Fix the name of SNESReasonView() and SNESReasonViewFromOptions() to PETSc standards
Remove the format argument from KSPConvergedReasonView() since it is not needed and inconsistent with the SNES version,
plus the previous release did not have this argument.

DM+SNES: Preliminary adaptive interpolation
- Using the scheme from BootstrapAMG with some modifications to apply to GMG
- Moved adaptive interpolation into DM from Plex
- Added event for adaptation
DM+SNES: Preliminary adaptive interpolation
- Using the scheme from BootstrapAMG with some modifications to apply to GMG
- Moved adaptive interpolation into DM from Plex
- Added event for adaptation
- Added routine to check an interpolator
- Added viewer for coarse and fine vectors used for interpolation optimization
- Add coarse space determined by eigenvectors
- Right now adaptive interpolation is unweighted

PCMG: Added adaptive interpolation
- Added coarse vectors to resolve at each level
- Added adaptation flag and API
- Added option -pc_mg_adapt_interp to turn on adaptation
- Use -dm_interpolator_adapt_k to set subspace size and -dm_interpolator_adapt_use_poly to select type of functions
- Doc fixes for functions
- Fix options for construction of a vanilla coarse space
- Require Galerkin matrices for adaptive interpolation
- Fixed problem with composed eigenvalue
- Normalize eigenvector in smoothing loop
- Added option to use generalized eigenvector basis (For some reason, this is worse on test problems)
- Make adaptive allocation happen only initially, protect adaptive functions from invalid levels

Slightly improved the handling of PCFailedReason on multiple ranks
pc->failedreasonrank now contains the failed reason from the current rank
pc->failedreason continues the unified common value collected in KSPCheckNorm/Dot
This parallel code can check the common value and be sure to do the same action on each process
Also printed message now provide the accurate value instead of the value on rank 0
Changed KSPReasonView() and KSPReasonViewFromOptions() to KSPCOnvergeReasonView() and KSPConvergedReasonViewFromOptions()
Added the PetscViewerFormat argument to the public KSPReasonViewFromOptions() and removed the private function
Removed some off the PCFailedReaon processing code from KSPSolve_PREONLY since buggily assumed the same reason all ranks
The error message on KSP failure now also prints the PCFailedReason if appropriate
Needed to add a new alt file
