This reverts commit 5f053401.

I was a little hasty in cherry-picking this from the dune_enable_all_packages()
branch, as it needs some infrastructure from over there.

Until now, the global properties that hold the collection of flags
for all packages have been updated manually in each find module. It
might be convenient for developers to put this into a macro that
uses CMakeParseArguments.

Exclusion from the headercheck can be achieved in a CMakeLists.txt
file via the following macros:

exclude_from_headercheck(list...)
exclude_dir_from_headercheck()
exclude_all_but_from_headercheck(list...)

When not excluded, all headers matching dune/*.hh or src/*.hh
will be checked.

Unlike with autotools, make headercheck can only be called on the
toplevel module directory and then run on all module headers. In
contrast to autotools, CMake will cache the results and rerun only
checks on changed headers.

Find<Package>.cmake modules, as they were missing with set
CMAKE_DISABLE_<Package>=TRUE.

Now they are in speparte modules Add<Package>Flags and thus can be
used as exspected with disabled packages.

  latter should be used to specify the location of the cmake package
  config file. 
- [BugFix] Set HAVE_PARMETIS for config.h generation
- Use check_function_exists to search for parmetis_v3_partkway.
  The previously used check_symbol_exists is meant for checking
  symbols defined in headers.

The latter is the location of the package configuration files.

without PATH and NO_DEFAULT_PATH.

Removed ifclauses around second search as due to caching the search
will not be performed if the first find was successful.

Renamed add_parmetis_flags to add_dune_parmetis_flags for consistency.
