Fix bugs with locks imposed upon vectors in VecScatterBegin/End
Athough otherwise one can potentially overlap computation/communication in MatMultTranspose_MPIAIJ,
MatMultTransposeAdd_MPIAIJ, that is based on the assumption that the scattered data is not written
to the destination vector until VecScatterEnd(). This assumption is too strict for implementation
of VecScatter and could lead to wrong results. For example, the origin MatMultTransposeAdd_MPIAIJ is
wrong with -vecscatter_merged. In addition, the assumption is not stated in petsc user's manual.

Merge branch 'haplav/feature-mataij-load-from-hdf5' [PR #1232]
* haplav/feature-mataij-load-from-hdf5:
MatLoad() implementation for HDF5.
This PR done with cooperation with @Mari Pecha brings the HDF5 matrix loader.
Its impact is twofold:
- It introduces a truly parallel reader where each rank reads its chunk of the matrix.
- It can directly read MATLAB's native MAT-file format (version 7.3) which is in fact an HDF5 flavor.

MatSetOption_MPIAIJ: No need for handling symmetry flags here.
They are handled directly by MatSetOption().
And they don't affect preallocation so no need for MatCheckPreallocated()!
