For the reestablishment, the SRB2 in the RRC reconfiguration
following the reestablishment needs to include ReestablishPDCP true.
We were not sending that. In this commit, I add a parameter to
add that parameter on demand. There might be a better solution.

Update 'Active' flag for SRB 2 when setting it up and avoind to add it multiple times in rlc_BearerToAddModList

Previously, in f1ap_decoder.c, we asserted if we did not know a message.
Apart form decoding, we did not do anything in that file.

Additionally, in f1ap_handlers.c, we were also checking for an unknown
message, and printing a warning if a handler is not known.

This commit moves the F1AP message decoding to f1ap_handlers.c, and
deletes f1ap_decoder.c. In summary, we don't assert on an unknown
message, and compile less files. The rest is unchanged.

We need to test security and integrity protection in the CI.

This commit activates ciphering+integrity protection for SRBs
and DRBs using nea2/nia2 for the amarisoft-ue + aw2s CI pipeline.

To allow users to install asn1c quickly in install, make this directory
to allow standalone execution of install_asn1c_from_source.

The instructions are now:
sudo ls  # open sudo session, required by install_asn1c_from_source
. oaienv # read of default variables
. cmake_targets/tools/build_helper # read in functions
install_asn1c_from_source # install

CMake now takes the option ASN1C_EXEC to select an asn1c to use for
compilation. For instance, run with
cmake .. -GNinja -DASN1C_EXEC=/opt/asn1c/bin/asn1c
or
./build_oai --cmake-opt -DASN1C_EXEC=/opt/asn1c/bin/asn1c
to select the alternative asn1c. For instance, this is important for the
CI to allow to build multiple versions of OAI in parallel that might use
different commits of OAI.

Further, this patch introduces functionality to check for the support of
asn1c options that we require, and alerts the user if they are missing,
alongside a message of how to resolve the problem.

We don't work much on asn1c. The version we use has several bugs.
There is an active community out there that fixes bugs and improves
asn1c. Let's use their version.
