Since Ceres is moving to using GitHub for issues, and the Google
Code URL in the current copyright header will soon become invalid,
update all the headers.

- Previously we had no defined default value for
sparse_linear_algebra_library_type in Solver::Options if Ceres
was compiled with no sparse library available. Thus in that case,
the default value (dependent upon the compiler) would indicate that
one was available.
- Now we have an explicit option that means no sparse library is
available, which is now the default value in Solver::Options in this
case.
- Add a warning in CMake when the user disables all sparse libraries.
- Fix typos in trust_region_preprocessor_test:
(SUITE/CX)_SPARSE -> (SUITE/CX)SPARSE that induced failures when
no sparse libraries were available.

Alternatively, if quiet_NaN is not available on all platforms a workaround would be:
volatile double zero = 0.0;
double x = 1.0/zero;
The 'volatile' is needed to shut up "warning C4723: potential divide by 0".

TrustRegionPreprocessor was not setting Minimizer::Options::is_constrained.
This meant that the line search for bounds constraints was not being
invoked for bounds constrained problems.
And some minor lint cleanup.

1. Base class for preprocessors.
2. A preprocessor for problems that will be solved using
the trust region minimizer.
3. Added sanity tests to the program reordering options
for Schur type linear solvers.
4. Tests for the TrustRegionPreprocessor.
