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.

improve function that map ro to ssb in the UE: make dynamic smaller memory allocation than array[max][max][.... Saves about 100MB of memory and avoid real time glitch of milli seconds of memset(110MB)

Some places (e.g., 4G eNB/UE nfapi mode) use numbers for the FAPI mode,
directly mapping to an enum. Aerial being in the middle messes up these
numbers. Put it at the end to limit possible problems.
