Adopt the more standard Usage: formatting style
List short and long options alongside where available
Print lists as a table
Use command style description
Newer less versions appear to have changed how stderr
and stdout are showing error messages. hardcode the
expected behavior to make the tests pass with any less version.
Also set locale to C so that the strings are matching.
- As referenced by Nick Terrelln ~ the ZSTD maintainer in the linux kernel, making zstd_reset_cstream() functionally identical to ZSTD_resetCStream() would be the perfect way to fix the warning without touching any core functions or breaking other parts of the code.

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 previous patch throws the following warning:
../linux/lib/zstd/zstd_compress_module.c: In function ‘zstd_reset_cstream’:

cc1: all warnings being treated as errors
Since we have a choice to either use ZSTD_CCtx_reset or ZSTD_CCtx_setPledgedSrcSize instead of ZSTD_resetCStream, let's switch to ZSTD_CCtx_setPledgedSrcSize to not have any unnecessary warns alongside the kernel build and CI test build.

- This fixes the below warning:
../lib/zstd/zstd_compress_module.c: In function 'zstd_reset_cstream':
../lib/zstd/zstd_compress_module.c:136:9: warning: 'ZSTD_resetCStream' is deprecated [-Wdeprecated-declarations]
136 | return ZSTD_resetCStream(cstream, pledged_src_size);

2277 | size_t ZSTD_resetCStream(ZSTD_CStream* zcs, unsigned long long pledgedSrcSize);
| ^~~~~~~~~~~~~~~~~
ZSTD_resetCstream is deprecated and zstd_CCtx_reset is suggested to use hence let's switch to it.

* 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
We already have BIT_getLowerBits, so use it. Benefits are 2fold:
1) Somewhat cleaner code
2) We are now using bzhi instructions, when available. Performance
delta is too small for microbenchmarks, but avoiding load still helps
larger applications, by reducing data cache pressure.
