As decided on the developer meeting in Aachen, we support (but do not rely on) the C++11 keyword constexpr. This patch adds an m4-check for constexpr and a header (cxx11.hh) defining a macro DUNE_CONSTEXPR either as constexpr or empty (depending on the compiler support for it). It is then used in FieldVector and FieldMatrix on size, rows, and cols.
