Changes:
v7:
- fix test to handle app parameter correctly.
v6:
- checkpatch related fix.
v5:
- Release notes.
v4:
- AES GMAC callback fixes.
v3:
- patches 5,6 and 7 in v2 are rebased and submitted here.
v2:
- minor fixes in v1
- addition of digest encoding for fips validation
- addition of message randomization for fips conformance tests.
