Remove all references to grids.  These are unknown in dune-geometry.

Remove deprecated function &instance().

Remove call to deprecated GenericType::basicType() in preparation of
removing the deprecated method.

- removes one layer of redirection
- removes one occurrence of the codim-wrt-the grid
  concept, which shouldn't occur in dune-geometry

Unfortunately, that led to code duplication.

 affine and volume tests into their own functions.

This avoids the use of isnan (which is a macro in C99 but a function in
C++11), avoids the use of the somewhat obscure "a == a" test for NaNs, and is
much clearer than using some special volume for the volume anyway.

Thanks to Jö for the patch.

This patch allows the user to store additional data in the mapping.
This user data is assumed to be independent of the topology and, hence, can
be accessed through non-virtual methods (even when HybridMapping is used).

In order to avoid storing the user data twice, the CachedMapping has been split
into a new NonHybridMapping and the CachedMapping itself. The new user-visible
class is NonHybridMapping. This should also clarify the semantics of the methods
trace and clone, which no longer reside on the CachedMapping but on the
NonHybridMapping.

The impact of this patch on the user is relatively low. You will only notice it
in two situations:
a) Your GeometryTraits class (e.g., GlobalGeometryTraits) is not derived from
   DefaultGeometryTraits. In this case you have to add a type UserData (see
   DefaultGeometryTraits for an example).
b) You are using the CachedMapping directly, i.e., you are not using one of
   the classes GenericGeometry::BasicGeometry, GenericGeometry::Geometry, or
   GenericGeometry::LocalGeomtry. In this case you simply replace CachedMapping
   by NonHybridMapping.

* use maxima to compute quadrature rule
* see FS1054
* kudos to Ansgar Burchardt

* avoid obscure return statement
* strangely we have to keep brackets around the statement, otherwise
  m4 creates a strange substitution
