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