libosmo-gprs-rlcmac: check-in PDU definitions from osmo-pcu.git

This commit introduces a new library called 'libosmo-gprs-rlcmac',
which is going to be used by osmo-pcu and osmocom-bb for parsing
and generation of PDUs defined using CSN.1 (see 3GPP TS 24.007).

The actual RLC/MAC definitions are imported from osmo-pcu.git [1].
