Merge branch 'stefano_zampini/feature-convert-matnest-matis' into stefano_zampini/feature-pcbddc-saddlepoint

I have to merge it here, since there's an API addition for MatIS in stefano_zampini/feature-pcbddc-saddlepoint
that prevents me to smoothly merge stefano_zampini/feature-convert-matnest-matis into next.

This will also facilitate merging stefano_zampini/feature-pcbddc-saddlepoint into master

SNES: Add flag indicating if final residual is always computed

Although SNESSolve_XXX always updates the solution variable, it may not
be the case that the residual in vec_func is the residual at the new
solution. Track this behaviour explicitly for all concrete
implementations. We will use this in SNESSolve_FAS to determine if the
residual must be computed before transferring it between levels.

Merge branch 'tisaac/ts-ex11-amr'

We now have an example (ts/examples/tutorials/ex11.c) where we can
use either DMPlex or DMP4est to handle adaptivity when time stepping.
We have tried to minimize the amount of code that is specialized to the
different DMs, and in the future more work can be done to improve this
interface.

* tisaac/ts-ex11-amr: (62 commits)
DMP4est: type fix
Plex: Fixes for analyzer
DMP4est: update snes ex12 regressions
DMPlex: fix parent/child interpolation with numFields > 0
DMP4est: also compute anyChange for uniformly refined/coarsened meshes
TS ex11: fix command line for AMR without computed gradients
TS ex11: remove gradient reconstruction from adaptivity requirements
DMPlexTree: some compilers want this var initialized
Plex: Changed Get/RestoreFaceFields() and Get/RestoreFaceGeometry() to return the number of active faces - This fixes a long-standing bad access in FV, although the values were never actually used.
DMPlexTS: removed unused variables
DMPlex/DMP4est: small fixes for next warnings and errors
SNES ex36 and ex52: These do not work anymore
DMPforestGetTransferSF_Point(): try to match parents
PetscViewerHDF5: destroy old file data if setting new filename
DMPlex + FV: remove leaky references in projection functions
Plex: Fixed incredibly stupid bug in Jacobian computation
PetscViewer HDF5: added get name method
DMPlexTree: do not skip out of child matrix loops early
PetscFV: correct field offsets when limiting gradients
