app/regex: measure performance per queue pair
Up to this commit measuring the parsing elapsed time and Giga bits per
second performance was done on the aggregation of all QPs (per core).
This commit separates the time measurements per individual QP.

app/regex: support multiple cores
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.

app/regex: read data file once at startup
Up to this commit the input data file was read from scratch for each QP,
which is redundant. Starting from this commit the data file is read only
once at startup. Each QP will clone the data.

app/regex: support multiple queue pairs
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.
