	* sha1.c (sha1_update): Use unsigned for length.

	* serpent.c (serpent_set_key): Read the key backwards. Fixed
	padding (but there are no test vectors for key_size not a multiple
	of 4).
	(serpent_encrypt): Read and write data in the strange order used
	by the reference implementation.
	(serpent_decrypt): Likewise.

	* macros.h (FOR_BLOCKS): New macro, taken from lsh.

	* blowfish.h (struct blowfish_ctx): Use a two-dimensional array
	for s.

	* blowfish.c (initial_ctx): Arrange constants into a struct, to
	simplify key setup.
	(F): Deleted all but one definitions of the F function/macro.
	Added a context argument, and use that to find the subkeys.
	(R): Added context argument, and use that to find the subkeys.
	(blowfish_set_key): Some simplification.

	(encrypt): Deleted code for non-standard number of rounds. Deleted
	a bunch of local variables. Using the context pointer for
	everything should consume less registers.
	(decrypt): Likewise.

	* Makefile.am (libnettle_a_SOURCES): Added twofish.

	* testsuite/blowfish-test.m4: Fixed test.

	* Added twofish implementation.

	* blowfish.h (struct blowfish_ctx): Use the correct size for the p
	array.

	* testsuite/blowfish-test.m4: Added one test, from GNUPG.

	* Created blowfish.c and blowfish.h (from GNUPG via LSH). Needs
	more work.

	* aes.h: Fixed copyright notice to not mention GNU MP. XXX: Review
	all nettle copyrights.

	* testsuite/Makefile.am (TS_PROGS): Added tests for twofish and
	blowfish.
