Deprecate header and macro dune_static_assert.
Use static_assert instead.

DUNE_FINAL is a helper macro for C++11 and should be placed in
std, where now all compatibility has to be placed.
Beautify Doxygen documentation.

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.

kudos to Elias Pipping, for details see (FS #1166)
as the new Dune requirements are >= g++ 4.4 we are sure that initializer_list is available.

remove output and replace it with assertions.

Note remove_reference is necessary, because you cannot extract the iterator type from
row_reference directly in case: row_reference == row_type&

IteratorFacades::Pointer is assumed to be T* which is not the case for row_reference != row_type&.

Add additional template parameter R (default T&) to handle the case row_reference != row_type&.

This fixes FS#1398 for dune-common.

Use conditional instead.

These headers were moved in Dune 2.3.

The last patch missed a change in the comparison operators. Allocators
compare as equal if memory allocated with one can be deallocate with
the other. With this allocators compare equal only if they are share
the same address.

Cherry-pick from branch eature/FS1429-shared-lib-fixes where it ended up
by accident.

Due to its desgin of using one static memory pool. The allocator
could not be used in different threads at the same time without
side effects. With this revision each instance will hold its own private
instance of the pool.

There should be no issues with this patch and poolallocator seems to be
mostly used in AMG anyway.

when we try to send data, it might happen, that for some reason we don't want to any data.
This happens, when the dynamic size of our CommPolicy is 0. In that case we must not add a
MessageInformation, otherwise we get an MPI error.

Somehow, the vector version of CollectiveCommunication< MPI_Comm >::prod
passed std::plus to allreduce (instead of std::multiplies). This patch
corrects this flaw.
