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.

Add CMake option LZ4_BUILD_CLI. 
Defaults to ON so nothing changes, but it can be set to OFF so that the
CLI is not built at all, only the library.

b223f11b21 ubsan: make pointer overflow recoverable 
the way `base` is used must allow 2-complement address overflow.
`base` is effectively a virtual pointer, never dereferenced directly.
What matters is `base + index`.
This is the address that will be dereference and must be valid (it is properly validated).

c5d6f8a8be fix #783 
LZ4_decompress_safe_partial()
now also supports a scenario where
nb_bytes_to_generate is <= block_decompressed_size
And
nb_bytes_to_read is >= block_compressed_size.

Previously, the only supported scenario was
nb_bytes_to_read == block_compress_size.

Pay attention that,
if nb_bytes_to_read is > block_compressed_size,
then, necessarily, it requires that
nb_bytes_to_generate is <= block_decompress_size.
If both are larger, it will generate corrupted data.
