Is forward seeking a capability of input plugins that I can always depend on existing
regardless of whether INPUT_CAP_SEEKABLE is set? Would be nice for me to get rid of the
skip_bytes routine in demux_wve if it is. A unified system for back seeking similar to
the mark() and reset() methods of java.io.InputStream would also be, IMHO, a good idea.
I would add a mark() function for setting a mark and simply allow back seeking up to the
mark. There would also need to be a clear() function for removing the mark. This would
also dispense with the need for preview buffers and be far more flexible. It would
simplify some the problems of data structure traversal that the lack of back seeking
brings. For example, reading an arbitrarily long null terminated string.
