- Improved compression ratio
- Added special mode for small packet (<=64KB) which improves both compression and speed : LZ4_compress64kCtx()

This function explicitly handles the CTX memory structure.
It avoids allocating/deallocating memory between each call, improving performance when malloc is time-consuming.
+ Note : when memory is allocated into the stack (default mode), there is no "malloc" penalty.
+ Therefore, this function is mostly useful when memory is allocated into the heap (it requires increasing HASH_LOG value beyond STACK_LIMIT)
On first call : provide a *ctx=NULL; It will be automatically allocated.
On next calls : reuse the same ctx pointer.
