"Makefile.in", "*.o", etc. need only be listed in the toplevel .gitignore, the
rules are applied recursively.

Test programs etc. should be listed as "/program" in their directory's
.gitignore, so they are not accidentially ignored in a lower level directory.

assert() works only in debug builds (without -DNDEBUG).  Instead, implement
our own check_assert().

Rip out the complete test for eigenValuesNonSym and replace it by the Rosser matrix test from fieldmatrixtest.cc

The old test was complete nonsense: an implementation of some sort of strange
undocumented shape function set that happened to need eigenvalues for something.
Lots of undocumented code, and no checks at all whether the values obtained
by eigenValuesNonSym actually make sense.

Only, for the particular choice of parameters used, eigenValuesNonSym was never
called.  Yes, you read this correctly: these hundreds of lines of code didn't
actually test anything.

The new test is copied form fieldmatrixtest.cc and adapted for DynamicMatrix
types.  It computes eigenvalues of a given 8x8 matrix and compares with the known
results.  Unfortunately, the test matrix is only symmetric.  Tests with more
general matrices are left for another day.

These classes are deprecated, and some of the tests cause
problems with ctest due to a destructor throwing an exception.
It seems easier to remove the tests directly, as the tested code
is deprecated anyway.

testdebugallocator_fail{1..5} are a very special sort of tests,
as in order to pass they are expected to fail with a signal like
SIGABRT or SIGSEGV. While autotools, dont distinguish much
about how a test failed, if it is supposed to fail, ctest
handles signals from the test and distinguishes this from
normal termination with nonzero exit code.

This commit introduces a signal handling in the test itself,
that causes the program to terminate "normally" with a nonzero exit
code instead of passing the signal to the fathering process
(ctest). The signal, which is expected to be received can be set
from CMakeLists.txt via a preprocessor variable.

C++14 will introduce integer/index sequences in the header <utility>.
This patch introduces a backwards compatible implementation similar in
use. However, the implementation differs in the following technical
details:

  - index_sequence is not a template alias for integer_sequence but
  inherits from it

  - make_{integer, index}_sequence are not a template aliases but free
  standing functions

Both differences stem from the absence of template aliases introduced in
GCC aa late as gcc-4.7. This implementation will work in gcc-4.4 and
later.

nullptr-test.cc: Move semicolon to own line to prevent
Clang warning.
typetraitstest.cc: Exclude use of deprecated types
PointeeType and ReferredType with
DISABLE_DEPRECATED_METHOD_CHECKS defined.

Test (almost) all methods requested by the STL
(as documented on http://www.cplusplus.com/reference/iterator/ForwardIterator/ )

Test whether std::iterator_traits is properly specialized.

This avoids compiler warning about implicitly rounded to zero

This reverts commit cf4bf4d8.

The epxlicit cast isn't needed anymore as we have a fix for the
ambiguous operator overload.

The bug affected operators: +=, -=, *=, /=. It has been fixed by using:
enable_if<is_convertible<ParamType, FieldVector::valueType>, ...>

oelements stores longs which need to be converted to pointers before freeing.
Previously we actually free the entries of the array oelements and not the
stored pointers.

(the problem are operators of the type FieldVector<double,1> *= int)
clang fails and gcc (4.7) warns about
ISO C++ saying that these operators are aambiguous

When copying PoolAllocators Bard experienced linking errors to the
copy constructor of Pool, which is deactivated. To fix this we added
the copy constructor. Note that it does not copy the pool such that
ownership of allocated memory chunks is clear.

Kudos go to Bard for noticing this and providing the fix.

In addition we removed the copy constructor of the specialization for
void as the default coy constructor suffices.

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.

This patch introduces a new macro DUNE_UNUSED_PARAMETER(parm) for marking
unused parameters that are there for a purpose (e.g. the prescribed interfac
The macro simply performs a cast to void. In addition all unused parameter w
that I found were removed.

At least Clang 3.2 complains.

These are replacements for TypeTraits::isPointer, TypeTraits::isReference,
TypeTraits::PointeeType.  They reimplement what is available in the
C++11 standard library, and are expected to supersede the TypeTraits
class eventually.

Note: this patch does not pull in the corresponding stl implementation.
