    Delete unused internal mechglue functions
    
    Get rid of gssint_get_mechanisms, gssint_mech_to_oid, and
    gssint_oid_to_mech, which constructed a list of mechanism names and
    mapped between mech names and OIDs.  These functions were only used by
    gss_inquire_mechs_for_name, which now uses gss_indicate_mechs instead.
