Move darwin_utilities to a directory of its own

[sagetrac-gouezel]

Since #17767, all pyx files in sage/misc are compiled on all platforms, due to the following line in modules_list.py:

Extension('*', ['sage/misc/*.pyx'])

This is in particular the case of sage/misc/darwin_utilities.pyx, which should however only be included on Darwin as specified on lines 2096 and following of modules_list.py:

# Only include darwin_utilities on OS_X >= 10.5

This ticket moves this file and its friends to a subdirectory of its own.

Depends on #18145

NB: the patch is untested as I don't have a Mac...

I would not put this inside misc but perhaps a new top-level directory like src/sage/platform.

If you really go for a src/sage/platforms/darwin/ directory, you can drop the darwin_ prefix on all files.

Good idea, done.

I have no more comments but somebody with OS X (not me, unfortunately) should test this.

I think that #18145 also fixes the issue on this ticket, but in a completely different way.

In any case, this patch will conflict with #18145.

Indeed, #18145 fixes the issue, so this ticket is not needed any more.
