Use the correct function in order to close open RFsim connections,
instead of a simple close(). If this is not done correctly, it might
happen that the softmodem closes, but an L1 thread might still read
samples (bug in higher layers). Then, RFsim tries to read a socket
(because it has an open connection), but the actual connection had been
close()d. This commit fixes this behavior.

add RA stat trace by enum name instead of integer printing

fix minor a few minor typos

The F1AP message encoders and decoders should do only that, encoding and
decoding messages. For the actual logic handling, including set up and
teardown of bearers, we should use the handlers.

In this commit, delete GTP tunnel handling from encoders/decoders. For
the CU, this happens already in the CU-UP/E1 handlers in
cucp_cuup_handler.c.  For the DU, add it in the handlers in
mac_rrc_dl_handler.c.

For the moment absoluteFrequencySSB is hardcoded. Fixed in a following commit.

From the spec, it does not seem to be mandated to check that the random
identity needs to be unique within a cell. Also, from experience we see
that this only happens when the same UE "comes back"; so since one UE
can only have one connection, the other RRC UE contexts (with the same
identity) should be removed at some point, anyway, leaving only one with
the same identity.

MIT is compatible with OAI public v1.1, so it can be added.

Add a sequence container in OAI. Includes for_each algorithm, doxygen
odcumentation, and test using ctest.
