EAL -c option allows the user to enable any lcore in the system.
Often times, the user app wants to know 1st enabled core, 2nd
enabled core, etc, rather than phyical core ID (rte_lcore_id().)
The new API rte_lcore_index() will return an index from enabled lcores
starting from zero.

In current version, used cores can only be specified using a bitmask.
It will now be possible to specify cores in 2 different ways:
- Using a bitmask (-c [0x]nnn): bitmask must be in hex format
- Using a list in following format: -l <c1>[-c2][,c3[-c4],...]
The letter -l can stand for lcore or list.
-l 0-7,16-23,31 being equivalent to -c 0x80FF00FF

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.

Now that internal config structure is common to Linux and BSD,
we can have a common function to initialize it.

Identify all options through the getopt_long return value.
This way, we only need a big switch/case.
Indentation is broken to ease commit review (fixed in next commit).
