Support beam index for LiteON FR2 RU that needs per symbol section in CP packets
This branch supports beam index for LiteOn FR2 RU and others. It adds
the support of beam index for LiteOn RU that uses per-symbol CP packet
and is a sequel of MR !3605 (merged) that supports beam index for RU
that uses per-slot CP packets.
A. To support LiteOn FR2 RU, the following are needed.
a. Per symbol beamforming. Need separate section for each symbol on CP packet.
b. Handle these two bugs:
- section ID on UP packet is set wrongly to 13 for all sections
- prach eAxC offset starts from 0 instead of from last antenna port
number used by other channels.
B. Implementation
a. set fh_config->RunSlotPrbMapBySymbolEnable based on the setting in the configuration file
- if disable, the existing per-slot scheme is run on xran.
- if enable, RunSlotPrbMapBySymbolEnable mode is on in xran so that xran
will generate PrbElm per symbol (aka total of 14)and perform
per-symbol processing on the corresponding PrbElm.
b. set fh_config->LiteOnIgnoreUPSectionIdEnable based on the setting in
the configuration file if enable, handle 2 "features" of Liteon:
- To handle the section_id = 13 issue on Liteon where section ID is set
wrongly to 13 for all sections
- To handle the prach eAxC offset issue on Liteon where it starts from 0
instead of from the end of last antenna port number
c. if fh_config->RunSlotPrbMapBySymbolEnable, OAI FHI
- invoke xran_fh_rx_read_slot_BySymbol() instead of xran_fh_rx_read_slot()
- invoke xran_fh_tx_send_slot_BySymbol() instead of xran_fh_tx_send_slot()
C. Testing
a. Command to test benetel RU
sudo LD_LIBRARY_PATH=.:$DPDK_INST/lib/x86_64-linux-gnu/ ./nr-softmodem -O /etc/ran_development/CONFs/gnb.sa.band77.273prb.fhi72.4x4-benetel550_c0.conf --thread-pool 21,22,23,24,25,26,27,28

[FHI72 M-plane] Update the M-plane support to v16.01
- retrieve the additional hardware states (oper-state, admin-state,
availability-state) and update according to the received notifications
- properly configure MIMO mode if a RU supports
- update the yang models to v16.01
- tested with Benetel v1.4.1, and added an example run in the M-plane doc
Note: backwards compatible with M-plane v05.00
Also, memory leakages fixed cause by ru_session_list_t, and xml functions
xmlReadMemory() and xmlNodeGetContent().
saves about 600MB of memory allocation
Move the definition of PRACH items and the PRACH list to the
defs_nr_commons.h file.
Do not re-write the entire structure in nr_schedule_rx_prach(), as it is
quite large now.
This struct is used in multiple source files.
Previously, when stopping the nr-softmodem, the ru_session_list "disappears"
and the M-plane wasn't terminated properly (num_rus = 0 even though DU connected to at least one RU).
Initialize ru_info structure with beam information, and set beams on TX
direction. Initialize the number of antennas for both RX/TX in both
cases for completeness.
Introduced a parameter start_up_timing which indicates if PM activation is supported during the start-up
procedure. We initialize this parameter, based on the vendor.
Notification interval is set to 10s.
Get xran stats in the trx_oran_get_stats function
and use trx_oran_get_stats upon stopping and ending RF.

- if RU(s) are not well configured, disconnect immediately and stop the DU
- if all RUs are well configured, proceed with waiting until ready. The RU is
ready when the carriers are activated. Either the RU already has preconfigured
carriers (previous M-plane client configured), or the DU has to wait until receives
the notifications.
The parent commit cleans up and groups oai_exit in one place,
nr-softmodem-common.h. Therefore, this 5G file is included in the 4G
defs_common.h (at least it's mostly 4G), which is not nice. Instead,
define oai_exit also in 4G softmodem-common.h, and include this in
defs_common.h. Remove the cyclic inclusion of defs_common.h in
softmodem-common.h, and resolve all subsequent errors around unknown
types and extern definition mismatches.
- removed some whitespace noise.
- cleaned up CMakeLists.txt
- reintegrated task_manager.c into thread-pool.c
- cleaned up some unnecessary code
