Add automatic generated fortran support for setting and returning contexts

Major cleanup of the code for setting and returning application (previously called user) contexts
- PetscCtx ctx is now the standard for passing in contexts
- PetscCtxRt ctx is the standard for passing out contexts, including context destroy routines based on PetscCtxDestroyFn

Both of these are typedef to void*

Also removed most use of user and userctx for context arguments now consistently named ctx

Improved documentation on PetscCtx and PetscCtxRt and on how to use contexts (including getting them) from Fortran

Fix a race condition in PCMPISolve() when using Unix shared memory.

The 0th rank accesses the solution of the other rocesses before the other processes have finished updating the final solution locally. This cannot happen with the MPI communication based version because the communication is done with an MPI_Allgatherv() that blocks on the processes getting to that point before copying over the data.

Use PetscBool instead of PetscInt for setupcalled

PetscInt was used in some structs, but the underlying logic requires only Booleans. Also removed an unused variable and unified capitalization.

Fortran 90: fully embrace After 34 years!

- deprecate use of 'F90' in Fortran function names
- use Fortran pointers when appropriate
- the new Fortran API is not backward compatible with previous versions!
- also clean up inconsistent PETSc code detected by new Fortran generation tools
- drop use of bfort
- automatically generate all the Fortran PETSc objects, enums etc from the include files
- generate most of the Fortran interface definitions and functions from the source code
- simplify the number and organization of Fortran modules

Unifies all context destructors to have a form of PetscCtxDestroyFn == PetscErrorCode (*)(void **)

Changes the previous subset of destructor APIs that used PetscErrorCode (*)(void *) (mostly those that
used PetscContainer

- Now allows any context to be a PetscObject
- Will provide a cleaner mapping to bindings in other languages
- Simplifies the maintenance of PETSc source code; improves clarity

Not backward compatible, compiler warnings will tell users what functions need to be updated
