[PATCH v2 0/6] librte_cfgfile enhancements

[Allain Legacy <allain.legacy@windriver.com>]

This patchset includes some minor enhancements that we have developped for
our DPDK application.  We would like to contribute them upstream to help
ease adoption of the DPDK by anyone looking for this type of
functionality.  The commit logs on each patch should be self-sufficient in
explaining the intent and purpose.

v2:
* Added unit tests for the cfgfile library in the initial patch of the
  series and then added additional tests in subsequent patches where
  appropriate.  These will not run unless the following config parameter is
  set and additional packages are installed (e.g., libarchive-dev):
        CONFIG_RTE_APP_TEST_RESOURCE_TAR=y
* Reworked the configurable comment character patch to allow specifying a
  different character at runtime rather than build time.  Used a separate
  API to avoid affecting existing users or users that choose not to
  leverage the extended API.  Used a "parameters" structure to pass
  additional arguments rather than adding more arguments to the function to
  allow expansion in the future with minimal impact on existing users.
* Dropped the patch to initialize the cfg structure because the segfault
  that this was trying to address was already fixed by 2 earlier commits
  which we did not have in our development environment.  I realized this
  while trying to add unit tests to catch the segfault case.
* Fixed the doxygen comments related to the RTE_CFG_GLOBAL_SECTION patch
* Added an additional patch to allow parsing a key with an empty value
  (i.e., "key=").  I realized that I had forgotten to include this in my
  first patchset.
