acd75a1448 fixed a second memset() on NULL 
not sure why it only triggers now,
this code has been around for a while.

Introduced a new error code : dstBuffer_null,
I couldn't express anything even remotely similar with existing error codes set.

7b74405150 refactor HUF_compress_internal for clarity 
changed workspace parameter convention
to always provide workspaceSize,
so that size can be explicitly checked.

Also, use more enum to make the meaning of some parameters more explicit.

2b4914082e created zstd_decompress_block module 
isolate all logic associated with block decompression
into its own module.

zstd_decompress is still in charge
of context creation/destruction,
frames, headers, streaming, special blocks, etc.

Compressed blocks themselves are now handled within zstd_decompress_block .

806a5c84e4 support decompressing an empty frame into NULL 
fix #1385
decompressing into NULL was an automatic error.
It is now allowed, as long as the content of the frame is empty.

Seems to simplify things for `arrow`.
Maybe some other projects rely on this behavior ?

1ae38772df restored cmake build tests in Travis 
for some reason, these tests were no longer played on Travis.

As a consequence, I discovered some left-over from the util.c change while testing.

c7942caff0 Clarify special case of offset history update 
If the current sequence has literal length of zero then an offset value
of three is handled in a special manner. While I implemented a golang
decoder I had to consult the educational decoder for clarification on
the update of the offset history in that case. This commit provides the
clarification that the offset value Repeated_Offset1-1 is handled as a
new offset is added to the offset history accordingly.

f181799082 fix decodecorpus incorrect frame generation 
fix #1379
decodecorpus was generating one extraneous byte when `nbSeq==0`.
This is disallowed by the specification.

The reference decoder was just skipping the extraneous byte.
It is now stricter, and flag such situation as an error.
