[core] _WIN32 socket-compat, filesystem-compat

_WIN32 is sufficiently different -- *different*; not better -- that
isolating _WIN32 code is clearer than #ifdef _WIN32 in almost every
func in fdevent.c

_WIN32-specific fdevent_socket_* funcs
  _WIN32 SOCKET fds must be closed with closesocket(), not close()
_WIN32 HANDLE_FLAG_INHERIT for FD_CLOEXEC
_WIN32 use _sopen_s() without _O_TEMPORARY
  Use _sopen_s() without _O_TEMPORARY in fdevent_mkostemp().
  _O_TEMPORARY would remove file once last handle to file is closed.
  Temporary files in chunkqueue may be closed for large request/response
_WIN32 fdevent_rename() using MoveFileExA
  _WIN32 rename() fails if the target file already exists.
  Alternatives are MoveFileExA() or ReplaceFileA().
  Both of the above fail if either oldfile or newfile are open, so
  - not atomic
  - may fail sporadically
