MueLu: remove old tutorial.

There is a refurbished new tutorial in the MueLu pubs repository.
[NOX] DEPLIBS -> TESTONLYLIBS (in the tests)

This removes all new TriBITS warnings.
[Belos] correct usage of DEPLIBS in tests

This removes the new TriBITS warnings.
[Belos] Use TRIBITS_SUBPACKAGE for Belos

This commit is actually smaller than it looks: A few updates to the CMake
infrastructure enable the use of TRIBITS_SUBPACKAGE() for Belos, breaking up
the package into Core, Tpetra, Epetra subpackages. This has several advantages,
one of them being a finer-grained access to the dependency structure. Now, for
example, only package dependent on BelosTpetra also get linked to Tpetra.

[MueLu, Tpetra] make use of ADDED_LIB_TARGET_NAME_OUT

This fixes the property setting on MueLu, Tpetra libraries if a library prefix
is present.

SEACAS: Test executables seem to still need DEPLIBS settings
LOCA::Stepper::finish(): For now, revert a return case to original.

I need to think more about how to signal the use of the extra continuation step
in finish(). For now I reverted it to its original behavior because I broke some
LOCA tests (sorry!).

Sacado:  Make Taylor(int) explicit to prevent bad implicit conversions.
TrilinosCouplings/FENL:  Add spatial coordinates for repartitioning.

I haven't tested whether the repartitioning actually works as expected
yet.  It is a litte weird for the ensemble/pce cases that the
coordinates are stored using those scalar types.
Sacado:  Add include of <cmath> in Sacado_MathFunctions.hpp for clang.

Sacado has not compiled with recent versions of clang (most notably the
default compiler on recent versions of Mac OS X) because of this error:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/cmath:664:35:
error:
      no matching function for call to 'fabs'
      abs(double __x) _NOEXCEPT {return fabs(__x);}

Simone Rossi figured out that this can be fixed by adding an include of
<cmath> in Sacado_MathFunctions.hpp.  I tried this on Mountain Lion and
it does indeed appear to work, and also appears to not cause any
problems with GNU.
MueLu: Modifications to the RefMaxwell interface

Adding a (private) initialize method and several new constructors.
Also addding some exception handling (don't know if MueLu developers
like this) to protect a possible null pointer error if add on's are
needed.
Belos:  Fix dependencies for BelosEpetra adapters subpackage.

Recently Nico refactored Belos into subpackages.  For the TSQR support,
it is actually necessary for the Epetra adapters subpackage to depend on
Tpetra, since that is where the Epetra TSQR adapter lives.  So I added
an optional dependency for this subpackage on Tpetra.
Stokhos:  ptrdiff_t -> std::ptrdiff_t.

Not sure why this just cropped up now.
Stokhos:  Fix now invalid usage of DEPLIBS.
Sacado:  Fix now invalid usage of DEPLIBS.
TrilinosCouplings:  Fix now invalid usage of DEPLIBS.
