Silence a warning.

Some newer compilers kept warning about an out-of-bounds array access
in Point<1>::operator() but didn't indicate where exactly it came
from. This turned out to be in DataOutBase::write_eps(), a function
that is implemented only for dim==2 but was compiled also for dim==1
and dim==3 and contained this statement: 'points[vertex](1)'. The patch
reorganizes the code so that the function is only compiled for dim==2
and a more general specialization that does nothing but abort is used
for all other dimensions.

Rename output of tests that need PETSc, not Trilinos.
Merge pull request #99 from bangerth/fix-test-signature

Rename output of tests that need PETSc, not Trilinos. The tests actually use PETSc, but their output names suggested that they need Trilinos. This was wrong.
Silence a warning from gcc 4.9.1.

The warning pertained to the fact that we define a function in an anonymous
namespace that is only called from a function inside an #ifdef ... #endif
block. The solution is to move the function into #ifdef ... #endif as well.

This addresses this test result: http://cdash.kyomu.43-1.org/viewBuildError.php?type=1&buildid=11683
Fix a warning about undefined behavior.

I get an error of the form
  /u/bangerth/p/deal.II/1/dealii/include/deal.II/meshworker/dof_info.h:69:9: runtime error: load of value 216, which is not a valid value for type 'bool'
when running the testsuite with the ASAN framework. This is caused by the DoFInfo
class having a member variable that is left uninitialized in the constructor.
Fix this.
