Done.  Available from https://bitbucket.org/mituharu/emacs-mac.git as
usual.

I also created a new branch `experimental/mac-gui-thread' in the above
repository for preparation of multi-thread support in Emacs 26.  The
branch itself is still based on Emacs 25 to test this new design and
code on top of a stable basis.

It runs the Lisp REPL in a non-main thread, so the main thread is
dedicated to GUI tasks, which might be requested from multiple Lisp
threads if we switch to version 26.  The GUI and Lisp threads run
mostly cooperatively (i.e., do not run simultaneously) except in the
`select' emulation.  Note that the variable `main_thread' in sysdep.c
no longer corresponds to the "main thread" in a usual sense.

If you want light scroll bars, title bars, etc. while using a dark
frame background color as it used to be, then customize the
`scroll-bar-background' frame parameter to "white", for example.
