uncompress_unknownOutputSize fails to uncompress long random streams compressed with compressHC #28

Hi,

I am doing some tests with lz4 trunk and I am having trouble with 
uncompress_unknownOutputSize and compressHC. More specifically, I am testing it 
on random char streams (same likelyhood for every char in the [0, 256[ range), 
then compress with compressHC and uncompress_unknownOutputSize always returns 
an uncompressed size of 4096 when the size of the original stream size is ~4200 
or more.

On the other hand, it works perfectly fine:
 - when the original size of the stream is < 4000,
 - when I decompress with uncompress, whatever the original stream size is,
 - with a non-random stream, whatever the original stream size is.
