Otherwise, the tests will just fail to compile because of missing headers

to FieldVector::size() as a method.

With this patch applied FieldVector::size remains an enum, hence all your
code compiles as before.  However you get a compiler warning explaining
the issue and suggesting to configure with --enable-fieldvector-size-is-method.
If you do so, then FieldVector::size becomes a method, and you may have
to go out and adjust your code.  The configure flag is transitional and
will be removed after dune 2.2 is out.

Remember that there is no smoother way to do the transition, as you can't
have FieldVector::size to be both an enum value and a method at the same
time.

This fixes FlySpray issue 819.

This is especially useful when an array is needed to initialize a class
member.

This uses a statement like

  array<T, 2> result = { t0, t1 };

to initialize the array.  This is correct and explicitly allowed by the
upcoming standard.  Unfortunately g++ warns about this with -Wmissing-braces
(which is implied by -Wall) because this relies on brace elision.  The report
<http://gcc.gnu.org/bugzilla/show_bug.cgi?id=25137> has been filed more than
five years ago, but so far not much has happened.
