Merge branch 'tisaac/dm-label-promote' into tisaac/dmforest

* tisaac/dm-label-promote: (319 commits)
snes tutorial ex69: give mesh a name for regression purposes
DM: make DMLabel labels a part of all DMs
builder: update regression tests
builder: update some missing package requirements
DM: set coordinate vector name
ts tutorials ex11_sa: make it compile
mark variable as unused so compiler doesn't warn about unused value
configure: use 'git cat-file -e' to check for existance of a commit in localrepo. ['git rev-parse' does not give error for a hash thats not in repo]
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
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

Introduce MPIU_Allreduce() to detect cases where all processes that share an MPI comm do not call the same sequence of MPI_Allreduce()
This is a bug that can be difficult to track down.

Merge branch 'maint'

If only some processes had no local entries in the matrix the MatSeqXAIJPreallocation() changed the value of aij->nonew on only those
processes thus resulting in gridlock in MatAssemblyEnd_MPIXAIJ()

If only some processes had no local entries in the matrix the MatSeqXAIJPreallocation() changed the value of aij->nonew on only those
processes thus resulting in gridlock in MatAssemblyEnd_MPIXAIJ() since some processes wanted to update the matrix nonzero state while others did not

MatHeaderReplace() corrupted the -objects_dump array

Reported-by: Torquil Macdonald Sørensen <torquil@gmail.com>

MatHeaderReplace() and MatHeaderMerge() destroy the second matrix argument therefor pass it as
a pointer to it can be zeroed and not mistakenly reused.
