This patch introduce a mechanism for running dpdk application with parameters
provided by configuration file. New API for cfgfile library allows to create
a cfgfile at runtime, add new section and add entry in a section - opens up
the possibility to have applications dynamically build up a proper DPDK
configuration, rather than having to have a pre-existing one.

A new API for EAL takes a config file data type - either loaded from file,
or built up programmatically in the application - and extracts DPDK parameters
from it to be used when eal init is called. This allows apps to have an alternative
method to configure EAL, other than via command-line parameters.

Testpmd application is used to the demonstrate the new eal API.
If a --cfgfile-path <path> option is passed into command line non EAL section,
then the file is loaded and used by app. If a file called config.ini is present
in current working directory, and no --cfgfile-path option is passed in,
config.ini file will be loaded and used by app.

Currently *.ini file format is supported, but we would like to demonstrate in
v2 how alternative config file formats could be used. Other work planned for v2:
support for subsections – allowing to pass i.e. [DPDK.vdev0] and its parameters,
cleanup to EAL API and testpmd.
