No more batch submission script; this is all due to a very smart idea of Lisandro Dalcin

*) removed or fixed all remaining --know-xx options that required a batch submission script
*) removed all details of --known-size-- that are no longer needed
*) cleaned up BAIJMKL source code, made it work with the rest of PETSc and removed is
dependence on a batch submission script, added test case for BAIJMKL
*) update the installation guide on batsch submissions and OpenMP
*) print MKL version, print OpenMP usage with mkl_sparse options

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()
