PCBDDC: Separate deluxe subproblems

Recompute_topography now drives the setup/reuse of deluxe
There's still something which does not work properly when some subdomain faces are made up by just one element face
There's no need to extract B0_R and B0_V separately
Solved a couple of bugs with pcbddc->switch_static = PETSC_TRUE

PCBDDC: adaptive selection of constraints now works without explicitly changing the basis on the velocities

PCBDDC: construct a fake change of basis that will be needed if we want to use deluxe scaling withouth change the basis on the pressures

The added code also goes in the direction of supporting a mix

The added code also goes in the direction of supporting a mix of user-defined constraints and adaptively generated primal spaces.

Merge remote-tracking branch 'origin/knepley/feature-plex-add-time' into tisaac/dmforest

Both branches changeds DM projection behavior, so I wanted to sort it
out before merging

* origin/knepley/feature-plex-add-time: (59 commits)
SNES ex69: Updated to new function API, fixed test output
SNES ex75: Fixed for new function API
add fortran stub for TSMonitorLGSetTransform() and fix TSMonitorLG for multiple fields but no names provided for fields
add -binary_write_double so __float128 precision can save as double to binary files
TSClone() did not clone Fortran function pointers hence some TS methods would fail if functions provided in Fortan
petsc4py: update to snapshot with 'barry/petscoptions-object' changes
fix bad merge that introduced 2 copies of the MPI_Comm_free()
update example to use MAT_INPLACE_MATRIX, not REUSE
incorrect addition of float to PetscInt
update for new PetscOptions API
TS ex18: Fixed function API and test output
Function now takes PetscOptions as first argument, this was missed during the first round of updates
bugfix for MatSetOption_Elemental()
fix test example no change output that was missing a line
fixes for new PetscOptions.. API that are needed based on problems with nightly build
Plex ex3: Use new function API
SNES ex62: Use new function API
SNES ex12: Use new function API
Plex: Fixed unused options in examples
Plex+DMDA: Add time to signatures

mark variable as unused so compiler doesn't warn about unused value

petsc4py: revert to manually syncing petsc4py with petsc master changes
configure: revert gitcommit default value to Null. If a pacakge using giturl does not change this value - raise an error
fix: revert change in a44bcdf that breaks with pgf90
update test output for fixed to hypre interface that now actually pass the interp vectors to BoomerAMG
fixes for merge from Jed's branch that should have been merged into master months ago!
Add to changes dev.html file the change to the PetscOptions routines

fix: revert change in a44bcdf that breaks with pgf90
update test output for fixed to hypre interface that now actually pass the interp vectors to BoomerAMG
Error message should say use negative threshold value to prevent filtering out zeros
Calls to HYPRE_BoomerAMGSetInterpVectors() did not actually copy the vector data pointer from the PETSc vector to the hypre vector thus resulting in the hypre interp vectors being identically zero and hence not affecting the quality of the AMG hierarchy produced/
DMPlex: Silence overzealous compiler warnings
add row/col orientation to MatConvert_Elemental_Dense
fix formatting error in previous commit [broke nightlybuilds]
fix formating of TSTHETA manual page and add missing command line option
run hwloc with MPIEXEC and binding so it runs on the correct machine
fix: memory leaks [in valgrind test]

Merge branch 'master' into knepley/fix-examples-plex

* master: (112 commits)
correct expression for implict ODE/DAE in table 11 of users manual
remove warning about deprecated MPI call in examples
rm variables declared in middle of subroutine
tolerance for equality in PETSc test should depend on machine epsilon
tolerance for acccuracy in test example should depend on machine epsilon
increase convergence tolerance to get same result in single precision as double for convergence history
update no change output for gasm test which had not been properly updated
remove C++ // comment
example mistakenly used MPI_COMM_WORLD as if it was rank in print statement thus producing output only with MPI Uni
grep out name of DM object since on some systems the address printed has extra zeros thus producing a false difference in output
increase tolerance for test example
build: revert el6-4 build to cg - as el6 compilers give link errors
fix error type
insure similar convergence history for single, double, quad
fix ex104.c based on Barry's suggestion
increase example convergence tolerance to get matching convergence history in single and double precision
increase convergence tolerance so that test example has similar convergence history in single and double precisions
changed from cg to gmres for eigenestimator since in single precision cg produced a possible indefinite matrix report
change test example tolerance to depend on machine epsilon so as to give correct results in various precisions
loosen convergence tolerance to have similar convergence history with single, double, quad precisions
