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