Implementation of STOP exchange
This implements the STOP.request/indication for all 3 transport mechanisms, the
VNF will send the STOP.request to the PNF, indicating it will disconnect, and
await a STOP.indication from the PNF
The WLS VNF is reworked to be able to start before the PNF, by calling call
rte_eal_init and rte_dev_probe to determine if dpdk has been initialized
properly, before calling rte_eal_init in the intended process when it is
appropriate to do so

This allows access to the VNF configuration in the various transport mechanisms straight from config, without this, the transport specific thread would cause a segmentation fault when trying to access the pack/unpack function pointers.
Add 2 functions to access the P5 and P7 VNF structures, to avoid having to always cast user_data and p7_vnfs
Add nr_fapi_p5 library to the simulators common library for access to the utility function `copy_config_request`
Add dummy VNF/PNF functions to be referenced by lte-softmodem, before LTE and NR implementations of the VNF/PNF are separated
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.
