Bug fix in DMDAGetReducedDA

Hg-commit: 6240a18647e1132da52a0bd94a9b8a72d39eafcb

Added new FEM functions for DA
- Remove requirement that coordinates for DA have a given blocksize
- DMDASetUniformCoordinates() now works with PetscSection version
- Added dageometry.c which has DMD

dmrefine and coarsen for DA must not change the N and P for lower dimensional problems since the other code depends on them always being 1

curse whomever is assuming their changes are breaking thing

Port field names in DMCoarsen_DA, as is done by DMRefine_DA

DM CHANGE: DMCreateFieldIS() and DMCreateLocalToGlobalMapping() now use the default PetscSection
- DMComplex uses this
- DMDA now uses section for DMCreateMatrix(), but preallocation does not work

Fixed for flexible DA in parallel

Hg-commit: 6c2e217ad8b431f9c4ef53f9649d0bfd2776de21

DM CHANGE: Now DMGlobalToLocalBegin/End() and DMLocalToGlobalBegin/End() use the default PetscSF if present
- DMComplex now uses these

Hg-commit: 6fdfec99b8fc8426d2b385cbe72264449a63e681

DM CHANGE: Moved PetscSections describing layout and PetscSFs describing overlap int DM
- This allows unstructured layout on any DM, in particular DA
- Creation flows goes localSection --> pointSF --

DM CHANGE: Moved PetscSections describing layout and PetscSFs describing overlap int DM
- This allows unstructured layout on any DM, in particular DA
- Creation flows goes localSection --> pointSF --> globalSection --> dofSF
- DMGetGlobalVector() and DMGetLocalVector() use these layouts if they exist (DMComplex uses this now)
- Put in DA code for creating the Section and SF
- Cleaned up some memory problems
