  21  *  Load parameters.
  22  *
  23  *  This module provides suitable callback functions for the params
  24  *  module. It builds the internal table of service details which is
  25  *  then used by the rest of the server.
  26  *
  27  * To add a parameter:
  28  *
  29  * 1) add it to the global or service structure definition
  30  * 2) add it to the parm_table
  31  * 3) add it to the list of available functions (eg: using FN_GLOBAL_STRING())
  32  * 4) If it's a global then initialise it in init_globals. If a local
  33  *    (ie. service) parameter then initialise it in the sDefault structure
  34  *
  35  *
  36  * Notes:
  37  *   The configuration file is processed sequentially for speed. It is NOT
  38  *   accessed randomly as happens in 'real' Windows. For this reason, there
  39  *   is a fair bit of sequence-dependent code here - ie., code which assumes
  40  *   that certain things happen before others. In particular, the code which
  41  *   happens at the boundary between sections is delicately poised, so be
  42  *   careful!
