Merge branch 'barry/update-blaslapack-support-download-batch'

Update BlasLapack.py to full use package class; support --download-xxxblaslapack in batch mode

Reported-by: Mark Adams <mfadams@lbl.gov>
Thanks-to: Satish Balay <balay@mcs.anl.gov>

Merge branch 'balay/add-prefix-test'

Move PetscHeap interface into petscsys.h so it is public so can be used directly in test examples

This allows src/mat/examples/tests/ex29.c to run in a prefix install

Merge branch 'barry/minor-cleanup'

remove PETSC_NULL from moab interface. Add definition of PETSC_NULL back in since external packages use it.

Reported-by: nightly tests

Minor cleanup, remove some outdated code, remove unneeded constructs, improve manual pages slightly, add missing test case

Time: 2.5 hours

Merge branch 'barry/remove-funct'

Merge branch 'barry/half-precision'

Remove the use and definition of __FUNCT__ throughout the code

Since all modern C/C++ compilers provide this functionality we no longer need to provide it manually in PETSc

Updated and simplified Fortran interface

Reduced from 4 distinct approaches to using PETSc from Fortran to 1
No more .h90 files (Fortran 90 functionality is now always available)
Parameters and function prototypes are now provide through Fortran modules, not includes;
only #define are provided in the petscXXXdef.h files
PETSc objects can be declared as either type(tXXX) or XXX. For example type(tVec) or Vec
Moved now private Fortran include files out of public include directory since uses don't use them;
they are only used to generate the Fortran modules
Easier to support and test; we can now easily add more function prototypes
Also had to rework generation of manual pages to consistently use MANSEC and SUBMANSEC
since these variables also handle how the Fortran modules are generated.

added PetscTellMyCell() since TextBelt appears to no longer send out the SMS

There are many such (for pay) services out there, I just picked one with a very simple, well documented RESTful
interface

added PetscTellMyCell() since TextBelt appears to no longer send out the SMS

There are many such (for pay) services out there, I just picked one with a very simple, well documented RESTful
interface and 10 free SMS so testing would be free.

Merge branch 'master' into tisaac/dmplex-feature-real-to-ref

I need updated PetscFE interfaces in what I'm going to do

* master: (603 commits)
parmetis: fix typo in testsuite
Added PETSC_HAVE_ATTRIBUTEALIGNED flag to makefile
PCSetUp_SVD() used incorrect matrix for matrix size in parallel, also need to skip LAPACK call if matrix size is zero
strumpack: update to latest version 1.0.4
Remove valgrind warning about MPI_Allreduce() with uninitialized data
sed for test output that has atol convergence with quad precision
updated ex1_nest tests
fixed incorrect key value
fix: bad merge a69d34a
test: move runex78 to TESTEXAMPLES_C_NOTSINGLE
build: fix warnings
sys: update test to produce same result - irrespective of debug/opt build - and presence of ~/.petscrc
sys: src/sys/examples/tests/ex30.c -> src/sys/examples/tests/ex32.c to avoid conflict in master
Sed output, since quad precision reduces below atol on these tests
remove automatically generated matrix names from test output files since can be different
Fixes for MatMPIXXXSetPreallocation(), they were not reentrant, since they kept the information used for matrix-vector products
GAMG: fix PCView_GAMG() format - and update output/ex56_0.out
superlu_dist: 64-bit-indices fix https://github.com/xiaoyeli/superlu_dist/issues/4
Add SNESSetDivergenceTolerance / -snes_divergence_tolerance.

Merge branch 'stefano_zampini/feature-convert-matnest-matis' into stefano_zampini/feature-pcbddc-saddlepoint

I have to merge it here, since there's an API addition for MatIS in stefano_zampini/feature-pcbddc-saddlepoint
that prevents me to smoothly merge stefano_zampini/feature-convert-matnest-matis into next.

This will also facilitate merging stefano_zampini/feature-pcbddc-saddlepoint into master
