When allocating multi segmented buffers, and in case there is
a remainder in total buf len, the actual job len might be more
than expected job_len.
This adds additional space in the mbuf in the multi seg case,
to allow the remaining memory to be stored in one segment.

Depending on number of jobs specified on command line, part of the
data buffer may not get searched, resulting in incorrect number of
matches being reported.
Additional change to ensure the "All Matches" summary outputs the
correct match start locations in the supplied data buffer.

Some applications were printing useless messages with rte_exit()
after showing the help. Using exit() is enough in this case.
Some applications were using a redundant printf or fprintf() before
calling rte_exit(). The messages are unified in a single rte_exit().
Some rte_exit() calls were missing a line feed or returning a wrong code.

Up to this commit the regex application was running with multiple QPs on
a single core. This commit adds the option to specify a number of cores
on which multiple QPs will run.
A new parameter 'nb_lcores' was added to configure the number of cores:
--nb_lcores <num of cores>.
If not configured the number of cores is set to 1 by default. On
application startup a few initial steps occur by the main core: the
number of QPs and cores are parsed. The QPs are distributed as evenly
as possible on the cores. The regex device and all QPs are initialized.
The data file is read and saved in a buffer. Then for each core the
application calls rte_eal_remote_launch() with the worker routine
(run_regex) as its parameter.

Up to this commit the regex application used one QP which was assigned a
number of jobs, each with a different segment of a file to parse. This
commit adds support for multiple QPs assignments. All QPs will be
assigned the same number of jobs, with the same segments of file to
parse. It will enable comparing functionality with different numbers of
QPs. All queues are managed on one core with one thread. This commit
focuses on changing routines API to support multi QPs, mainly, QP scalar
variables are replaced by per-QP struct instance. The enqueue/dequeue
operations are interleaved as follows:
enqueue(QP #1)
enqueue(QP #2)
...
enqueue(QP #n)
dequeue(QP #1)
dequeue(QP #2)
...
dequeue(QP #n)
A new parameter 'nb_qps' was added to configure the number of QPs:
--nb_qps <num of qps>.
If not configured, nb_qps is set to 1 by default.

getopt_long() parses command-line arguments. One of its arguments
'longopts' is a pointer to the first element of an array of struct
option. The last element of the array has to be filled with zeros
to mark the end of options. For example:
struct option longopts[] = {
{ "help", 0, 0, ARG_HELP},
....
/* End of options */
{ 0, 0, 0, 0 }
};
This commit adds the last element. Prior to this commit getopt_long()
continued parsing beyond the longopts[] array which occasionally caused
segmentation faults.

Following the new RegEx class.
There is a need to create a dedicated test application in order to
validate this class and PMD.
Unlike net device this application loads data from a file.
This commit introduces the new RegEx test app.
The basic app flow:
1. Configure the RegEx device to use one queue, and set the rule
database, using precompiled file.
2. Allocate mbufs based on the requested number of jobs, each job will
i get one mbuf.
3. Enqueue as much as possible jobs.
4. Dequeue jobs.
5. if the number of dequeue jobs < requested number of jobs job to step
