Removes VECCUSP vectors and AIJCUSP matrices, because they provide no added benefit over VECCUDA and AIJCUSPARSE.
Also removes the CUSP-based preconditioners for now.
SACUSP will be re-added later, after the new release is out.

Merge branch 'jose/aijcusparse-fix'

* jose/aijcusparse-fix:
Fixes problems in MatMult and MatTransposeMult for matrices with empty rows when using -mat_type aijcusparse.
The fix is to initialize the result vector with zero, which has some performance overhead.
Arguably, this is a bug in cuSparse, which we have to circumvent here.
