With this patch autotools now creates the file
<dune-module>-config-version.cmake mit autotools. To facilitate this
we added the variables DUNE_MOD_{MAJOR,MINOR,REVISION} to the makefiles.

With this patch dunecontrol will work even if the path to the module
contains spaces. Unfortunately, the tests for dune modules will still
not work as I could not figure out how to use quoting in the CPP_FLAGS.

Some modules do test for complicated symbols,
eg. "&StandardMerge<double,1,1,1>::build;", which lead to broken
configure scripts. In the above case :
" 1>build;
  ;"
as a shell command.
This patch quotes the program body used for AC_LANG_PROGRAM correctly
to prevent this.

make sure that flags passed with DUNE_LDFLAGS are the first flags in linker test and not duplicated another time.

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

libs to the ALL_PKG_* family of variables and DUNE_ADD_MODULE_DEPS to add
flags and libs to the DUNE_* family of variables and the modules variables.
Use those macros in DUNE_CHECK_MODULES.

 * Essentially copy and adapt the definition of AC_CHECK_LIB.  This should
   make sure the two macros behave the same even in corner cases (except for
   the added functionality, of course).

 * Properly document what exactly is allowed in the arguments.

Parse arguments to DUNE_CHECK_LIBS_EXT properly in parmetis.  This avoids
expansions like 'LDFLAGS="$LDFLAGS -L"$PARMETISLIBPATH""'.

support for out-of-source builds in Dune.

You call dunecontrol with a parameter --builddir=NAME
dunecontrol will create a subdirectory NAME inside each 
module and do an out-of-source build there.

Not necessarily all modules support out-of-source, but at 
least common/istl did work.
