Pedro Alvarez ca603810ce Adding Downlink data notification and paging functionality to the EPC. 
This entails:

  * Adding S1AP paging messaging to the MME.
  * Adding the Downlink Data Notification, Donlink Data Notification Acknoledgment, and Downlink Data Notification Failure Messages.
  * Adding the logic at the GTP-U to detect that Downlink Data notification needs to be sent.
  * Proper handling of the new GTP-C messages at the MME GTPC and SPGW GTPC classes
  * Add queuing mechanisms at the GTP-U while waiting for paging response. Queue is flushed when paging fails (timeout or other).
  * Make sure eNB's SCTP information is properly stored.
  * Make sure UE's GUTI information is properly stored.

Andre Puschmann 94481c1963 removed warning in RLC if LCID isn't valid for all methods called by BSR procedure

Andre Puschmann 99e0bda779 let valgrind fail when test app returns 0 but valgrind still found an error 
this allows to trace uninitialized variables etc with our default
memcheck runs because now valgrind will fail such a test, even though
the test executable returned zero on exit

Andre Puschmann c8f8c16d50
make EIA and EEA algorithms configurable (#323) 
this patch allows to configure the EIA and EEA algorithms
the UE uses and announces during attach. They can
be specified as a comma-separated list.

The patch also removes a dedicated NAS config class and uses
the default nas_args_t type for this. There was a full
duplication of members before.

The patch also converts nas_args_t and usim_args_t into a class
with a default constructor that initialize all booleans.
