bpo-38120: Fix DeprecationWarning in test_random for invalid type of arguments to random.seed. (GH-15987)

The >=, checking whether a module index was in already in the module-by-index list, needed to be strict.

Also, fold nested ifs into one and fix some bad spacing.

Summary: This mostly migrates Python-ast.c to PEP384 and removes all statics from the whole file. This modifies the generator itself that generates the Python-ast.c. It leaves in the usage of _PyObject_LookupAttr even though it's not fully PEP384 compatible (this could always be shimmed in by anyone who needs it).

The socket module now has the socket.send_fds() and socket.recv.fds() functions.

$ source test/bin/activate
(test) $ deactivate
-bash: $1: unbound variable
```
