	* nettle.texinfo (Cipher functions): Updated AES documentation,
	for aes_set_encrypt_key and aes_set_decrypt_key.

	* cbc.h (nettle_crypt_func): Moved typedef here.	
	* cbc.c (cbc_encrypt, cbc_decrypt_internal, cbc_decrypt): Use it

	compatibility with nettle_crypt_func.

	nettle_des_set_key for referring to Nettle's function.

	* des.h (des_set_key): Name mangling, linker symbols should use a
	"nettle_" prefix, and this one collided with openssl. Perhaps all
	symbols should be mangled in a similar way, but that's for later. 

	* configure.ac (LDFLAGS): --with-lib-path should add to LDFLAGS,
