/*
* 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!
