In the case that the cores are isolated, if "-l" or "-c" parameter is not
added, the cores will not be enabled and can not launch worker function
correctly. In the meanwhile, no error information is reported.
For example:
totally CPUs:16
isolated CPUs:1-8
command: sudo gdb -args ./dpdk-eventdev_pipeline --vdev event_sw0 \
-- -r1 -t1 -e4 -w F00 -s4 -n0 -c32 -W1000 -D
cores information:
rte_config->lcore_role = {ROLE_RTE, ROLE_OFF, ROLE_OFF, ROLE_OFF,
ROLE_OFF, ROLE_OFF, ROLE_OFF, ROLE_OFF,
ROLE_OFF, ROLE_RTE, ROLE_RTE, ROLE_RTE,
ROLE_RTE, ROLE_RTE, ROLE_RTE, ROLE_RTE}
output information:
...
[main()] lcore 9 executing worker, using eventdev port 0
[main()] lcore 10 executing worker, using eventdev port 1
[main()] lcore 11 executing worker, using eventdev port 2
This is because "RTE_LCORE_FOREACH_WORKER" chooses the enabled core. In
the case that the cores are isolated, "the lcore_role" flag of isolated
cores are set as "ROLE_OFF" by default(not enabled). So if we choose
these isolated cores as workers, "RTE_LCORE_FOREACH_WORKER" will ignore
these cores and not launch worker functions on them.
To fix this, add "-l" parameters to doc and add lcore enabled check.

Replace -w / --pci-whitelist with -a / --allow options
and --pci-blacklist with --block.
The -b short option remains unchanged.
Allow the old options for now, but print a nag
warning since old options are deprecated.

While make has been deprecated for DPDK, it's still applicable for
some example apps to be built standalone, this patch adjusts the
guides to take that into consideration.
