Subject: [PATCH] docs/glossary: Elaborate on possible MicroPython port
 differences.

State that this doc describes generic, "core" MicroPython functionality,
any particular port may diverge in both directions, by both omitting
some functionality, and adding more, both cases described outside the
generic documentation.

+        "port" to that system. Different ports may have widely different
