Paul Elliott e0a12bd852 Refactor aead setup functions into single function
Move common encrypt / decrypt code into common function, and roll in
previously refactored setup checks function, as this is now the only
place it is called.

Paul Elliott 66696b5591 Improve nonce length checks
Add the missing nonce length checks (this function is being used by
oneshot functions as well as multipart, and thus all cipher suites are
being used) and cover the case where a NULL buffer gets passed in.
Extended the set nonce test to cover this.

Paul Elliott ed08cf884a Add safety check to chachapoly finish
Previous code checked that the buffer was big enough for the tag size
for the given algorithm, however chachapoly finish expects a 16 byte
buffer passed in, no matter what. If we start supporting smaller
chachapoly tags in the future, this could potentially end up in buffer
overflow, so add a safety check.

Paul Elliott ebf91638b5 Move set nonce / set length tests to positive test
Previous test in state test was not actually making sure that the
operatioon could be completed using set lengths / set nonce in either
order, thus changed the 'normal' encrypt / decrypt tests to run in
alternating order.

Paul Elliott 97fd1bad83 Convert over to using a single internal test func
Make all encrypt/decrypt tests use the same function. Cleanup arguments
that were poorly named and document internal function. Removed one test
as I didn't want to write another test purely for it, when its already
tested in one shot.

Paul Elliott 315628d91a Remove internal aead_verify endpoint
The internal verify endpoint was only calling the finish endpoint to get
a tag to compare against the tag passed in. Moved this logic to the
driver wrapper (still allowing a driver to call verify if required) and
removed the internal implementation endpoint.
