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.

Time: 57 hours

Merge branch 'master' into stefano_zampini/feature-pcbddc-saddlepoint

This is needed to deal with some changes in MatNullSpace from commit 9d2471e

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

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.
fixed unit read in Plex

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

rm white space; suggest puting your stuff in MatCreateMatrix_Network() into a subroutine DMCreateMatrix_Network_Nest();

DMNetwork: add indexing for vertices and edges, add suport for MATNEST

This is a re-work of pull request 557.

- d.o.f sections for vertices and edges are created with the routime
DMNetworkAssembleGraphStructures.

- DMNetwork can create a nested matrix using these structures. The user
can access the submatrices with routines DMNetworkGetEdgeOffset,
DMNetworkGetVertexOffset.

- Additional tests have been included.

Merge branch 'master' into barry/fix-successful-numerical-factorization-after-failure/master

The maint patch for the given problem cannot merge cleanly into next due to changes
in the same code in master (the introduction of MatFactorGetError()) therefor need
to merge in master and use the new construct before merging to next
