checks that ZSTD_NBTHREADS triggers the expected verbose message
Also: checked that the new test script fails on current `dev` branch, and is fixed by this branch
so that a human reading the test log can determine everything was fine without consulting the shell error code.
Also: made `make check` slightly shorter by moving one longer test to `make test`
replaced `\+` by `*`.
`\+` means `[1-N]`,
while `*` means `[0-N]`,
so it's not strictly equivalent
but `\+` happens to be badly supported on some flavors of grep,
and for the purpose of these tests, `*` is good enough.
such scenario can happen, for example,
when trying a decompression-only benchmark on invalid data.
Other possibilities include an allocation error in an intermediate step.
So far, the benchmark would return immediately, but still return 0.
On command line, this would be confusing, as the program appears successful (though it does not display any successful message).
Now it returns !0, which can be interpreted as an error by command line.
`zstd` CLI has progressively moved to the policy of
ignoring `--rm` command when the output is `stdout`.
The primary drive is to feature a behavior more consistent with `gzip`,
when `--rm` is the default, but is also ignored when output is `stdout`.
Other policies are certainly possible, but would break from this `gzip` convention.
The new policy was inconsistenly enforced, depending on the exact list of commands.
For example, it was possible to circumvent it by using `-c --rm` in this order,
which would re-establish source removal.
- Update the CLI so that it necessarily catch these situations and ensure that `--rm` is always disabled when output is `stdout`.
- Added a warning message in this case (for verbosity 3 `-v`).
- Added an `assert()`, which controls that `--rm` is no longer active with `stdout`
- Added tests, which control the behavior, even when `--rm` is added after `-c`
- Removed some legacy code which where trying to apply a specific policy for the `stdout` + `--rm` case, which is no longer possible

* fix the assertion in readLinesFromFile
When the file is not terminated by endline, readLineFromFile will append
a '\0' for the last line. In this case pos + lineLength == dstCapacity.
* test: don't print very long text garbage
* playtests.sh: fix for a bug in macos' /bin/sh that persists temporary env vars when introduced before function calls
* cli-tests/run.py: Do not use existing ZSTD* envvars
Knowing the version of zlib/lz4/lzma we're linking against is very
useful for debugging issues with those libraries, so print it out in the
verbosity 4 version output.
Also print this information at the top of `playTests.sh`.
* Async IO decompression:
- Added --[no-]asyncio flag for CLI decompression.
- Replaced dstBuffer in decompression with a pool of write jobs.
- Added an ability to execute write jobs in a separate thread.
- Added an ability to wait (join) on all jobs in a thread pool (queued and running).
