A Ceres Context holds common global state that can be re-used within
Ceres. The Context current contains a thread pool if compiling with
C++11 threading support. Threads are expensive to create and destroy so
it is good to maintain across multiple Ceres solves.
Tested by compiling with and without TBB support and ran unit tests. Ran
bazel as well.

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.

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