commit 557be8c56b652751a1797f1ac1365f1ace38146a
Author: Alexander Barton 
Date:   Sat Aug 16 00:02:44 2008 +0200

    Get rid of INTRO_INFO structure again: we don't need it at all!

    All the required information is already stored in the CLIENT structure
    of new new connection, so pass this to Introduce_Client() and don't
    invent an unneeded new structure ...
