    prefer avio_check() over url_exist() · 55815edc

    The problem with url_exist() is that it tries to open a resource in
    RDONLY mode. If the file is a FIFO and there is already a reading
    client, the open() call will hang.
    By using avio_check() with access mode of 0, the second reading
    process will check if the file exists without attempting to open it,
    thus avoiding the lock.
    Fix issue #1663.
