MPIPtAP: implement all-at-once algorithm
scalable and nonscalable just take too much memory since they cache the intermediate data structure.
The all-at-once algorithm do all caculations at once without caching any data. It saves a lot of the memory
There are two implementations: allatonce and allatonce_merged
``allatonce" overlapp the communication and the computation with taking a few extra operations.
``allatonce_merged" do all caculations together for remote and local parts.
Both are memory friendly

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.

bugfix for MatView_MPIAIJ_PtAP() as reported by Stefano Zampini.
When MatView a matrix Amat which is a duplicate PtAP, it should call base MatView_MPIAIJ() because MatDuplicate only creates base matrix (see Note). However, it calls MatGetOperation(mat,MATOP_VIEW,&viewf); MatSetOperation(B,MATOP_VIEW,viewf); i.e., it copies old matview ops. This patch fix the bug.
