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.

For historical reasons we had a "using namespace std;" in port.h. This
is generally a bad idea. So removing it and along the way doing a bunch
of cpplint cleanup.

1. Complete restructuring of the documentation to account for
GradientProblemSolver.
2. Update the version history to account for changes since 1.9.0.
3. Add links and document the various examples that ship with ceres.
4. Documentation for GradientProblem GradientProblemSolver.

Inner iterations by default would use problems where the evaluator
was configured to use exactly one thread for doing the evaluation.
This is fine when there are multiple inner iteration problems
being executed concurrently, but every now and then there are
problem decompositions where there is just one parameter block
in the current independent set and it touches every single
residual block. In such cases it is essential that the evaluator
be configured to use multiple threads.
We now pay attention to the size of the independent set and
dynamically configure the number of threads being used by the
outer loop and the evaluator loop.
Thanks to William Rucklidge for reporting this issue and providing
a test problem to debug.

This is a intermediate change to clean things up
in preparation for a broader refactoring of the SolverImpl.
Essentially we are replacing raw pointers in Minimizer::Options
with shared_ptr objects. For now this only makes things a bit
more complicated looking inside solver_impl.cc, but going
forward this will lead to considerable simplifications in
tracking ownership of various pointers.

Inner iterations require specific constraints on parameter
block orderings. The creation and validation routines for
these orderings are not static methods in CoordinateDescentMinimizer.

Add Minimizer::Options::is_silent which allows the user
to turn off the logging inside the minimizer completely.
In particularly this is used for silencing the logging
when inner iterations are used.
Add VLOG_IF to miniglog.

Add automatic recursive independent set decomposition.
Clean up the naming and the API for inner iterations.
