CLI : corrected writing to NULL within Linux
Minor : several comments were updated

If you need to provide "isize" instead of "osize" to the decoder, please use LZ4_uncompress_unknownOutputSize(), which is safer.

Most of the change is due to a modification in the performance parameter (HASH_LOG) now set to 12, to match Intel L1 cache processors.
You can change it back to 17 to get back previous compression ratio.
AMD users are invited to try HASH_LOG = 13, since AMD L1 cache is twice larger.
git-svn-id: https://lz4.googlecode.com/svn/trunk@10 650e7d94-2a16-8b24-b05c-7c0b3f6821cd
New function : LZ4_uncompress_unknownOutputSize : secure but slower version which also guess the size of data to be decoded
The demo file compression program (main.c) is updated to use these new functions
LZ4_decode is still supported but in deprecated status, due to its vulnerability to malicious buffer overflow scenario
