Max d572054ca7 Properly set TA_VALID bit 
Check Timing Advance validity and set corresponding bit for Immediate
Assignment message. Previously !polling was errorneously used (polling
bit has nothing to do with TA validity according to 3GPP TS 44.018 Table
10.5.2.16.1) which lead to TA being always valid as polling is always 0
in other parts of the code.

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
 * 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
