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

Measurements showed no speed increase at all, compared
to retrieving the last element first and then calling
pop_back().  See dune-grid commit message 7837 for
details on the measuring process.

Seems like not many people use this class :-)

Thanks to Elias Pipping for the patch.

Kudos to Christoph Grüninger with two additions:
 * Note that the transition code should be removed before the next release.
 * Don't give people warnings about <dune/common/geometrytype.hh> just because
   they included <dune/common/geometrytypeindex.hh> or
   <dune/geometry/typeindex.hh>.

file format does not belong in the class description, because the class
parses other input sources as well.

HAS_ATTRIBUTE_DEPRECATED_MSG in config.h and move the rest into
dune/common/deprecated.hh. this should fix older autotools and is
conceptionally cleaner IMHO

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.
