Title: Add support for encryption and decryption calls

This small pull request adds support for calling encryption and decryption functions in the netstack, if such functions are defined. Encryption and decryption shouldn't be done below the RDC layer, as it would incur delays that could disrupt the behavior of timing-sensitive RDC layers. It can't be done at the MAC or network layers either, as it is the RDC layer that gives radio packets their link-layer frames.
