 * \brief Bootstrap the fossology php library.
 *  - Determine SYSCONFDIR
 *  - parse fossology.conf
 *  - source template (require_once template-plugin.php)
 *  - source common files (require_once common.php)
 *
 * The following precedence is used to resolve SYSCONFDIR:
 *  - $SYSCONFDIR path passed in ($sysconfdir)
 *  - environment variable SYSCONFDIR
 *  - ./fossology.rc
 *
 * Any errors are fatal.  A text message will be printed followed by an exit(1)
 *
 * \param string $sysconfdir Typically from the caller's -c command line parameter
 *
 * \return mixed the $SysConf array of values.  The first array dimension
 * is the group, the second is the variable name.
 * For example:
 *  -  $SysConf[DIRECTORIES][MODDIR] => "/mymoduledir/
 *
 * The global $SYSCONFDIR is also set for backward compatibility.
 *
 * \Note Since so many files expect directory paths that used to be in pathinclude.php
 * to be global, this function will define the same globals (everything in the
 * DIRECTORIES section of fossology.conf).
