DMPlex ex4: Test for hex refinement now working
- Fixed deadlock with parallel test

DMPlex: Fix support of face edges using orientation info in hex refinement

DMPlex: Fix interiors faces in hex refinement

DMPlex: Get correct support for split faces by using orientation info in hex refinement

DMPlex: Properly orient split faces in hex refinement

DMPlex: Fixed bug with numbering subcells in hex refinement

DMPlex: Added GetQuadEdge_Static() and GetQuadSubface_Static()
- This is my nice way of getting parts of orientated mesh pieces

DMPlex: Fixed leak in refinement

DMPlex ex3: Removed generator stuff, fixed output
- I think more precise tabulation delivers smaller discretization error

DMPlex ex5: Fixed leaks

doc: restore functions in PETSc zero their arguments

This is done to prevent accidental misuse. In general, one can pass
NULL for the pointer argument to keep the pointer around for longer, but
use

doc: restore functions in PETSc zero their arguments

This is done to prevent accidental misuse. In general, one can pass
NULL for the pointer argument to keep the pointer around for longer, but
use of arrays after restoration is invalid.

GNU Make (v3.81 or later) is now the default build, --download-make is supported.

* jed/gnumake: (44 commits)
gmake: put object files in obj/ instead of obj-gmake/
gmake: make is no longer at config.programs - so remove old usage of self.make
gmake: pass gmake to mpich/openmpi configure [fixes --download-mpich]
gmake: fix --download-triangle [do not overwrite self.make set by package.py]
make: reduce default verbosity of gnumake build
make: use SL_LINKER_SUFFIX (Mac uses .dylib)
make: change formula to compute make_np [from number of cores] Also remove special code for Barry [probably needed by an a laptop older than his current]
gmake: workarround if FC_MODULE_OUTPUT_FLAG is not found
gnumake: make it the default build mode
make: fix usage from programs.make to self.make [via packages.py]
make: clean up integration of programs.make into make.py
download-make: migrate prior 'make' detection code from programs.py to packages/make.py
download-make: add initial support. [yet to migrate stuff from programs.py]
win32fe: updated binaries now handle 'lib @cmdfile' and 'cvf/ifort -module:PATH'
gmake: read ./conf/petscvariables when not in environment
gmake: support for AR using win32fe response files
__SDIR__: use empty string instead of NULL
config: dependency flags are only needed by compiler, so skip linker test
config: add dependency flags for most compilers
__SDIR__: set to NULL, ignoring __INSDIR__ which is now unnecessary
