Pedro Alvarez 0c20b7a455 Added support for S1AP modify bearer request support. This includes: 
- 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.

Andre Puschmann fab86382c1 mac,rrc: add interface to set SR config explicitly without touching any other MAC function 
when releasing PUCCH/SRS (see 5.3.13 in 36.331) we need to reset the SR config as well.
In our case, SR is handled by MAC so we need to (re-)configure MAC, not all of
MAC though, just SR.

Andre Puschmann 795db30338 pdcp: drop PDCP control PDUs 
this patch adds a check to drop all PDCP control PDUs
in order to prevent handling them as data PDUs.

This could happen when the size exceeded the arbitrary length check.

This should fix #1787
