Review request for KDE Frameworks and Sune Vuorela.


Repository: karchive


Description (updated)
-------

Handle multiple gzip streams
    
    If kgzipfilter notices that zlib didn't read all the data, it tries to
    re-init the stream and read the rest of the buffer. This is tested by
    the unit test from Sune. The case where there's more than two streams
    available in the current buffer is tested in a unit test added
    separately.
    
    If the split between the streams falls right between two buffers, we
    need KCompressionDevice to notice that there's data left and try to
    continue decompressing. This is easy to test by setting BUFFER_SIZE to
    the size of the first stream in the unit test data (28 bytes).
