The --record-core-cycles option already accounts for busy cycles. One
turn of packet_fwd_t is considered "busy" if there was at least one
received or transmitted packet.
Rename core_cycles to busy_cycles in struct fwd_stream to make it more
explicit. Add total_cycles to struct fwd_lcore. Add cycles accounting in
noisy_vnf where it was missing.
When --record-core-cycles is specified, register a callback with
rte_lcore_register_usage_cb() and update total_cycles every turn of
lcore loop based on a starting tsc value.
In the callback, resolve the proper struct fwd_lcore based on lcore_id
and return the lcore total_cycles and the sum of busy_cycles of all its
fwd_streams.
This makes the cycles counters available in rte_lcore_dump() and the
lcore telemetry API:
testpmd> dump_lcores
lcore 3, socket 0, role RTE, cpuset 3
lcore 4, socket 0, role RTE, cpuset 4, busy cycles 1228584096/9239923140
lcore 5, socket 0, role RTE, cpuset 5, busy cycles 1255661768/9218141538
