Andre Puschmann e2146e90ad enb: remove usleep after sending RRC Connection Release to UE 
this cause a "dead-lock" with ZMQ because it made the stack
thread sleep for 50ms. With a sync-queue size of 1 (now the default
using ZMQ) the zmq-based radio to timeout. as a result
the rx/tx between UE and eNB stopped so the UE never reached
RRC Idle state.

* Added the appropriate code for handling and sending the
   re-establishment procedure messages to rrc_ue.c/.h.

   re-establishment complete
 * Refreshed K_eNB at the reception of re-establishment

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.

Andre Puschmann ed179fd311 timers: rename value() to time_elapsed()

Andre Puschmann 179fd394b2 enb: add SRB2+DRB1 to scheduler AFTER receiving Reconfig Complete 
this commit fixes and issue where, after receiving paging and the resulting
PRACH from the UE, the eNB would create DRB1 and already schedule DL traffic
on this bearer. However, since the UE has not received the reconfig message
yet, the DL traffic is dropped since DRB1 isn't set up yet.

the commit also does not reset the BSR state of the bearer inside MAC since
this caused to a stall of the received DL PDU. The value would initially be set to
a non-zero value (after receiving the DL PDU from EPC). But when the bearer
was (re-)introduced to MAC, it would reset the BSR to zero, and, since
MAC never polls RLC, the PDU wasn't sent down until the next PDU arrives
and sets the BSR to a non-zero value again.

Andre Puschmann fef6893ce4 make user activity handling independent of system time 
this commit removes the getsystime() call from the activity handling.
it uses a single timer per UE to handle its activity.

three different timer values exist. one for the Msg3 reception. This
is like before and is quite low to quickly remove fake UEs from the
RRC. The second is a generic value (set to 1s for now) that covers
the entire UE configuration phase where multiple messages are sent
back and forth until the UE is fully set up and the default
bearer runs. From there on, the UE inactivity timer is used which
may be much bigger than 1s.
