Stokhos:  Worked on CUSP multi-RHS AMG solve.

Improved the multi-RHS row-wise layout kernel and got everything working
with column-wise for comparison.  A lot of whitespace fixing.  Improved
the example and added performance drivers for spmm and solve.
Teuchos:  Rolling back Christian's most recent scalar traits change.

The change causes build errors in KokkosClassic.  I think we need to
quite trying to change this file and just get the ArithTraits in to
Kokkos.
Lines within line smoothers can now be determined via coordinates.
In particular, a line is defined as a set of points having the
same x and y coordinates (but generally different z coordinates).
MueLu, Zoltan2: compiler warning fixes
MueLu: EasyParameterInterface: bugfix
Xpetra: fixed instantiation of CrsMatrix tests
MueLu: EasyParameterInterpreter: added missing "repartition: keep proc 0" option
MueLu: repartition: improving invariance to remapping

Remapping may affect aggregation for next level. This patch strives to
mitigate this situation by reducing its effect.
Put new line smoothing options in the parameter validator.
ML: fixing compile error if AztecOO not enabled
Tpetra: writer now supports long long

This is a small change to allow writing matrices w/ GO=long long.
I also made an exception message more to the point.
MueLu: remove disableDirichletDetection option

This was a temporary option.  I have also fixed Dirichlet detection
for systems.  Now, a node is marked as Dirichlet only if all the
associated DOFs are Dirichlet themselves.  Previously, the node would
be marked if any associated DOF was Dirichlet.
Trilinos: fixing cmake typo in nightly test

While the script was working, the syntax for specifying the blas and lapack
library locations was incorrect.
