09caa4d800 [fuzzer] Add a fuzzer for frame info functions 
Add a fuzzer that fuzzes all helper functions that take compressed
input. This fuzzer caught one out of bounds read in
`ZSTD_decompressBound()`.

c5d70b7dbb [fuzzer] Sometimes fuzz with one less output byte 
Zstd compression sometimes does different stuff when it has at least
`ZSTD_compressBound()` output bytes, or not. Half of the time fuzz with
`ZSTD_compressBound() - 1` output bytes. Ensure that we have at least
one byte of overhead by disabling either the dictionary ID or checksum.

d8e215cbee created ZSTD_compress2() and ZSTD_compressStream2() 
ZSTD_compress_generic() is renamed ZSTD_compressStream2().

Note that, for the time being,
the "stable" API and advanced one use different parameter planes :
setting parameters using the advanced API does not influence ZSTD_compressStream()
and using ZSTD_initCStream() does not influence parameters for ZSTD_compressStream2().

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.

fa41bcc2c2 grouped debug functions into debug.h 
There were 2 competing set of debug functions
within zstd_internal.h and bitstream.h.
They were mostly duplicate, and required care to avoid messing with each other.

There is now a single implementation, shared by both.

Significant change :
The macro variable ZSTD_DEBUG does no longer exist,
it has been replaced by DEBUGLEVEL,
which required modifying several source files.

0b1833c2cb fixed regressiontest 
ZSTD_TARGETLEN_MIN no longer exists
since is would be tautological to check if an unsigned value is < 0.

471aa385b3 [fuzz] Speed up round trip tests 
* Enforce smaller maximum values for parameters
* Adjust parameters to the source size

The memory usage is reduced by about 5x, which makes the fuzzers run at
least twice as fast, even more so with ASAN/MSAN enabled.
