Macro to use C++11 feature noexcept specifier.
Add test for CMake and autotools.

There is more macro magic to be removed.

With GCC 4.4 or newer HAVE_INTEGRL_CONSTANT, HAVE_STD_HASH, and
HAVE_TYPE_TRAITS is always 1, no further testing necessary.
The test defines will be removed after the next Dune release.

This was used for backwards compatibility only.

As we have bumped our compiler requirements to GCC 4.4+, we can now
require the compiler to support C++11.

This patch updates both the autotools and the CMake tests to produce an
error if the compiler doesn't support either -std=c++11 or -std=c++0x.

It also renames the tests from ..0X to ..11 and renames the configure
options from --disable-gxx0xcheck to --disable-cxx11check and removes a
couple of redundant calls to the autotools macro.

dune_deprecated_cppflags.m4 was removed in 2a4965d9
CheckSharedPtr.cmake was removed in 7205583c

Its call was removed from dune_mpi.m4 back in 2012.

Deprecate header and macro dune_static_assert.
Use static_assert instead.

They cased compiler warnings.

This patch adds an AutoTools test that tests whether the compiler
supports the 'final' keyword.  It defines the DUNE_FINAL preprocessor
macro, which expands to 'final' if the keyword is supported, and
is empty otherwise.

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.

Improve comments.

Previously, the macros were installed to $(datadir)/aclocal. As we have
some macros in DUNE that are also installed for some Linux distributions
this caused conflicts in package managers. With this patch we install
them to $(datadir)/dune/aclocal to resolve this issue outlined in flyspray

This fixes FS#1404.

As decided in the doodle for FS#1395, really old MPI versions will be
deprecated in the 2.3 release.

This patch adds an additional check to the MPI tests for autotools and
cmake that makes sure the user has an MPI which is at least compliant
with MPI-2.1. If the user's version is older, a warning is generated.

The test uses version macros instead of the more standard runtime
MPI version query interface to avoid problems when cross-compiling.

The check for constexpr was not copied into the distribution.
Unfortunately, the autotools will only warn about a missing macro, but
give valid results otherwise. This patch adds the cxx11_constexpr.m4 to
Makefile.am, so that it is distributed on "make dist".

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.
