[Galeri] rename iohb.* to Galeri_iohb.*

This is to avoid header file clashes with header by the same name, installed
in the same include directory.

Partly fixes bug #6091.
[TriUtils] rename iohb.* to Trilinos_Util_iohb.*

This is to avoid header file clashes with header by the same name, installed
in the same include directory.

Partly fixes bug #6091.

Tpetra:  Make k_rowPtrs_ const.

This fixes an incompatibility between k_rowPtrs_, which was a non-const
view, with the Kokkos::StaticCrsGraph, whose row offsets array is const.
I made k_rowPtrs_ const and added a second typedef, t_RowPtrsNC, for the
non-const version which is used internally in a few CrsGraph and
CrsMatrix methods.

This gets TrilinosCouplings/FENL with MueLu working again.
Fixed an error in the parallel execution of Ifpack2 Relaxation using
block CRS matrices. An incorrect point map was being used to initialize
the vector. We now take an alternate approach to initializing the
block multivector.

Anasazi: Added AnasaziSpecTransStatusTest.hpp to HEADERS in CMakeLists.txt
Anasazi: added tests for TraceMin(-Davidson) and fixed a bug in TraceMin.

The new tests test TraceMin's ability to solve the standard
eigenvalue problem without preconditioning.  All three saddle point
solvers are tested, as well as spectral transformations for computing
the largest eigenpairs of a matrix.  I will add tests for the generalized
EVP and preconditioning later.

The bug in TraceMin was this: at each iteration, we compute
an update \Delta for the current iterate, then take V=Y-\Delta.
TraceMin was computing V=Y+\Delta.

Also made minor cosmetic adjustments to the code.
Anasazi: TraceMinDavidson: Fixed build error.

Calls to a templated abstract base class' methods need to have
"this->" in front of them.  Older versions of gcc let them through.

Mark Hoemmen says: We need to get the build error fix in, so we
are forcing the push.  Direct any concerns to him.

Stokhos:  Update Belos adapters for UQ scalar types.

Now that norm1 and normInf have Kokkos implementations, we can simplify
the Belos traits.
