[PATCH 1/5] cfgfile: configurable comment character

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

The current cfgfile comment character is hardcoded to ';'.  This commit
introduces a configuration attribute to allow an application to select a
different character.  This is to ease adoption by applications that have an
existing configuration file which may use a different comment character.
For instance, an application may already have a configuration file that
uses the '#' as the comment character.
