** exit_client
** This is old "m_bye". Name changed, because this is not a

**
** This function exits a client of *any* type (user, server, etc)
** from this server. Also, this generates all necessary prototol
** messages that this exit may cause.
**
** 1) If the client is a local client, then this implicitly
** exits all other clients depending on this connection (e.g.
** remote clients having 'from'-field that points to this.
**
** 2) If the client is a remote client, then only this is exited.
**
** For convenience, this function returns a suitable value for
** m_funtion return value:
**
** FLUSH_BUFFER if (cptr == sptr)
** 0 if (cptr != sptr)
**
** Parameters:
**
** aClient *cptr
** The local client originating the exit or NULL, if this
** exit is generated by this server for internal reasons.
** This will not get any of the generated messages.
** aClient *sptr
** Client exiting
** aClient *from
** Client firing off this Exit, never NULL!
** char *comment
