Brought this back up to nekbone-3.0

The preconditioner is still just a copy, though renamed, so no
change there.

The only real change to driver was putting a bootstrap call to
maskit before cg_cuda_init.  That mask is then copied to the gpu
and used to properly implement maskit.

This passes both single and multi-core.

This will fix some line ending problems that cropped up.
Normalize line endings
Merge branch 'gpu-all' into gpu-maxhutch

Nothing substantial to resolve here.  Logs will be a bit messy
with some ongoing CR-LF issues.

Code falls back to old implementation for nx1 != 9,12.

Still a bit messy, but getting better.
