Passing multiple files to dune_symlink_to_source_files() was broken.
While at it, I switched the given macros to be functions and have
named arguments. Using positional arguments will result in a warning.

ptrdiff_t is a signed integer type and so the expression
  (std::uintptr_t)(ptr) % page_size
could become a negative value. In this case the page_ptr would be the
address of the next page after the allocation.

This wrong behaviour could be observed on (32bit) PowerPC: here
ptr was 0xf78cfe00 and page_ptr was calculated as 0xf78d0000 instead
of the correct 0xf78c0000.

We have to call add_definitions() in a loop because add_definitions() is
kind of broken: even though it is supposed to be *the* function for
adding compile definitions, it does not prepend "-D" (as opposed to
target_compile_definitions(), which does). Well, whatever...

This branch resolves somes smaller problems with the
dune_enable_all_packages() feature and importantly provides support for
modules with libraries and CMake < 3.1.

* feature/FS1654-improve-dune-enable-all-packages:
  [Release][CMake] Add support for compile options in DuneEnableAllPackages
  [Release][CMake][Bugfix] Use correct test in if() command
  [Release][CMake] Add dune_target_enable_all_packages()
  [Release][CMake][Bugfix] Remove stray unset() command
  [Release][CMake] Convert macros to functions in DuneEnableAllPackages
  [Release][CMake] Improve documentation in DuneEnableAllPackages.cmake

We do not really support this combination of C++11 features, and the
only time it should occur is when the user has a recent Intel Compiler
and an outdated GCC (which the Intel Compiler uses for the C++ standard
library). In that case, we emit a helpful error message at configuration
time.

The std::numeric_limits specialization for bigunsignedint requires
access to the internal state of bigunsignedint. Previously, the correct
specialization of std::numeric_limits was a friend of bigunsignedint,
but that creates problems on recent versions of clang with the
alternative libc++ library, because that library declares the base
template of std::numeric_limits as a class and clang subsequently
complains if the friend declaration uses 'struct'. Unfortunately,
libstdc++ uses a struct, making it impossible to keep clang happy for
both standard libraries. So we introduce a helper class that provides
access to the internal state and which now becomes a friend of
bigunsignedint. The numeric_limits specialization inherits from the
helper to use it.

According to the standard, all specializations of std::hash must export
argument_type and result_type [20.8.12/1]. The version of libc++ (LLVM's
alternative C++ standard library) tripped over this requirement on my
machine, so this patch adds the typedefs.

The test for __cxa_demangle(), which is used by Dune::className() to
demangle type names, doesn't work on my clang 3.6. Apparently, clang
requires the user to include <typeinfo> before <cxxabi.h>. While
classname.hh already does this, the build system tests don't, causing the
feature to get disabled on clang.

Fixed by adding the include to the build system tests.

Although GNU find may allow to omit the directory
argument, an ordinary (e.g. BSD) find does not.

DuneEnableAllPackages.cmake, FindThreadsCMake31.cmake and

Before this commit communcation would be initiated even on empty
interfaces. While this does not lead to overwriting data or producing
segmentation faults, it does lead to accessing the first component of
empty vectors to get a pointer to pass to MPI functions. This produces
error output with valgrind and other memory debuggers. Therefore with this
commit we will first check whether the interface contains values and do
nothing if it doesn't. We also augmented the test to catch the case wher only
some processes have an empty interface.

This fixes FS#1614.

The Metis test used the wrong one and I copied it for PTScotch... :/

This test has been added while the dune_enable_all_packages
feature was developed...

This branch adds the required infrastructure to automatically enable all
external packages and Dune-internal libraries for all targets inside a
given Dune modules. For this purpose, it adds a number of new CMake
macros:

- dune_enable_all_packages is the central macro that needs to be called
  in the main CMakeLists.txt of your project.

- dune_library_add_sources is an optional macro that you only need if
  your project also contains a library and you want your executables to
  automatically link against that library. Note that this support
  requires CMake 3.1. Most user modules don't create their own libraries
  and can thus ignore this macro.

- dune_register_package_flags has to be called in all configuration
  tests to register the outcome of the test so that
  dune_enable_all_packages can automatically add the required compiler
  and linker flags required to use the library that the configuration
  test has been written for.

The branch also adds the required calls to dune_register_package_flags
to all configuration tests in dune_common.

There is a similar branch in dune-grid that updates the configuration
tests in that module.
