This moves the implementation closer to the current IEEE 802.11 standard
since B15 of Frame Control field was renamed to +HTC to match it newer
uses.

By analysing objdump output some read only structures were found in
.data section. To help compiler further optimize code declare these
as const.

IEEE Std 802.11ad-2012 includes two test vectors for GCMP. Verify both
of those and also verify that the results match the values in the
standard instead of just verifying that decrypted frame matches
original.

This adds 192-bit and 256-bit key support to the internal AES
implementation and extends the AES-GCM functions to accept key length to
enable longer AES key use.

This is a generic AES GCM and GMAC implementation that can be used for
other purposes than just implementing GCMP, so it fits better in a
separate file in src/crypto.

There is no need to allocate a temporary buffer and build GHASH input
data into it. Instead, ghash() is trivial to split into update part that
can be called separately for each segment.

GCMP encodes length of AAD differently, so remove the unnecessary
code that got copied from the CCMP implementation.
