It seems that the RA procedure in the gNB was modified so
the RAR is sent in a single tx_data_req. The emualted mode
was not previously handling this. We now only process the
PDU in the rx_ind that has a matching preamble. If any
other PDUs exist, we ignore them and only build Msg3 based
on this single matching RAR PDU.

Also, two bug fixes applied here in the emulate-l1 mode.

This struct is used to store the uplink 5G nFAPI
messages between the proxy and the gNB MAC layer.
The original OAI implementation utilizes a similarly
named variable (UL_info) to store the uplink 5G nFAPI
messages between the PHY and MAC layer. This commit
will utilize the original UL_info variable prior to
calling the handle functions. These changes allow us
to make minimal changes to the nFAPI handle functions
and modifies the NR_UL_Indication parent function instead.

This partially reverts commit bac8bc569c6a9ea073a17bff7fa487c8129cc114
and fixes nr_dlschsim, which did not compile without this commit.

We have to eat all the bytes, not only one.
We have to get the bit we want from the right buffer position.

Note: only one bit is supported from this "EPS network feature support",
not sure how to properly deal with it, so let's keep the code as it is.

This commit was made because the MAGMA MME sends "EPS network feature
support" to the UE in the NAS message "Attach Accept". OAI MME does not
send this. So the bug about size was not seen.
