No deprecation, as these can't be properly deprecated anyways.
You can deprecate anything. It's just a matter of writing an entry into the deprecations list. What you cannot do here is warn the user when he uses the deprecated variables (well at least not before 3.7).
I may be overly catious but this seems like some people will have used it. So I'm in favor of a proper depreaction.
- Add a deprecation note. We're at least formally safe. People could have read the deprecation notes before switching to a new version.
- For Py3.7+ use module-level getattr to warn.

"Use the native Qt modifiers instead."

Restored with deprecation notice. Let's leave module-level getattr until we set up some generic helpers for them (I had a PR somewhere demo'ing how to do that...). |

- Replace MODIFIER_KEYS by a simpler private table that doesn't include
the names used by Matplotlib ("super"/"alt"/...), instead just get
these names from SPECIAL_KEYS (this avoids having to also update
_MODIFIER_KEYS for osx, where we use different names).
- Deprecate the globals SUPER, ALT, CTLR, SHIFT which were just indices
into MODIFIER_KEYS but otherwise meaningless.
- Invert the order of _MODIFIERS_KEYS to avoid having to do a
`reverse()` later in the code.
- Get max_unicode value from Python's sys module.
