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.

6c51bf420c bounds for --adapt mode

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.

06fd1e473d 'head -c BYTES' is non-portable.
tests/playTests.sh uses 'head -c' in a couple of tests to truncate the
last byte of a file. The '-c' option is non-portable (not in POSIX).
Instead use a wrapper around dd (truncateLastByte).

0ff9b67552 paramgrill: removed useless tests
designed to compensate iter_mode,
but since only time_mode is available now,
all tests are guaranteed to last a minimum amount of time.

9e26893e07 paramgrill: fixed a bunch of div-by-zero
they were pretty easy to trigger by the way,
just start an extended paramgrill session
to find a compression table based on any sample,
it would necessarily happen at some point.

0071e8348f restored assert() in paramgrill
assert() in paramgrill are not in the benchmark path.
They should remain active, as they don't impact measurements, and their runtime is insignificant.

* Add FASTCOVER_MEMMULT

* Minor fix

* Update benchmarking result

Merge pull request #1290 from edenzik/ezik/1119-safe-strcpy-in-fileio
Fixed unsafe string copy and concat in `fileio.c`.

78af534f82 Fixed unsafe string copy and concat in fileio.c.
Per warnings from flawfinder: "Does not check for buffer overflows when
copying to destination [MS-banned] (CWE-120). Consider using snprintf,
strcpy_s, or strlcpy (warning: strncpy easily misused).".

Replaced called to strcpy and strcat in `fileio.c` to calls with a
specified size (`strncpy` and `strncat`).

Tested the changes on OSX, Linux, Windows.
On OSX + Linux, changes were tested with ASAN. The following flags were
used: 'check_initialization_order=1:strict_init_order=1:detect_odr_violation=1:detect_stack_use_after_return=1'

To reproduce warning:
./flawfinder.py ./programs/fileio.c
