Paraview fix

Bugfix: netlib-scalapack does not work with all versions of python

RPATH was collecting all lib from all dependencies, when dep tree is deep like in ParaView the path was growing too much, showing install problems  now just direct dependencies rpath is added

- Recent external repo refactoring made `repo_for_pkg` raise an error
  when the package was not known.

- Correct behavior is to return the highest precedence repo.

fix : trilinos and dependencies

hdf5: always pass the unsupported flag

Add latest libgpg-error version

Add latest qhull version

Add Phonopy and PyYAML Python modules

Added package : OpenCV

This flag can end up being required if a dependency tree ends up needing
hdf5+cxx+parallel, but nothing turns it on. Since the core spack code
puts this together, it ends up that the end user needs to specify it
manually. Instead, just assume an unsupported configuration (since these
*are* useful setups) and if anyone wants to seek upstream support,
masking the flag can be done.
