196 reducing cyclomatic complexity

[rjbrown2]

This is missing some DOxygen boilerplate, but I'll add that in after this has been reviewed.
If you guys could review function names, and the refactoring in general that would be helpful. There will be additional TM requests in the near future. This merge mainly deals with TC, and a couple of other minor refactors:

crypto_tc:

Crypto_TC_Apply_Security_Cam
Crypto_TC_Process_Security_Cam
sadb_routine_inmemory_template.c:

sadb_get_operational_sa_from_gvcid
crypto.c:

Crypto_Check_Anti_Replay
cryptography_interface_lib_gcrypt_template.c:

cryptography_aead_encrypt
cryptography_validate_authentication
cryptography_aead_decrypto.c
base64url.c:

base64urlDecode
standalone.c:

crypto_standalone_tm_process

Standby for fixes to the two failing build tests.

Do we have pre/post complexity numbers that we could capture here as well?

Looks good, just a few comments. Big changes to TC but we expected that

I have the original XML and its numbers/findings within CAP. I added an additional column for tracking the changes.
