Jacob Erlbeck 1ff70c26e3 sched: Do PACCH assignments for the same direction last 
Currently the selection of a pending control message is done round
robin. It can possibly happen, that a DL assigment is sent on a DL
TBF while an UL assignment is pending. The MS will replace the old
DL TBF in that case, so that it can no longer be used for the PACCH
so that the UL assignment is lost.

Give assigment requests for the same direction a lower priority.

 * No fixed allocation support
 * No extended dynamic allocation support
 * No unacknowledged mode operation
 * No PCCCH/PBCCH support
 * Only single slot assignment on uplink direction
 * No half-duplex class support (only semi-duplex)
 * No handover support
 * No measurement support
 * No TA loop
 * No power loop
 * No CS loop
 * No EGPRS
