    dirmngr: Add new debug flag "extprog"
    
    * dirmngr/dirmngr.h (DBG_EXTPROG_VALUE, DBG_EXTPROG): New macros.
    * dirmngr/dirmngr.c (debug_flags): Add flag "extprog".
    (handle_connections): Use a macro instead of -1 for an invalid socket.
    * dirmngr/loadswdb.c (verify_status_cb): Debug the gpgv call.
