Some Fortran stubs that returned strings could produce garbage

Some Fortran stubs that returned strings did not properly use FIXRETURNCHAR() to blank out the end of the Fortran string. Thus the Fortran string would contain "garbage".

Fix warnings from gfortran 6.1 (OS X, Homebrew build)

gfortran 6.1 seems to include -Wconversion in -Wall. When configuring
with 64bit indices, the compiler emit warnings about conversions from
INTEGER(8) to REAL(4). Use REAL() intrinsic to silence the warnings.

sys: int64_t shoud use PRId64 - and not '%ld'. Also add PetscInt64_FMT and PetscInt_FMT to better manage this

replace uses of PetscMalloc() with PetscNew() or PetscMalloc1() where appropriate

Add test for -draw_ports options, remove unneeded multiple mallocs()

- convert test to use MPI - this way externalpacakge [MATLAB, MATLAB_ENGINE] tests are also run
- enable tests for MATLAB and MATLAB_ENGINE
- enable --with-matlabengine-lib option
- fix regression.py to use packages.PACKAGE - so that 'MATLAB_ENGINE' is used in TEST_RUNS - not 'MATLABENGINE'
- Fix MEX calls to use
- GCC - as version check is done in this compiler
- LDFLAGS - as -lgcov is listed here.

Merge branch 'tisaac/ts-ex11-amr'

We now have an example (ts/examples/tutorials/ex11.c) where we can
use either DMPlex or DMP4est to handle adaptivity when time stepping.
We have tried to minimize the amount of code that is specialized to the
different DMs, and in the future more work can be done to improve this
interface.

* tisaac/ts-ex11-amr: (62 commits)
DMP4est: type fix
Plex: Fixes for analyzer
DMP4est: update snes ex12 regressions
DMPlex: fix parent/child interpolation with numFields > 0
DMP4est: also compute anyChange for uniformly refined/coarsened meshes
TS ex11: fix command line for AMR without computed gradients
TS ex11: remove gradient reconstruction from adaptivity requirements
DMPlexTree: some compilers want this var initialized
Plex: Changed Get/RestoreFaceFields() and Get/RestoreFaceGeometry() to return the number of active faces - This fixes a long-standing bad access in FV, although the values were never actually used.
DMPlexTS: removed unused variables
DMPlex/DMP4est: small fixes for next warnings and errors
SNES ex36 and ex52: These do not work anymore
DMPforestGetTransferSF_Point(): try to match parents
PetscViewerHDF5: destroy old file data if setting new filename
DMPlex + FV: remove leaky references in projection functions
Plex: Fixed incredibly stupid bug in Jacobian computation
PetscViewer HDF5: added get name method
DMPlexTree: do not skip out of child matrix loops early
PetscFV: correct field offsets when limiting gradients
DMP4estTree: ignore negative values when getting/setting vector values for transfer

Fixed a variety of issues related to iOS builds

Some developers did not properly use relative paths for private include files
file that is not normally compiled had errors due to outdated API in it (why is it compiled with iOS?)
some iOS build scripts had outdated paths for various items
iSO version of makeall implicitly assumed PETSC_DIR had been set (OSX version previously fixed by Satish Balay)
