TestParallelRendering was not originally designed to be run as a
test. Fixed. It does not do image comparison but at least runs as
part of the test suite. This class is covered well in the ParaView
testing suite.

Change-Id: Ic579396983698c5448b806ce6082b37a9cd8d4b5

Add optional test macro arguments to allow for some of the tests to
depend on VTK_LARGE_DATA_ROOT and for most of the tests to have
their correct images in an pre-modularized vtkdata directory layout.
NOTE: This requires some VTKDATA file movement because old tests
have names like tname.cxx.png and this assumes tname.png.

Also make TestParallelRendering return some sort of pass/fail result.

Since the transition away from CVS and commit ecbbf7f7 (Remove
vtk(Cxx|Type)RevisionMacro, 2010-05-19) the per-file revisions reported
by vtkObjectBase::(CollectRevisions|PrintRevisions) have not been
implemented.  Drop these methods.  Define associated macros

  vtkExportedTypeRevisionMacro
  vtkTypeRevisionMacro
  vtkCxxRevisionMacro

to have no extra effects and only when VTK_LEGACY_REMOVE is OFF.
When VTK_LEGACY_REMOVE is OFF drop the PrintRevisions special
case from wrapping.

Exclude ThirdParty, Utilities/MetaIO, and Utilities/KWSys as these
are maintained outside VTK.

Move source files from their former monolithic VTK location to their new
location in modular VTK without modification.  This preserves enough
information for "git blame -M" and "git log --follow" to connect
modularized VTK files to their original location and history.
