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.

Now that the trust region minimizer depends on the line search
minimizer, conditional compilation of the line search minimizer
will lead to build breakages, so this option is now not available.
It is not expected to have as significant impact on users as the
amount of code in the line search minimization algorithm is
rather small to begin with.

- Previously line search was sparse in terms of debug orientated VLOG
output which made debugging failure cases difficult.

- These messages were originally VLOG(2) and were mistakenly upgraded to
WARNINGs when the tolerances were reduced.

- Improves performance of BFGS on NIST, as per L-BFGS.
- Adding explanation of origin and purpose of Secant condition
tolerance check for Hessian update in (L)BFGS.

1. Add -DLINE_SEARCH_MINIMIZER to CMake to make the line search
minimizer optional.
2. Better handling of -DSUITESPARSE/-DCXSPARSE in top level cmake
file.
3. Disable code which will never be used if SuiteSparse and/or
CXSparse is not available.
4. Update build docs.
5. Update jni/Android.mk
6. Minor lint cleanup from William Rucklidge.
Change-Id: If60460a858000df82faed7a6bb056dd2bfdde562
1. New LineSearchDirection interface, factory and instances.
2. Cleanup of LineSearchMinimizer to use the State and Direction objects.
3. LBFGS -> LowRankInverseHessian.
4. Refactoring of the RunCallbacks function and share it across
LineSearchMinimizer and TrustRegionMinimizer.
