a296839802 changed LZ4_calloc() to a 2-arguments signature 
to remain similar to stdlib's calloc().

Updated test to use c++ compiler for stricter signature check.

52646e8d75 first proposal for LZ4_USER_MEMORY_FUNCTIONS 
makes it possible to replace at link time
malloc, calloc and free
by user-provided functions
which must be named LZ4_malloc(), LZ4_calloc() and LZ4_free().

2964b8a6f6 fix #874 
coverity reported a warning regarding a memcpy() overwrite.
This is a false positive (the memory area is large enough),
but it's true that it's not trivial to determine (encompassing struct),
and it's proper anyway to only memcpy() just the right amount of data.

e7fe105ac6 fix efficiency of LZ4_compress_HC_destSize() 
LZ4_compress_HC_destSize() had a tendency
to discard its last match when this match overflowed specified dstBuffer limit.
The impact is generally moderate,
but occasionally huge,
typically when this last match is very large
(such as compressing a bunch of zeroes).

Issue #784 fixed for both Chain and Opt implementations.

Added a unit test suggested by @remittor checking this topic.
