    Add io_select_timeout to the io interface
    
    This change fixes a problem that can occur with non-blocking (and also
    blocking for very short times) select/poll calls. The problem occurs because
    the timeout is implemented at the client side. For a non-blocking call, this
    means that (depending on the code path taken in the C library) the client
    could get a timeout without a full RPC round-trip to the server. Moving the
    implementation of the timeout to the servers guarantees a full round-trip,
    and correct results for non-blocking calls.
    
    The modifications in this change depend on the availability of the recently
    added pthread_hurd_cond_timedwait_np function in libpthread.
