lz4 (& lz4c) display version number
Fix : Sun Studio : compatible #pragma directive (issue 81)
Fix : compatible with Objective-C (iOS) (issue 79)
Fix : minor warnings using Visual Studio x64 (issue 80)
Changed : source file lz4c.c renamed lz4cli.c

27efcd4d45 Removed dependency to "lz4_encoder.h" and "lz4hc_encoder.h"
Improved speed of LZ4_decompress_fast() with GCC
Improved speed of LZ4_decompress_safe() for 32-bits
Made the fast LZ4 compression compatible with low-memory systems (buffer address < 64K). Thanks Francois Gretief for report and suggestion.
Makefile : added fuzzer32
Makefile : added fullbench32
fullbench : added ability to select one specific function to benchmark
lz4.c : copy macros follow memcpy() arguments convention
Small coding style modifications, hinted by cppCheck.

002a93473d Corrected issue 70, 'pack' instruction on IBM AIX
Added : fullbench : can select compression tests or decompression tests
Removed extern inline, for compatibility with GNU89, as reported by Maciej Adamczyk
lz4.c : made forceinline more explicit
Decompression : corrected corner case behaviors (inputSize == 0 and outputSize == 0), thanks Adrien for detailed suggestions
Makefile : Removed -march=native parameter, due to incompatibility with some GCC versions

b1e707f772 - Corrected issue 31 : LZ4 correctly accepts compressing data when the output buffer has exactly the required size (it was a bit over-cautious in previous version).
- Added : a fuzzer tool
Thanks to Andrew Mahone, for contribution on both points

make lz4demo32
