  lib: Add i_stream_nonseekable_try_seek()

This can be used by istreams to more easily implement seeking backwards when
it has to be done by first seeking back to offset 0 and reading from there.

After the stream size is found, seek back to original offset.

  lib-compression: deflate ostream - Use Z_FINISH on final flush

Nowadays we have o_stream_finish(), so we can differentiate between
intermediate flush and final flush. Using this allows istream-zlib to
cleanly see that the stream ends.
