Mat: get rid of the valid_GPU_matrix flag from the interface
A specific implementation may provide those operations on GPU
The previous interface would have invalidated the data
MatAssemblyEnd_MPIAIJ now takes care of propagating the correct
flags to the blocks if we set its flag to OFFLOAD_CPU
This is to fix the case of MatFDColoring, which do not use the MatSetValues interface

Non-numeric optimizations focused on AIJ, MatFDColoring, and DMCreateMatrix_DA_*AIJ, looking to improve performance in GPU environments
1) PetscCalloc*() now uses system calloc()
2) Merged some PetscMalloc*()
3) Eliminated unneeded PetscCalloc*()
4) Removed some memory allocations and copies in MatFDColoringSetUp(), added local variables for better compiler optimization
5) Added MatSetValues_SeqAIJ_SortedFull(), added MatSetOption(MAT_SORTED_FULL)
6) Optimized DMCreateMatrix_DA_*AIJ for nonperiodic case to automatically have sorted columns (faster MatSetValues() times)
7) Eliminated call to PetscMemzero() in PetscFree()
