DEPRECATED
SYNOPSIS
        void receive_imp(string host, string msg, int hostport)

DESCRIPTION
        Handle a received IMP message.

        This function is called for every message received on the IMP
        port. Usually it is passed on to some object that handles
        inter mud communications.

        The driver first calls receive_udp(). If that method doesn't exist
        and if the driver is compiled with USE_DEPRECATED, it will then
        call receive_imp().

HISTORY
        The 'hostport' argument was added in 3.2.1.
    LDMud 3.2.9 renamed this method from receive_imp(); this old version
      is supported if the driver is compiled with USE_DEPRECATED.
