[development] let's cleanup /misc

[Khalid B]

You should speak up, and not "keep your mouth shut". A dumb question
is the one never asked, as they say.

I agree it should NOT be in 4.7.  It is too late for major changes for
a release that already has 2 betas out.

For 4.8, I think this should be considered.

Whatever scheme we chose should address

a) Clutter in  the DocumentRoot

b) Security: easier to set file and directory permissions en masse.

c) Isolation (this is the big one  for me) the separation of :

 1. Drupal Core files.
 2. Contributed modules
 3. Site data files (attachments, images, ...etc.).
