the purpose of --ultra is to make the user explicitly opt-in
to generate very large window size (> 8 MB).
The agreement to generate very large window size is already implicit
when selecting --long or --patch-from.
Consequently, `--ultra ` is automatically enabled when `--long` or `--patch-from` is set.
Some older Android libc implementations don't support `fseeko` or `ftello`.
This commit adds a new compile-time macro `LIBC_NO_FSEEKO` as well as a usage in CMake for old Android APIs.
Do some include shuffling for `**.h` files within lib, programs, tests, and zlibWrapper.
`lib/legacy` and `lib/deprecated` are untouched.
`#include`s within `extern "C"` blocks in .cpp files are untouched.
todo: shuffling for `xxhash.h`
* Change CLI to employ multithreading by default
* Document changes to benchmarking, print number of threads for display level >= 4, and add lower bound of 1 for the default number of threads

fix#4186.
Note: there is currently no QNX compilation test in CI
so this is a "blind" fix,
and this target can be silently broken again in the future.
update the man page in troff format,
and the README with latest `--help` content and complementary details about benchmark mode.
also: display level 0 when doing decompression benchmark
After a regrettable update,
the benchmark module ended up reloading sources for every compression level.
While the delay itself is likely torelable,
the main issue is that the `--quiet` mode now also displays a loading summary between each compression line.
This wasn't the original intention, which is to produce a compact view of all compressions.
This is fixed in this version,
where sources are loaded only once, for all compression levels,
and loading summary is only displayed once.
The -Werror=missing-profile caused thread/zlib/lzma/lz4 detection failure
when build with profile-use, thus caused ZSTD_MULTITHREAD etc. is not
defined for profile-use, then there will be many profile mismatch information
in output and the final binary reports run error sometimes as below:
Error : ZSTD_CCtx_setParameter(ctx, ZSTD_c_nbWorkers, adv->nbWorkers) failed : Unsupported parameter

Using '--single-thread' with '--patch-from' on compression levels above 15 will lead to significantly worse compression ratios.
Corrected the man page not suggest anymore to do this.
- switched the patter and input of $filter into the right places
- added pattern wildcard to MSYS_NT & CYGWIN_NT as they change with windows versions
- correctly identify MSYS2, even in an env like MINGW64
