Fix setup_time overflow in vnf processing thread, preventing gNB from stopping message processing once setup_time overflowed

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.

The SR ind was not properly being packed and unpacked.
The RX inidcation was not properly being allocated
prior to unpacking.
The freq_shift field was declared as a uint16_t but
push/pulled as a uint8_t.
Added MSG_TRUNC in the nfapi VNF recvfrom.

We seprarated out the large if block in the push/pull
of the UL_TTI_REQ fields to make it easier to read
and debug. Furthermore, we add in AsserFatals before
indexing in UL_TTI_REQ PDU list to ensure we are not
indexing past the end of the array.

- OPENAIR_DIR replaced with AWGN_RESULTS_DIR
- Copying UCI_2_3_4 PDU with rx'd PDU from proxy
- Reverting hacks/whitespace changes

This reverts commit 9a78b589.

The nfapi code releases dl_ttis and tx_data_reqs
if the buffer has data in it. In the proxy code we
overwrite this instead of dropping the packet.
