Change gioui.org/commit/0e70fbc1262920a69c60409285795b6bb8701b09
added a note that app.Window.Queue must only be used during the
processing of a FrameEvent. The change was added because a Gio
user took the existence of app.Window.Queue to mean it was always
available.
This change reduces the scope of window Queues by moving it from Window
to FrameEvent, and minimizes the risk of misuse by not offering
Window.Queue at all.
Note that the gioui.org/commit/a937a7653439333b8c6fc30c7a6039b717339766
change moved Window's Frame method (named Update) to FrameEvent for the
same reason.

For integrating with external window implementations (replacing
package app), access to the event router is required. Extract it
and put it into the new package router.
Router may belong in package io/event, but can't without introducing
import cycles.

Allows things like "ctrl-{" and ".".
All punctuation is returned as-is, e.g. "!" is "!", not "shift-1", and
"{" is "{", not "shift-[".
Also add the Enter key as a known key (fn-return on my Mac).

Function keys don't have a natural rune representation so switch
Event.Name to be a string to fit "F1"-"F12".

By returning the allocated data buffer, Ops can become an interface
in a future change without forcing operations to allocate.

Package app is the only package that depends on native libraries and
Cgo. Minimize its API, thereby minimizing Gio clients' dependency on
it. In the future, a headless, testing or remote "Window" should be
very easy to replace app.Window.

It wasn't used, and it's not clear that it is useful at all in its current
form. For example, a single control with multiple handler keys (say, one for
scrolling and one for clicking) will only receive priority Foremost for one of
them.

Packages that provide support for external events such as pointer, key and
system are only the beginning. Future packages are expected for clipboard
access, drag and drop, gps positions and so on.
To keep the number of top-level packages under control, move such I/O packages
to the new `io` directory.
The `system` package name was the previous solution to keeping the number of
top-level packages under control: I named it `system` instead of the narrower
`profile` because I expected to put all the less common events into it, turning
`system` into a "package util" smell.
With `io`, package system can be renamed to `profile`.
