For discussion check FS1648.

Disabling a cmake module through CMAKE_DISABLE_FIND_PACKAGE_...
was only partially working:
- Any module suggesting the disabled module would not search for it
- dunecontrol did not have this knowledge and built the disabled module nevertheless

This commit fixes the latter.

the first problem was that I accidentially enabled the ScalarOrderingTest, but this forced me
to investigate further and I found out how this works, or not works.

We have to add the comparison operators to FieldVector, as the cast operator does not always
match, e.g. in the case of GMPField.

in order to make GMPField work in more situations, we add a constrctor, which matches
all scalar data types, which can me converted to K.
We deliberately exclude K from the template match.

we first import function like std::max into the local scope and the call max(a,b) instead of
std::max(a,b). This allows to match specializations for other data types via ADL.

The templated constructor of GMPField fatched everything. We reduce the constructor
to those scalar values, which are convertible to mpf_class. As this removes the constructor
from char* we explicitly add constructor from char* and std::string.

This is the main part to fix FS#1665

most of the tests work. std::complex<GMPField> does not work as expected, but this is
perhaps something we don't want to support. As std::complex does not allow to initialize
with other parameters than the data type itself, we can not initialize from int or other
compatible scalar values. The smae problem occures when interacting with int values directly.

dune_library_add_sources() verifies the library name against the
contents of DUNE_ENABLE_ALL_PACKAGES_MODULE_LIBRARIES. I accidentally
broke this by converting dune_enable_all_packages (which defines the
variable) from a macro to a function, which removed the variable from
global scope.

This patch fixes the problem by explicitly exporting the variable to the
parent scope, making it available to dune_library_add_sources() again.

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...

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.
