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

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>.

Note: I looked through the patch and asserted that the resume feature is still
working (I always overwrite the resume file anyway). In case dunecontrol stops
working for someone, please simply revert this patch (if possible) and add a
comment to FS#958).

document how key/value pairs have to appear in the command line options so that readOptions recognizes them

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

Credits to Andreas Lauser.

* add DUNE_DEPRECATED_MSG("message") macro
* credits to Andreas Lauser

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.
