apply the two caching patches proposed by Christoph Grüninger,
at least for me they worked flawless and showed some considerable configure speedup.

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

* add DUNE_DEPRECATED_MSG("message") macro

Since various compiler versions only support the 'unused'
attribute without a message, one has to check for both
versions separately.  Cf. the discussion in FS 956.

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.
