Added : LZ4 Streaming Format specification (v1.3)

Added : LZ4c command-line utility, supporting the new streaming format
Added : xxhash library
Removed : lz4demo is now replaced by lz4.c
Removed : a few level 4 warnings (issue 64)
Updated : makefiles

 LZ4_compress() :

-    Compresses 'isize' bytes from 'source' into 'dest'.

+    Compresses 'input_size' bytes from 'source' into 'dest'.

     Destination buffer must be already allocated,

     and must be sized to handle worst cases situations (input data not compressible)

     Worst case size evaluation is provided by function LZ4_compressBound()

-

-    isize  : is the input size. Max supported value is ~1.9GB

+    input_size : Max supported value is ~1.9GB

     return : the number of bytes written in buffer dest

-

+             or 0 if the compression fails

 

 LZ4_uncompress() :

-    osize  : is the output size, therefore the original size

+    output_size : is the original (uncompressed) size

     return : the number of bytes read in the source buffer (in other words, the compressed size)

-             If the source stream is malformed, the function will stop decoding and return a negative result, indicating the byte position of the faulty instruction

-             This function never writes outside of provided buffers, and never modifies input buffer.

-    note : destination buffer must be already allocated.

-           its size must be a minimum of 'osize' bytes.
