The tcs (Tetra Crypto State) struct now maintains information relevant for decryption, such as the current network, colour code, hyperframe, etcetera.
Also, the upper mac now calls a stub decryption function when receiving an encrypted resource.

The upper mac now maintains a defragmentation buffer for each timeslot. Resources with length -1 (fragmentation start) are added to the buf for that slot, further mac/frag frames are appended. When a mac/end is encountered, the reconstructed l2 message is passed to rx_tm_sdu. The tetra_llc_pdu struct now uses a uint32_t for tl_sdu_len in order to account for the possibly longer sdus. Fill bits processing was required in order to reliably determine the end of a MAC PDU.
