Thank you for the changes. I am especially pleased to see that we now have support for QUDA. I look forward to trying it out.

Commit Summary
Provide return values for the top-level API.
Added su3_eigen_asqtad.Grid.2 test data
Reduced the tolerance parameter for su3_eigen_hisq.Grid.2 test because the Lanczos run may fail depending on the system. In Lanczos algorithm, eigenvectors' maximum precision get lower from the machine precision as iteration continues. I believe it is due to the error accumulation.
Put missing return keywords. Add finalize_grid() to the end of ks_eigen.
Run free_lattice() at the end of ks_eigen. Other applications may also need this fix.
Add QUDA Lanczos eigensolver support.
Add test samples for ks_eigen_asqtad and ks_eigen_hisq with QUDA eigensolver
Remove Nev parameter
modify QUDA verbose option
modify su3_eigen QUDA test samples
fix comments and outputs

I added a wrapper for QUDA Lanczos eigensolvers; thick restarted Lanczos and thick restarted block Lanczos. Also fixed a few minor bugs related to the Grid wrapper.
