Rewrite the documentation of DoFTools::compute_intergrid_constraints().

CMake: robust version extraction for P4Est

Make the version extraction in P4Est more robust: We should not rely on
the version string to define SUBMINOR and PATCH - this doesn't have to

P4EST_VERSION_PATCH to "0" in FindP4EST.cmake if no valid number could
be extracted.
