Merge sync to keep track with the trunk.

Thanks for renaming files and targets. Always a pleasure to mimic this manually.

At least since version 3.0 CLang support __cxa_demangle. To support as
many compilers as possible we test for the feature instead of testing
for the compiler version.

Thanks to Andreas Lauser <and@poware.org> for providing this patch
(see FS #1246)

(calms down clang warning)

[[Imported from SVN: r7113]]

n dune/common/share_ptr.hh the constructor of SharedCount is defined to be a template. However, the template argument is never used. This template argument was now dropped.

Patch kindly provided by Olaf Ippisch

Move template specializations of matrix capabilities into header. Restrict call to methods solve(), invert() to invertible matrices.

BTW: Currently they are not at all activated in dune-common.

Fixed function call in test code, because indexSet_ is a pointer. Clang complained.

Add support for boost::hash

This patch adds boost::hash as a fallback option for Dune::hash
if neither std::hash nor std::tr1::hash can be found. We only
have to include the appropriate header and import the name into
the Dune namespace, as the built-in extension mechanism of boost::hash
will automatically pick up the global hash_value() functions.

To test whether the mechanism actually works, the patch also adds
boost::hash to the list of hash implementations tested in
bigunsignedinttest.

Kudos to Steffen Müthing, see FS#1192

Make bigunsignedint hashable using Dune::hash

This patch adds the required hooks to enable hashing of bigunsignedint
and makes sure the hasher can be invoked in bigunsignedinttest.

Making bigunsignedint hashable also makes it possible to use hash-based
containers for EntityIDs with YaspGrid and SGrid, as those grids implement
the EntityID as a plain bigunsignedint.

The patch also adds a little test to bigunsignedinttest, trying to hash
a bigunsignedint with Dune::hash as well as any of the detected backends
(std::hash and std::tr1::hash).

Kudos to Steffen Müthing, see FS#1192

Add basic support for hashing using Dune::hash

This patch introduces the functor Dune::hash in a similar manner to
other C++11 functionality by importing the definition from namespace std.

Apart from that, the patch also provides some basic functionality to simplify
making user-defined types hashable, in particular functions for combining hashes
and hashing iterator ranges as well as a mechanism for defining the struct
specializations required by std::hash and std::tr1::hash in the correct namespace.

The current implementation will first try to use std::hash and, if that fails,
attempt to fall back on std::tr1::hash. If that is not available either, hash
support is disabled as there is no homegrown fallback for now.
The extension mechanism will register the type with both std::hash and std::tr1::hash,
if available. This should make it possible to use unordered_{set,map} from both C++11
and TR1 without having to specify a custom hasher.

Kudos to Steffen Müthing, see FS#1192

Remove cast operator that caused Clang warnings.
This fixes FS#1207.

Kudos to Ansgar Burchardt for the patch.
