Cipher_Mode API improvements
The Cipher_Mode::update API is more general than needed to just
support ciphers (this is due to it previously being an API of
Transform which before 8b85b780515 was Cipher_Mode's base class)
Define a less general interface `process` which either processes the
blocks in-place, producing exactly as much output as there was input,
or (SIV/CCM case) saves the entire message for processing in `finish`.
These two uses cover all current or anticipated cipher modes.
Leaves `update` for compatability with existing callers; all that is
needed is an inline function forwarding to `process`.
Removes the return type from `start` - in all cipher implementations,
this always returned an empty vector.
Adds BOTAN_ARG_CHECK macro; right now BOTAN_ASSERT is being used
for argument checking in some places, which is not right at all.
