After having removed eth_params_t from all L2/L3 files, we can reduce
the scope of common_lib.h, and remove the include from many files.

Map P-RNTI scheduled DLSCH to the UE DLSCH receive indication flow so
paging traffic is also classified like DLSCH together with C-RNTI.
Changes:
- Set `dlsch0->rnti_type` from DLSCH RNTI in scheduled response, using
`TYPE_P_RNTI_` when RNTI is `P_RNTI`
- Extend `nr_ue_dlsch_procedures()` RX indication mapping to include
`TYPE_P_RNTI_` in the DLSCH indication case

- make internal links relative where applicable
- delete link to the wiki, as the documentation is in the main repo, not
the wiki
- remove some "example in oai code" as the examples either don't exist,
or are not in that place, and we can reasonably expect people to grep

Separate nfapi_p5.c into LTE and NR implementations
This MR aims to separate the implementation of the nFAPI P5 and P7
message pack/unpack procedures into 4G and 5G implementations.
This will be followed up with a separation of the VNF and PNF
implementations in 4G and 5G versions as well.
The final goal is to achieve a clean separation between 4G and 5G,
foregoing the need to compile 4G components when we only want to compile
5G ones.

Copying large struct one element at a time generates much more assembly code
than memcpy and the code becomes less maintainable. This commit copies parts of
structs using memcpy.

even if 2 codewords are currently not supported and not tested, the way UE handled the possibility of having 2 codewords was messy, in between support and non-support
the intention of this MR is to cleanup the code more than extend the support

bit_len / 8 + 1 overcounts by 1 when bit_len is an exact multiple of 8.
Replace with (bit_len + 7) / 8 across all pack/unpack sites for PUSCH
and PUCCH 2/3/4 SR/HARQ/CSI payloads, and in the utility functions
(eq, copy, size calculator, dump) and unit test fill functions.
Fixes UCI.indication unpack failure against cuBB when CSI-1 report
is 8 bits.

Further unused arguments cleanup
More fixes for unused function arguments (see #1057),
add_compile_options(-Wunused-parameter) added in folders:
- nfapi
- openair2
- openair3
- USRP
- rfsimulator
Remove a lot of unused code, defines, and config options
Remove unused header files and defines.
Slightly clean up gnb_config.c by removing all _IDX variables. Remove
these unused parameters:
- MACRLCs.[0].num_cc
- MACRLCs.[0].local_n_portc
- MACRLCs.[0].remove_n_portc
- MACRLCs.[0].remote_s_portc
- MACRLCs.[0].remote_s_portd
- L1s.[0].num_cc
- L1s.[0].local_n_portc
Remove the gNB_MAC_INST.eth_params_s, since it's only purpose is to
store what can be on the stack.
For the Aerial log message, don't print an empty prefix but what is
actually used for Aerial.

Configure DigitalBeamTable in OAI and pass down to Aerial L1
With this MR it will be possible to define a Beamtable in OAI and pass it down
to a L1 (Aerial or OAI) which then will either use them locally to apply
static beamforming (Split 8 with USRP) or pass them down to the RU using 7.2
split with Section Extension 1.
Reduce number of mutex locking in MAC->RLC direction
Currently, the scheduler locks RLC for each operation. Concretely
- for RLC status indication (to get amount of bytes per LC), it locks per LC
- for RLC indication (UL traffic), it locks for each MAC SDU of which there can
be multiple in a TB
- for RLC data req (getting data from RLC to put into a transport block), it
locks for each LCID and PDU to get.
This can have a certain overhead, because we need to re-lock RLC multiple times
instead of once (per operation above). In this MR, rework the interfaces such
that it is possible to get all information/data in a single lock-unlock cycle,
which should also help with "spikes" of scheduler times (in some scenarios, it
seems the scheduler takes longer than 0.5ms, and while it's not only locking,
re-locking might contribute), and an increase of number of UEs (e.g., instead
of doing 3 * N UEs lock cycles for getting status of SRB1, SRB2, DRB1, we do
only N times). Concretely, for each UEs RLC status indication, we lock once,
only once per LCID when filling a TB (in particular for LCID 4, on high
throughput, it might be many times), and only once per UL TB (for the common
case of UL data).
Minor fixes include the increase of the Aerial VNF thread priority, and reducing
the maximum RLC indication size to reduce excessive computation (we can't have
1MB in one TB, it is too much).
Remove L1 dependence from NR band number
L1 band information relied on get_band function that couldn't provide an
unambiguous result. Also there is no SCF compliant parameter for L1 and
generally we don't really need that information in L1.
The MR also remove a RU section that used nr_band but was never really
accessed in NR.
Change Aerial to pack directly in nvIPC message buffer
This MR changes the Aerial pack/send procedures to pack the messages
directly into the nvIPC message buffers.
This saves the use of some memcopy calls, as well as clean up the code.
The P7 message packing/send is now only handled in the file
`fapi_nv_p7.c`
Add 3 functions in fapi_nvIPC.c to allow message allocation, release and
send from fapi_vnf_p7.c
Add 2 functions to access the memory pool sizes allocated from nvIPC, as
we can't use sizeof to report the buffer size to the packing functions
Remove now unused aerial_send_P5_msg , aerial_send_P7_msg and
aerial_send_P7_msg_with_data functions
Now Aerial only has one function to handle sending P5 and another to
send P7 messages
Remove fapi_phy_api_msg from fapi_nvIPC.h as it is duplicated in
nr_fapi.h
Prevent the PNF from sending P7 messages after sending a STOP.indication
Upon stopping the PNF, when sending the STOP.indication to the VNF, set
pnf_p7->terminate to 1.
Add a check on the PNF P7 send functions to not send a message after
pnf_p7->terminate is set.
This prevents the PNF from sending SLOT.indications after stopping,
which sometimes was causing the VNF to process a SLOT.indication after
it had received the indication to STOP.
Also, this MR adds a sanity check on the VNF P7 message handler to
ignore any P7 messages it receives after having it's own terminate flag
set to 1
This MR closes issue #1045
