Trailing white spaces will be now always highlighted, not just in
prog-mode.
Also, the White Space package, which is available since GNU Emacs 22,
is loaded and activated locally in prog-mode.
Additionally, using White Space variables, we set highlighting through
faces on wrong indentation and the maximum length of a coding line.
Notice that:
- The highlighting for the characters beyond the set length of a
coding line is not activated by default, only for wrong
indentations.
- If the White Space package is not available, errors on loading or
activation are ignored.
- If the White Space mode is not activated the set variables would
not have any effect.
v2: Removed too long lines trail highlighting, as suggested by Ilia
Mirkin.

While this is the default, private .emacs files might have it set to
something else. No harm in forcing it to 0.

This limits the style changes to modes inherited from prog-mode. The
main reason to do this is to avoid setting fill-column for people
using Emacs to edit commit messages because 78 characters is too many
to make it wrap properly in git log. Note that makefile-mode also
inherits from prog-mode so the fill column should continue to apply
there.
v2: Apply to all the .dir-locals.el files, not just the one in the
root directory.

Makefiles need hard tabs, let's not make that harder than it needs to be.
