This optimized C kernel is not used in the GPU classes, so it is safe to skip its declaration

Fix a MatSetRandom bug with unassembled MATMPIAIJ
When doing MatSetRandom on a preallocated but unassembled matrix X, we can not
simply calling MatSetRandom on X's B. Since B is not assembled, it has a column
size as wide as X. Calling MatSetRandom(B,r) might generate nonzeros belonging
to X's A.

MPIPtAP: Enable large-scale simulations
The old code uses a global size of columns when creating the local matrix
This uses a lot of memory when calling MatMatMultSymbolic_SeqAIJ_SeqAIJ
We here compact out many extra columns, and construct a new local size.
