cf5e5b5711Notable changes: - win,tcp: make `uv_close()` work more like unix. - 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. - fix a bug that would cause libuv to hang if the user called `uv_shutdown()`. - darwin: fix `uv_barrier()` race condition.
