This PR changes the interface of sized_cost_fucntion,
autodiff_cost_function and numeric_diff_costfunction from using ten
hardcoded parameter blocks to a variable number of parameter blocks
using variadic templates.
Trailing parameter blocks of size zero are now considered as error.

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.

The interface for NumericDiffCostFunction and AutoDiffCostFunction
are not comparable. They both accept variadic functors.
The change is backward compatible, as it still supports numeric
differentiation of CostFunction objects.
Some refactoring of documentation and code in auto_diff_cost_function
and its relatives was also done to make things consistent.
