/**
* @brief
* pbs_loadconf - Populate the pbs_conf structure
*
* @par
* Load the pbs_conf structure. The variables can be filled in
* from either the environment or the pbs.conf file. The
* environment gets priority over the file. If any of the
* primary variables are not filled in, the function fails.
* Primary vars: pbs_home_path, pbs_exec_path, pbs_server_name
*
* @note
* Clients can now be multithreaded. So dont call pbs_loadconf with
* reload = TRUE. Currently, the code flow ensures that the configuration
* is loaded only once (never used with reload true). Thus in the rest of
* the code a direct read of the pbs_conf.variables is fine. There is no
* race of access of pbs_conf vars against the loading of pbs_conf vars.
* However, if pbs_loadconf is called with reload = TRUE, this assumption
* will be void. In that case, access to every pbs_conf.variable has to be
* synchronized against the reload of those variables.
*
* @param[in] reload Whether to attempt a reload
*
* @return int
* @retval 1 Success
* @retval 0 Failure
