commit 1bcfa9aacfef875f21aeb3d6b5bd393b069e4183
Author: Minh-Quang Nguyen <minh-quang.nguyen at nutaq.com>

    PCU: Fix TA adjustment
    
    Promblem:
     TA provided from L1 PH-DATA-IND is a relative amount of TA adjustment to actual TA
     being used for given TBF. The current TA update algorithm in PCU simply applies the relative
     amount of TA to given TBF but does not take into account of current TA.
     As a result, the PCU will request wrong TA jump for given TBF if the MS is moving away from
     BTS more than 2 km.
    
     Related issue: http://osmocom.org/issues/2611
    
    Fixes:
    - The PCU needs increase or decrease current TA of given TBF on receiving of relative
      amount of TA adjustment provided by PH-DATA-IND from L1
    - The PCU needs to set absolute TA of given TBF on receiving absolute TA provided by
      PH-RA-IND from L1.
