- Generalize CryptoInterface.

Browse Source 
- Add more HMAC and hash functions to CryptoInterface.

- Add MeshCryptoInterface as a holder of mesh specific crypto functionality.

- Rename broadcastMetadataDelimiter to metadataDelimiter in FloodingMesh since it is not just used for broadcasts, and to save some typing.
