  40  * m_functions execute protocol messages on this server:
  41  *
  42  *    cptr    is always NON-NULL, pointing to a *LOCAL* client
  43  *            structure (with an open socket connected!). This
  44  *            identifies the physical socket where the message
  45  *            originated (or which caused the m_function to be
  46  *            executed--some m_functions may call others...).
  47  *
  48  *    sptr    is the source of the message, defined by the
  49  *            prefix part of the message if present. If not
  50  *            or prefix not found, then sptr==cptr.
  51  *
  52  *            (!IsServer(cptr)) => (cptr == sptr), because
  53  *            prefixes are taken *only* from servers...
  54  *
  55  *            (IsServer(cptr))
  56  *                    (sptr == cptr) => the message didn't
  57  *                    have the prefix.
  58  *
  59  *                    (sptr != cptr && IsServer(sptr) means
  60  *                    the prefix specified servername. (?)
  61  *
  62  *                    (sptr != cptr && !IsServer(sptr) means
  63  *                    that message originated from a remote
  64  *                    user (not local).
  65  *
  66  *            combining
  67  *
  68  *            (!IsServer(sptr)) means that, sptr can safely
  69  *            taken as defining the target structure of the
  70  *            message in this server.
  71  *
  72  *    *Always* true (if 'parse' and others are working correct):
  73  *
  74  *    1)      sptr->from == cptr  (note: cptr->from == cptr)
  75  *
  76  *    2)      MyConnect(sptr) <=> sptr == cptr (e.g. sptr
  77  *            *cannot* be a local connection, unless it's
  78  *            actually cptr!). [MyConnect(x) should probably
  79  *            be defined as (x == x->from) --msa ]
  80  *
  81  *    parc    number of variable parameter strings (if zero,
  82  *            parv is allowed to be NULL)
  83  *
  84  *    parv    a NULL terminated list of parameter pointers,
  85  *
  86  *                    parv[0], sender (prefix string), if not present
  87  *                            this points to an empty string.
  88  *                    parv[1]...parv[parc-1]
  89  *                            pointers to additional parameters
  90  *                    parv[parc] == NULL, *always*
  91  *
  92  *            note:   it is guaranteed that parv[0]..parv[parc-1] are all
  93  *                    non-NULL pointers.
