OAI is riddled with boolean_t, FALSE, TRUE, etc. This makes no sense, as
there is a standard bool type, and could lead to nasty bugs if a
definition of a bool is non-standard (0 == false, true == !false). This
commit removes all non-standard bools in the whole project.

I rewrote a bit the function Gtpv1uHandleGpdu(). It might have been
done wrongly.
To be tested and fixed if needed.
To redo the merge, if needed:
git checkout 9b2a163ebb
git merge 5ea828e149
Instead of NULL RAND value check, added the flag to indicate if the
AUTH process started. The flag is used manage the timer handling
for authentication process when stored RAND values is same as received
RAND value in AUTH_REQ.
It was observed in simulation test the OAI UE always sends the sucessful
AUTH_RES when the AUTH_REQ has the RAND value "0". This opens a back door
in the authentication process.
The code is modified to fix this issue in OAI UE.
1. Removed SDAP struct from protocol context.
2. Added configuration for the SDAP.
3. SDAP doesn't use pdcp_entities, the values come from function arguements.
4. Make nr_pdcp_ue_manager accessible from SDAP.
5. Avoid using the PDCP locking mechanism in SDAP.
6. Removed nr_pdcp_find_entity_sdap function.
7. Rename dummy eNB function to make GTP compile (no SDAP).
8. Fix: Regression issues with LTE
9. Fix: Regression issues with NR CU/DU
-After that no DL traffic is getting blocked at the Accelleran CU for low values of throughput
-Remaining to remove the hardcoded value of buffer availability and report the actual value from the DU.
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.
