* Allow zero sized buffers in `stream_decompress`. Ensure that we never have two
zero sized buffers in a row so we guarantee forwards progress.
* Make case 4 in `stream_round_trip` do a zero sized buffers call followed by
a full call to guarantee forwards progress.
* Fix `limitCopy()` in legacy decoders.
* Fix memcpy in `zstdmt_compress.c`.
Catches the bug fixed in PR #1939
The `numFiles` variable wasn't updated, so the fuzzer didn't do anything.
I did two things to fix this:
1. Remove the `numFiles` variable entirely.
2. Error if we can't open a file and print the number of files tested.
Cygwin currently uses the fallback implementation which just returns 1 every time,
which leads to bad performance when zstd is called with -T0 for example.
Instead use the POSIX implementation used for the BSDs which works just fine under Cygwin.
Tested under Cygwin and MSYS2.

- only compiles zstd CLI
- enforces zero warning tolerance policy
note : mingw compilation of the library complains (warning) about -fPIC flag.
It mostly ignores it, so it's not a big issue.
Still, it would need to be fixed if library cross-compilation becomes part of CI.
At this stage, it's unclear if this is a scenario.
