/* Load parameters.
*
* This module provides suitable callback functions for the params
* module. It builds the internal table of section details which is
* then used by the rest of the server.
*
* To add a parameter:
*
* 1) add it to the global_vars or local_vars structure definition
* 2) add it to the parm_table
* 3) add it to the list of available functions (eg: using FN_GLOBAL_STRING())
* 4) initialise it in the Defaults static stucture
*
* Notes:
* The configuration file is processed sequentially for speed. 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!
