Lead to crash with python-dbg:

  python-dbg: ../Modules/gcmodule.c:366: visit_decref: Assertion 'gc->gc.gc_refs != 0' failed

Minor cleanup of a couple of examples

- fixed wrong references (The file on the left (right) -> actual file name)
- divided an example snippet of three files into separate files

Fixed indentation of a code example

Fixed a code example which had been indented with 2 spaces.

changed file order in Sharing C Functions example

This order looks more logical, easier to read.
