Jacob Erlbeck 9659d59307 tbf: Keep the old MS object alive in extract_tlli
Currently when a second MS object has been created for an MS, because
the TLLI was not known yet, the will be detected in
gprs_rlcmac_tbf::extract_tlli and the two objects will be merged by
update_ms. But when the dl_tbf is moved from the old to the new
(second) MS object, the old MS object can get idle and be removed
before the object are merged. This can cause LLC frame loss when the
MS object is deleted immediately after getting idle (no timeout
configured).

This commit adds a guard to keep the MS object until extract_tlli has
been executed.

README

This is an implementation of Packet Control Unit (PCU) according to TS 04.60

The PCU is part of BSS, so it connects directly to SGSN.


== Current limitations ==

 * No PFC support
 * 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
