/****** qmaster/sge_qmaster_main/main() ****************************************
* NAME
* main() -- qmaster entry point
*
* SYNOPSIS
* int main(int argc, char* argv[])
*
* FUNCTION
* Qmaster entry point.
*
* NOTE: The main thread must block all signals before any additional thread
* is created. Failure to do so will ruin signal handling!
*
* INPUTS
* int argc - number of commandline arguments
* char* argv[] - commandline arguments
*
* RESULT
* 0 - success
*
* NOTES
* We check whether 'SGE_ROOT' is set before we daemonize. Once qmaster is
* a daemon, we are no longer connected to a terminal and hence can not
* output an error message to stdout or stderr.
*
* We need to inovke 'prepare_enroll()' *before* the user id is switched via
* 'become_admin_user()'. This is because qmaster must be able to bind a so
* called reserved port (requires root privileges) if configured to do so.
