Configure: I really hate exceptions - We should rewrite this to eliminate all exceptions in favor of return codes
Configure: I hate exceptions
fix typo for 'runex19_superlu_dist_2'
Fix for freeing just what needs to be free when SuperLU_Dist factorizations reused
Updated to latest hypre pre-release with fixes for handling blas/lapack libraries
Switch back to petsc fork of SuperLU_Dist that turns of use of findMPI
PCFactorSetUpMatSolverPackage() should not crash but instead produce a useful error message if called before it is in the proper state.
Clarify that SNESGetLinearSolveIterations() does not include failed iterations.
User reported issues with downloading boost using the previous URL but not this one
Configure: Small change to log order
MatFDColoringSetUp_MPIXAIJ: fix broken initialization of colmap
Bib: Missing comma
add support for binary viewer for -ts_monitor that records time at each timestep
superlu_dist: set MPI_C_COMPILER etc options - so that superlu_dist cmake does not look for a different/incompatible mpi compiler. [and its CFLAGS].
remove reference to VecGetValuesBlocked() and VecGetValuesLocal() from manual page since they do not exist.
Stop configure if user builds with threadsafety and debugging on
Added configure option --with-viewfromoptions=0 which will speed up code with many small solves substantially
Only generate list of all PetscFunctionLists generated in debug mode since in some circumstances where many objects are created searching this list is very slow.

Merge branch 'hzhang/dmnetwork-spJacobian'

Have DMNetworkGetVariableGlobalOffset() output actural offset value at ghost point

Merge branch 'master' into barry/add-pcfieldsplit-logevent

fix build warning

final cleanup

cleanup DMCreateMatrix_Network()

factor MatSetUserblock_private() for code reuse

bugfix: typo

enable user jacobian for supporting edges

reorg to enable user provide or !provide jacobians

use DMPlexPreallocateOperator() for preallocation

add missing coupling block; start adding matrix preallocation info

add blocks for connected vertices

continue working on DMCreateMatrix_Network() -- vertex blocks are implemented without using JPlex

continue working on DMCreateMatrix_Network() -- edge blocks are implemented without using JPlex

replace dense blocks of DMPlex matrix with user-provided sparse matrices in DMCreateMatrix_Network()

Merge branch 'master' into tisaac/dmforest

* master: (136 commits)
Make error message specific to exactly what matrix is supported
Prevent fblaslapack or f2cblaslapack from being compiled with the -no-prec-dev Intel compiler option since it can produce incorrect results
Fix for PCReset_HYPRE to make it reentrant.
replace default superlu_dist '-mat_superlu_dist_colperm METIS_AT_PLUS_A' with MMD_ATA to avoid different random numbers for nightly tests
fixes for merge from maint patch
Added PCReset_HYPRE() so it may be used with SNESVI solvers
remove Microsoft compiler message for paste macros used for handling Blas/Lapack macro name mangling for example
Increase the number of PetscViewerPushFormat() possible to 25 and use a macro PETSCVIEWERFORMATPUSHESMAX for the value
Configure: Remove redundant logging
Bib: Added ref
nightlybuids: fix permissions of script
MatRegisterDestroy() does not exist but it is listed in manual pages
externalpackages-git: save local changes if any - in git stash - before 'git checkout -f' Useful incase --with-package-commit=HEAD option was msissing [perhaps due to a typo]
nightlybuilds: add xsdk builds
Add architectures for testing xsdk package downloads (Trilinos, Hypre, SuperLU)
create another version of TurnForward() for adaptive time stepping specifically
Configure: Give proper default if HOME is missing from the environment
fix abbreviation
allow zeropivot for MatSOR_SeqAIJ_Inode, node size=1
add test case using adpative time stepping for checkpointing type 'NONE'
