[Bugfix] CLI row hash flags set the wrong values
`--[no-]row-match-finder` do the opposite of what they are supposed to.
In effect the no option would activate row hash while the other option will disable it.
This commit fixes the issue and changes the code to use the more readable enum values.
`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- Added an `assert()`, which controls that `--rm` is no longer active with `stdout`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
```
for f in $(find . \( -path ./.git -o -path ./tests/fuzz/corpora \) -prune -o -type f);
do
sed -i 's/Facebook, Inc\./Meta Platforms, Inc. and affiliates./' $f;
done
```
We've been unable to effectively test cases where stdin/stdout/stderr
are consoles, because in our test cases they generally aren't. Allow the
command line flags `--fake-std{in,out,err}-is-console` to tell the CLI
to pretend that std{in,out,err} is a console.

Adds documentation to help and man pages for legacy pass-through behavior
when force is set and destination is stdout. Documents --pass-through in
man pages
Fixes#3211.
Adds the `--[no-]pass-through` flag which enables/disables pass-through mode.
* `zstdcat`, `zcat`, and `gzcat` default to `--pass-through`.
Pass-through mode can be disabled by passing `--no-pass-through`.
* All other binaries default to not setting pass-through mode.
However, we preserve the legacy behavior of enabling pass-through
mode when writing to stdout with `-f` set, unless pass-through
mode is explicitly disabled with `--no-pass-through`.
Adds a new test for this behavior that should codify the behavior we want.
fileio_types.h cannot be parsed by itself
because it relies on basic types defined in `lib/common/mem.h`.
As for #3231, it likely wasn't detected because `mem.h` was probably included before within target files.
But this is not proper.
A "easy" solution would be to add the missing include,
but each dependency should be considered "bad" by default,
and only allowed if it brings some tangible value.
In this case, since these types are only used to declare internal structure variables
which are effectively only flags,
I believe it's really not valuable to add a dependency on `mem.h` for this purpose
while the standard `int` type can do the same job.
I was expecting some compiler warnings following this change,
but it turns out we don't use `-Wconversion` by default on `zstd` source code,
so there is none.
Nevertheless, I enabled `-Wconversion` locally and proceeded to fix a few conversion warnings in the process.
Adding `-Wconversion` to the list of flags used for `zstd` is something I would be favorable over the long term,
but it cannot be done overnight,
because the nb of places where this warning is triggered is daunting.
Better progressively reduce the nb of triggered `-Wconversion` warnings before enabling this flag by default.
When user pass in argument for both decompression and multi-thread, print a warning message
to indicate that multi-threaded decompression is not supported.
* Add warning when multi-thread decompression is requested
* add test case for multi-threaded decoding warning
Expectation is for -d -T0 we will not throw any warning,
and see warning for any other -d -T(>1) inputs
Adopt the more standard Usage: formatting style
List short and long options alongside where available

Set removeSrcFile back to false when -c or --stdout is used to improve
compatibility with gzip(1) behavior.
gzip(1) is removing the original file on compression unless --stdout or
/-c is used. zstd is defaulting to keep the file unless --rm is used or
when it is called via a gzip symlink, in which it is removing by
default. Specifying -c/--stdout turns this behavior off.
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.
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`.
-r on empty directory resulted in zstd waiting input from stdin. now zstd exits without error and prints a warning message explaining why no processing happened (no files or directories to process).
* 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).
