enb,rrc: delay UE release after RLC maxRetx
...
this fixes the eNB behaviour when RLC signals maxRetx reached.
By directly releasing the UE, we ignore the fact that the UE
could still have the reestablishment counters running, so
could attempt a reestablishment, which would result in a reject
because we would have destroyed the UE context too early.
this patch delays the removal of the UE to wait at least
until the reestablishment timers are expired.

- Handle received E-RAB S1AP at s1ap.cc.
- Added methods to rrc.cc, rrc_ue.cc and rrc_bearer_cfg.cc to handle erab modify request.
- Made RLC add_bearer() function capable of re-creating the RLC entity.
- Send RRC reconfiguration to the UE and reply to the EPC with S1AP
modify bearer response.
This commit also adds support to srsEPC to send S1AP modify bearer request for
testing purposes.
