It supports one new eal long option '--lcores' for EAL thread cpuset assignment.
The format pattern:
--lcores='<lcores[@cpus]>[<,lcores[@cpus]>...]'
lcores, cpus could be a single digit/range or a group.
'(' and ')' are necessary if it's a group.
If not supply '@cpus', the value of cpus uses the same as lcores.
e.g. '1,2@(5-7),(3-5)@(0,2),(0,6),7-8' means starting 9 EAL thread as below
lcore 0 runs on cpuset 0x41 (cpu 0,6)
lcore 1 runs on cpuset 0x2 (cpu 1)
lcore 2 runs on cpuset 0xe0 (cpu 5,6,7)
lcore 3,4,5 runs on cpuset 0x5 (cpu 0,2)
lcore 6 runs on cpuset 0x41 (cpu 0,6)
lcore 7 runs on cpuset 0x80 (cpu 7)
lcore 8 runs on cpuset 0x100 (cpu 8)

Help is printed with -h or --help.
Help is also printed for an unknown option.
This was broken since the rework of options.

Options listing in usage help was a mess.
The main usage line is fixed and shorter.
The options in usage output are logically sorted (cpu/mem/dev/proc),
aligned and lightly reworded.
The options in declarations are alphabetically sorted.
Code in swith statement is not moved.

Some adjustments are done after options parsing and are common
to Linux and BSD.
Remove process_type adjustment in rte_config_init() because
it is already done in eal_parse_args().
eal_proc_type_detect() is kept duplicated because it open a
file descriptor which is used later in each eal.c.

No need to have duplicated check for common options.
Some flags are set for options -c and -m in order to simplify the
checks.
