- 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.
