Add (internal only) define to config.h which allows the temporary
implementation of CCM to work, by removing the buffer zeroization on tag
fail when decrypting. This will obviously be removed when multipart CCM
is properaly implemented

Remove spurious "not supported" returns, and fix same issue that was
encountered with internal implementations - operation needs to be
marked as a type even if the initial call fails, otherwise cleanup won't
get done.

All tests should have an abort call in case of test failure to make sure
everything is cleaned up. Also removed unused define.

Although this deviates from the standard "auto-generated" code, the
M-AEAD setup functions set the key and thus allocate memory. If the
failure occurs after this (invalid tag size for example) then not having
the id set to the internal drivers means that abort does not get called,
and this causes the allocated data to leak.

Some tests cause a zero length input or output, which can mean the
allocated test output buffers can be zero length. Protect against
calling memcpy blindly in these situations.

Move CCM to update all data at update step, as final step can only
output at most a block length, so outputting all data at this step
significantly breaks the tests. Had to add unpleasant workaround for the
validate stage, but this is the only way I can do things without
breaking CCM Alt implementations.

Fix memory leak due to aead_abort() using incorrect enums to identify
algorithm used. Fix incorrect return on failure to check tag on
aead_verify()

For the time being CCM and GCM are not entirely implemented correctly
due to issues with their underlying implentations, which would be
difficult to fix in 2.x, and thus require all the AD and data to be
passed in in one go.

Multipart AEAD operation struct has to be public as it's allocated by
the caller, so to save duplication of code, switch oneshot AEAD over to
using the multipart operation struct.

The changed logic is to try a sign-message driver (opaque or transparent);
if there isn't one, fallback to builtin sofware and do the hashing,
then try a sign-hash driver. This will enable to the opaque driver
to fallback to software.
