- Replace uses of MD5 implementation in base with boringssl.
- Replace uses of internal MD4 implementation with boringssl.
- Use DES directly from boringssl and remove mozilla DES code.
- The existing DES code was partially using boringssl already.
- The existing DES code was setting parity itself. Now uses
boringssl's DES_set_odd_parity
- Re-implemented the mapping of a 128 bit NTLM hash 
onto three DES keys in Create3DesKeysFromNtlmHash
