89767cc280 Small speed improvement (compression & decompression), Thanks Maciej Adamczyk for suggestion 
Fixed : LZ4_uncompress_unknownOutputSize(), now protected against a malicious attack type, where a crafted input deliberately attempts to make it read outside of input buffer. Thanks Steinar H. Gunderson for report.

Minor : bench.c : selectable block size
