lz4.c : copy macros follow memcpy() arguments convention
Small coding style modifications, hinted by cppCheck. 

Corrected a bug into the compact XXH32() function, which affects Block Checksum results. Update is recommended if you use Block Checksum with lz4c. (Note : block checksum is disabled by default). Thanks Adrien Grand for detailed bug tracking and fixing.
Corrected a bug affected Heapmode version of LZ4_compress() (Note : heapmode is disabled by default)
