The PyArena type is not part of the limited API, so these headers
shouldn't be part of it either.

Unicode has grown since Python first gained support for it,
when Unicode itself was still rather new.

This pair of test cases was added in commit 6a20ee7d back in 2000,
and they haven't needed to change much since then.  But do change
them to look beyond the Basic Multilingual Plane (range(0x10000))
and cover all 17 planes of Unicode's final form.

This adds about 5 seconds to the test suite's runtime.  Mark the
tests as CPU-using accordingly.

Now the fields have names!  Much easier to keep straight as a
reader than the elements of an 18-tuple.

Runs about 10-15% slower: from 10.8s to 12.3s, on my laptop.
Fortunately that's perfectly fine for this maintenance script.

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.

We saw vulnerability warning description (including zip bomb) in Doc/library/xml.rst file.
This gave us the idea of documentation improvement. 

So, we moved a little bit forward :P
And the doc patch can be found (pr).

Before, running deactivate from a bash shell configured to treat undefined variables as errors (`set -u`) would produce a warning:

``` 
$ python3 -m venv test
$ source test/bin/activate
(test) $ deactivate
-bash: $1: unbound variable
```
