Mr. Hong Zhang developed the petsc4py interface and examples.
Hansol Suh provided extensive help with updating the code to the latest PETSc coding guidelines and APIs, some documentation development, getting documentation to build correctly, getting new tests into the test harness, and numerous big fixes plus minor changes.
Barry Smith provided extensive feedback and code to get the Fortran interfaces and documentation build working.
Toby Isaac provided a fix to prevent breakage with complex-arithmetic builds.
Satish Balay provided important help with fixing builds.

Minor cleanup of Fortran binding stuff to simplify future maintainance

There is no distinction between F90 and non-F90 code so combine ftn-custom and f90-custom directories and fortranimpl.h and f90impl.h files. Also move uses of f90 to ftn when simple

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
