as well as the file_logger object are in the common header in order
to allow the signal handler to flush the file if the alarm goes off.

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 33a410bda4 fix parsing of DL/UL earfcn in cell config 
using a single earfcn or dl_freq value that gets set by default

Andre Puschmann 9e113f8b27 pdcp: allow to configure security for rx/tx seperately 
previously PDCP security (integrity and ciphering) could only
be enabled for both Rx and Tx at the same time.

this, however, caused an issue during the conformance testing in which,
in TC_8_2_1_1() for example, the eNB sends a SecModeCommand and a
RRC Reconfiguration in the same MAC TB. In this case, the eNB
needs to be able to enable DL security right after sending the SecModeCmd
in order to send the RRCReconfig encrypted. However, enabling UL security needs
to be postponed until after the SecModeComplete is received.

This patch allows to enable PDCP security for rx/tx independently if
that is needed. The default way is like before, enabling it for tx/rx at
the same time.

Pau Espin Pedrol 4949df257e Proper shutdown on SIGHUP 
If a process exits and has a controlling terminal, everything under
it gets a SIGHUP by the kernel. That's the case for instance when
running a srsUE over ssh with some specific parameters. As a result,
when the ssh client is killed, SIGHUP is sent to srsUE, which will be
killed immediatelly without proper release, which means in turn that log
buffers are not flushed.
Let's do proper shutdown when SIGHUP is received so that everyone can
get log files.

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.

the 6 PRB eNB requires a different PRACH offset than the default

to use a separate SIB config with just a single different value,
the patch patches the value to the only right configuration, if it's wrong.
It continues operation but still issues a warning so the user
can change it in the config.

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.
