Pedro Alvarez 960c0e97cd Added handling of RRC re-establishment to srsENB. 
* Added the appropriate code for handling and sending the
   re-establishment procedure messages to rrc_ue.c/.h.
 * Triggered RRC reconfiguration after the reception of RRC
   re-establishment complete
 * Refreshed K_eNB at the reception of re-establishment
   request
 * Changed the mapping of TEIDs to RNTIs in the GTP-U layer,
   as the RNTI might change with reestablishment.

Andre Puschmann 2edecea33e fix SIB transmission for CA 
Avoid double buffering of SIBs in MAC as this would require one buffer for each CC.
Instead, use byte_buffer managed by RRC that contains packed SIBs to avoid
double memcpy for each SIB tx. Only use MAC provided buffer in error case.

Also avoid MAC calling RLC for each SIB and call RRC directly.

- introduce cell list to MAC
- adapt default enb.conf.example and rr.conf.example
