Add (placeholder) CCM module
Add ccm_init/free()
Add ccm_encrypt_and_tag()
Add NIST CAVS 11.0 test vectors for AES-CCM

Since there are 2160 test vectors fro encryption, which is a lot,
only the first one (out of ten) for each length quadruple was kept.
Refactor to prepare for CCM decryption
Implement ccm_auth_decrypt()
Add test for length checks
Use tighter buffers in CCM test suite
Add CCM to benchmark
CCM source cosmetics/tune-ups

- source a bit shorter
- generated code slightly smaller
- preserving performance
CCM operations allow input == output
Add test vectors for Camellia-CCM
Add cipher_crypt()
Use cipher_crypt() in ssl_tls.c
Add cipher_auth_{en,de}crypt()
Use cipher_auth_{en,de}crypt() in ssl_tls.c
Add AES-CCM and CAMELLIA-CCM to the cipher layer
Register CCM ciphersuites (not implemented yet)
Small readability improvement
Implement CCM and CCM_8 ciphersuites
