Merge #15694: Link discussion of file objects to glossary entry.

This is analogous to the link for `flie objects` in the description of
'open' that exists in the 2.7 docs, and adds a similar link to the
io docs.

Overview
--------
The :mod:`io` module provides Python's main facilities for dealing for various
types of I/O. There are three main types of I/O: *text I/O*, *binary I/O*, *raw
I/O*. These are generic categories, and various backing stores can be used for
each of them. Concrete objects belonging to any of these categories will often
be called *streams*; another common term is *file-like objects*.

The :mod:`io` module provides Python's main facilities for dealing with various

categories is called a :term:`file object`. Other common terms are *stream*
and *file-like object*.
Independently of its category, each concrete stream object will also have
various capabilities: it can be read-only, write-only, or read-write. It can
