When a window goes from the Minimized state to Windowed
as the user brings it back up, the internal state needs
to reflect that change and generate the corresponding
Config event.

Commit 11aec807b2 added a waiting flag to avoid
processing platform events recursively. However the flag was only true when the
window goroutine is blocked waiting for client events, so deferred window
functions such as Window.Option may still runs multiple times for recursive
events.
This change renames the flag to busy and sets it during the entire processing
of an event, including recursive events and deferred window functions.

The window modes are extended, following microsoft conventions.
We have Fullscreen, Overlapping, Maximized and Minimized.
These modes can be set via options when a new window is creates,
or modified later by calling helper functions like w.Maximize() and w.Center()
The window configuration is automatically updated when a user
modifies the window by dragging or clicking the icons on the window's title-bar,
minimizing or maximizing the window.
Any change, either by the user or the application will emit a ConfigChange event.
This is implemented and tested on Windows only.
API change. the app.Window methods Maximize and Center are replaced with similar
options. For example, to maximize a window use
w.Option(app.Maximized.Option())
Also, Maximize and Center implementations for X11 and macOS are left for a future
change.

This change causes modifier keys (Control, Shift, Alt, Super) to be sent
to the application as key.Event events. These will still continue to be
used as modifiers for other key and pointer events as they are today.
This commit also adds a minor cleanup to use constants for function
keys in the OS-specific keypress handling functions.

If the client calls, say, Window.Configure during a frame which in turn results
in a ConfigEvent, the program deadlocks. This change implements a queue of

OpenGL stores the current context in thread-local memory, but commit
4f5baa9a51 removed a runtime.LockOSThread from app.Window that ensured
the goroutine that drives the context stays on the operating thread that
has the context current. This change restores the thread lock.
As a bonus, this change makes the OpenGL contexts responsible for locking
the thread at MakeCurrent, thereby removing LockOSThread calls from GPU
backend-agnostic code.

Before this change, Window driver callbacks would all go through
channels to be processed by Window.run. However, Window.run may call
into the driver, which again may invoke a Window callback. These
re-entrant calls have been a source of deadlocks and subtle errors,
resulting in increasingly complex channel logic. This change eliminates
the goroutine split between Window and the driver, allowing callbacks
between Window and the driver without restrictions.
The goroutine split between Window and the driver is historical and
was meant to tame the complicated callback logic of drivers into a nice
for-select loop. However, the complexity isn't worth the gain, and there is
no concurrency concerns because there is always a 1:1 correspondance between
a driver goroutine and its Window object.

This change is to augment the X11 clipboard write behaviour.
When writing to the clipboard both the primary and clipboard
selections are published so that non-GIO applications that read
the primary selection (i.e. such as terminal emulators using
middle-mouse clicks) can read the data from a GIO app.

This change implements a Vulkan port for the two renderers, old and
compute. Run with GIORENDERER=forcecompute to test the compute renderer.
To shake out bugs faster, it is also made the default on systems that
support it. To disable Vulkan and force the use of OpenGL, use the
`novulkan` tag:
$ go run -tags novulkan gioui.org/example/kitchen
Don't forget to file an issue describing the issue that prompted the use
of the tag.

Unlike Raise, Close and other fire-and-forget methods on Window,
Config calls driverRun because it needs to wait for the result.
However, driverRun isn't guaranteed to block in all contexts.
This change avoids the synchronization dance altogether by removing the
Config method and introducing a ConfigEvent event. The event also makes
it clear when the configuration changes.
