- cleanup,win: Remove `_WIN32` guards on threadpool.
- more errno mappings and fixes.
- higher performance try-writes.
- fix string encoding issue of `uv_os_gethostname()` (note: MINGW-W64
  upstream is broken on i686 due to
  https://sourceforge.net/p/mingw-w64/bugs/899/).
- zOS support.
- Workarounds for a `copy_file_range()` kernel bug.
- Better support for TSan.
- darwin: use `RLIMIT_STACK` for fsevents pthread.
