This IMO removes a source of error, reduces some lines of code
and only does harm in the case of an accidental return of 77 (which
I do not think will happen)

Feature/cleanup std utility

This merge request cleans up the implementation of C++14 integer
sequences and also removes an old alias of `std::declval()` in our
`Dune::Std` namespace.

Warning: After merging this merge request, any use of `Std::declval()`
will cause compilation failures.

See merge request !82

Add `DUNE_NO_DEPRECATED_BEGIN` and `DUNE_NO_DEPRECATED_END` macros

These macros can be used to mark a block in which deprecation warnings
are ignored.  This can be useful for implementations of deprecated
methods that call other deprecated methods or for testing deprecated
methods in the testsuite.

Improve library handling in dune_enable_all_packages

- Mangle module name (to be c++ conform) when writing library stub
- Support absolute paths when adding files to a library

See merge request !96

These macros can be used to mark a block in which deprecation warnings
are ignored.  This can be useful for implementations of deprecated
methods that call other deprecated methods or for testing deprecated

(cherry picked from commit 6fcb9f2e)

Correctly initialize all members in default constructor.

Allow modules to customize cmake package configuration files

Allows modules to add customized sections to the cmake package configuration files and sets a variable indicating whether this module is installed or not.

 * Mangle module name when configuring stub

[Bugfix][cmake] Fix typo in dune_enable_all_packages()

This typo breaks the module library feature.

See merge request !95

This typo breaks the module library feature - dune-common doesn't even
build for me anymore...

If the module sets the variable @${ProjectName}_INIT then the contents
will be added to the package configuration files.

Variable ProjectName_INSTALLED can be used to query whether this
is an installed module or not.
E.g. this is necessary to adapt include paths for dune-uggrid.

Support multiple DUNE libs in different directories when exporting.

Previously, issuing multiple dune_add_library calls would only
work if subsequent calls to dune_add_library were issued in the same
directory or below. If the calls happened in different directories
then only the last library would have beem exported.
With this commit we can use the APPEND parameter to prevent
overwriting previous libraries.

If all calls are in the same directory or below, then APPEND can be
omitted. But that is not recommend.

Deprecatee final.hh, noexcept.hh and constexpr.hh

The compatibility headers `final.hh`, `noexcept.hh` and `constexpr.hh` are useless since we fully support C++11 so we can deprecate them.

[CMake] Add a helper function to extract paths

Developing CMake code yourself you often need to access
path variables like: What is the build directory of dune-grid?
What is the cmake modules directory of dune-common?
Unfortunately, there are two problems with that:
* The extract method changes depending on whether you are currently
  configuring the module itself or whether you are configuring a
  downstream module.
* Normal people tend to forget the naming schemes of the path variable.

This commit introduces a function with a documented interface that
allows for querying dune module paths. You give it the name of the
dune module, the name of the return variable and a path type.
Currently implemented path types are CMAKE_MODULES and BUILD_DIR.
More may be added as needed.

dune_common_script_dir is a special case that can now be covered by the
more general implementation in dune_module_path.

No longer use deprecated MPI functions

MPI_LB and MPI_UB are deprecated in MPI-2 and have been removed in MPI-3.

This addresses the following warnings (from OpenMPI):

    .../dune/common/parallel/test/remoteindicestest.cc:678:50: warning:
    ‘int MPI_Errhandler_create([...])’ is deprecated: MPI_Errhandler_create
    is superseded by MPI_Comm_create_errhandler in MPI-2.0

[cmake] fixes passing COMPILE_OPTIONS to enable_all_packages

See #30 for description

See merge request !85

This is a variant of stackobject_to_shared_ptr that
can store L- and R-value references. If you pass
an R-value reference it behaves like stackobject_to_shared_ptr.
If you pass an L-value reference it will be moved
into a new object created via make_shared.

The main application of this is the following situation:
If you have a function

  template<class T>
  auto foo(T&& t);

it can be used with temporaries and L-values. If however,
this should return an object referring to t, you can no longer
pass a temporary unless you prolong its life-time. The latter
can be done conveniently using wrap_or_move().

std::index_sequence_for has been made for this very situation...

Most of the time we can rely on std::integer_sequence et. al. being
available, as GCC 4.9+ runs in C++14 mode, so the new version tries to
import the functionality from the standard library.

If it is not available, we now use a fully compliant
implementation (i.e. index_sequence is now an alias template of
integer_sequence, and the various construction helpers are now also
alias templates instead of functions).
