This commit
- MatMarkDiagonal_SeqAIJ/ELL()
- now use change in mat->nonzerostate to determine if it needs to recheck the diagonal locations
- sets diagDense flag for a complete diagonal
- MatInvertDiagonal_SeqAIJ/ELL()
- now uses change in mat->state to determine if diagonal entries and inverses need to be recomputed
- name changed to MatInvertDiagonalForSOR_SeqAIJ/ELL() for code clarity
- Added MatInvertDiagonal_SeqAIJ_Inode() for use by MatSOR_SeqAIJ_Inode()
- now uses change in mat->state to determine if block diagonal entries and inverses need to be recomputed

Gather CUDA lib includes in petscdevice_cuda.h + disable cuSPARSE warnings using DISABLE_CUSPARSE_DEPRECATED

Defining DISABLE_CUSPARSE_DEPRECATED is Nvidia's recommended way of disabling cuSPARSE warnings
This avoids requiring -Wdeprecated-declarations - that can mask other (non-cuSPARSE) warnings
