0e2dbac18a changed overflow correction place 
keep one in compress_frameChunk(),
so that it's tested at every loop
in case some user simply some large mulit-GB input in a single invocation.

Add one in ZSTD_compressBlock(),
since compressBlock() explicitly skips frameChunk().

f98c69d77c fix : huge (>4GB) stream of blocks 
experimental function ZSTD_compressBlock() is designed for very small data in mind,
for situation where saving the ~12 bytes of frame header can actually make a difference.

Some systems though may have to deal with small and large data entangled.
If it's larger than a block (> 128KB), compressBlock() cannot compress them in one round.

That's why it's possible to compress in multiple rounds.
This is a chain of compressed blocks.

Some users push this capability to the limit, encoding gigantic chain of blocks.
On crossing the 4GB limit, some internal overflow occurs.

This fix moves the overflow correction mechanism higher in the call chain,
so that it's applied also to gigantic chains of blocks.

Added a test case in fuzzer.c, which crashes before the fix, and pass now.

3ff6040848 Publish artifacts with CircleCI 
* Updates CircleCI to use workflows.
  We can now specify any number of test jobs to run in parallel.
* Switch the image to `buildpack-deps:trusty` which is only 500 MB
  instead of 7 GB, so that saves 7 minutes to download it if it isn't
  already cached on the host.
* Publish the source tarball and sha256sum as artifacts.
* If the `GITHUB_TOKEN` environment variable is set, we will also
  add the tarball + sha256sum to the tagged release, after manual
  approval.

63abaf2171 fixed ! tests 
Sometimes, it's necessary to test that a certain command fail, as expected.
Such failure is actually a success, and must not stop the flow of tests.

Several tests were prefixed with `!` to invert return code.
This does not work : it effectively makes the tests pass no matter what.

Use instead function die(), which is meant to trap successes, and transform them into errors.
