/*
 *  Load parameters.
 *
 *  This module provides suitable callback functions for the params
 *  module. It builds the internal table of service details which is
 *  then used by the rest of the server.
 *
 * To add a parameter:
 *
 * 1) add it to the global or service structure definition
 * 2) add it to the parm_table
 * 3) add it to the list of available functions (eg: using FN_GLOBAL_STRING())
 * 4) If it's a global then initialise it in init_globals. If a local
 *    (ie. service) parameter then initialise it in the sDefault structure
 *
 *
 * Notes:
 *   The configuration file is processed sequentially for speed. It is NOT
 *   accessed randomly as happens in 'real' Windows. For this reason, there
 *   is a fair bit of sequence-dependent code here - ie., code which assumes
 *   that certain things happen before others. In particular, the code which
 *   happens at the boundary between sections is delicately poised, so be
 *   careful!
