The first 3 commits fix bugs found by the CLI testing platform and fix

The 4th commit adds the new CLI testing platform that I'm proposing.
See tests/cli-tests/README.md here.

The final commit hooks the CLI test suite into make test, but not
make check. This runs in CI everywhere that make test runs.

Passing 0 inputs to `DiB_shuffle()` caused an assertion failure where
it should just return.

A test is added in a later commit, with the initial introduction of the
new testing framework.

Fixes facebook#3007.
The option `--auto-threads` should still be accepted and parsed, even if
`ZSTD_MULTITHREAD` is not defined. It doesn't mean anything, but we
should still accept the option. Since we want scripts to be able to work
generically.

This bug was caught by tests I added to the new testing framework.
`datagen` was printing a `\n` even when it had no other output. Raise
the output level for the final `\n` to the minimum output level used.

This minor bug was caught by the new testing framework.
Adds the new CLI testing platform that I'm proposing.
See the added `README.md` for details.
Add cli-tests to `make test`. This adds a `python3` dependency to `make
test`, but not `make check`. We could make this dependency optional by
skipping the tests if `python3` is not present.

The only remaining failure is in the static-analysis. It seems unrelated to code that I've modified. However, I only see if failing on this PR, so I will attempt to fix it.

* It couldn't detect that the `fastCoverParams` can't be non-null, since it was just an assertion.
* It thought we were accesing `wksp->dtable` beyond the bounds because we were using it to set the `workSpace` value. Instead, compute the workspace size used in a different way.

The new Travis CI test failure is an infra error unrelated to the PR. And I don't know why the MSAN regression was skipped, but it passed on the previous revision. So I'm tempted to just merge as-is.
