Keir Mierle 7492b0d8de Update copyright headers with new year and URL 
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.

Sameer Agarwal 0338f9a8e6 ITERATIVE_SCHUR works with no f-blocks. 
When the Schur complement is of size zero,
i.e. none of the parameter blocks interact
with each other, the ITERATIVE_SCHUR linear
solver crashes due to some checks that are
triggered in the SCHUR_JACOBI preconditioner.

This patch adds logic to detect this condition
and to deal with it and adds tests that verify
the fix.

Thanks to Soohyun Bae for reporting this bug.
