The header table and related code is currently unused - it was
included and used for canned mode, but canned mode has been removed,
so this code can be safely removed as well.
This indirectly fixes a bug reported by Dan Carpenter.

Define an in-kernel API for adding and removing compression modes,
which can be used by kernel modules or other kernel code that
implements IAA compression modes.
Also add a separate file, iaa_crypto_comp_fixed.c, containing huffman
tables generated for the IAA 'fixed' compression mode. Future
compression modes can be added in a similar fashion.
One or more crypto compression algorithms will be created for each
compression mode, each of which can be selected as the compression
algorithm to be used by a particular facility.
