Merge branch 'barry/fix-nonew-notcollective/maint' into jed/mat-assembly-perf

Jed this fucking 6+ month running thing in next that is not in master is a royal fucking pain in the ass and
an abuse of git. I think it is not justified to ever have anything in next for more than a few weeks at most.
Either take it out of next if it is broken or put it in master if it is not broken. Hanging around in next but
not master for ever is not a good policy.

Merge branch 'master' into mesgarnejad/feature-plex-globaltonatural

* master: (111 commits)
add filters for website tests that removes warnings about MPI type tag mismatches due to const
remove Peter from blame-email list.
don't warn about MPI const long * versus long long *
Configure: Added GMP an MPRF - These allow arbitrary precision arithmetic
SNES ex69: SolCx finally works - Fixed order of parameters - Made different versions of pointwise functions
SNES ex69: Fixed bug where SolKx and SolCx have different numbers of parameters
SNES ex69: Small bug fixes - Initialize coordinates for SolCx - Fixed declaration length
I believe this call on line 357: ierr = DMSetFromOptions(dau); should actually set `dak`. The DM `dau` is already set on line 349.
SNESSolve_KSPOnly() did not compute function at new solution unless monitoring is turned on but SNESSolve_FAS() internals assume that each subsnes solve it calls does compute the new function value so broke when -fas_levels_snes_monitor was not turned on but -fas_levels_snes_type kspmonitor was used
Have SNESVIGetInactiveSet return the *actual* current inactive set.
One now passes the nullspace in the matrix for a linear system as the first Amat argument to KSPSetOperators, SNESSetOperators, TSSetIJacobian() not the second pmat argument
Remove change documentation of Removed MatMFFDAddNullSpace() just use MatSetNullSpace() as it is now backported in maint (36.html)
MatMFFD doesn't need to have its own null space management cherry-picked from 39601f4 (barry/remove-matmffdaddnullspace/master)
Removed trailing '\\' in the authors line.
add note to PetscOptionsInsertFile() that it should not be used for PETSc wide options
Add Fortran stub for SNESSetUpdate()
improve manual page slightly for clarity
PCGASM.
Basic PCGASM description added to manual.
