Merge branch 'master' into knepley/feature-fem-dgspace

* master: (593 commits)
Bib: Added Top500 and fixed entry
fun3d: update PetscMallocValidate() usage
bib: rename ref with duplicate key
Webpage: Corrected '-dm_mat_type cusp' to 'dm_mat_type aijcusp'.
Allow calling MatGetBlockSize[s]() before matrix preallocation
SNESLINESEARCHBT: Set the norms when exiting early due to negligible step.
SNESQN: only monitor real part of dot product (fails with C++ complex)
Corrected the #include statement in the man pages for the PetscObjectComposedDataSet/Getwhatever routines.
DMPlex: Added doc for DMPlexGetHybridBounds()
winzip: detect if winzip is used to extract petsc.tar.gz and error out.
configure: remove self.archIndependent as its not being used. [it is used to create externalpackages/package/arch dir which is unused]
configure: fix packages using package-dir/PETSC_ARCH as out-of-source-build location Perhaps this should be changed to package-dir/build?
configure: remove dead code previously used to download BuildSystem
configure: check if compilerDefines [and compilerFixes] exist in framework before using them
configure: save/restore reconfigure.py when --with-clean is used
configure: add --with-clean option to delete buildfiles/externalpackages in PETSC_DIR/PETSC_ARCH and potential externalpackages in --with-external-package-dir/PETSC_ARCH
configure: With --with-externalpackages-dir=dir store/build packages in dir/PETSC_ARCH
Add MatSeqSBAIJSetPreallocationCSR()
configure: switch to using PETSC_DIR/PETSC_ARCH/externalpackages by updating package.py to use externalpackages.py as the externalPackagesDirProvider
configure: move dead code configureExternalPackagesDir() from petscdir.py to externalpackagesdir.py Also set PETSC_DIR/PETSC_ARCH/externalpackages as the externalpackagesdir

Mat: remove third argument to MatNullSpaceRemove

Out of place removals were dangerous because the MatNullSpace held the
only reference to the resulting Vec, which is dangerous. This use case
is rare (never used in PETSc itself) and can easily be accomplished:

VecDuplicate(x,&y);
VecCopy(x,y);
MatNullSpaceRemove(nullsp,y);
