x11/gl is not thread-safe, so all x11/gl related API should be called
from one thread. There's already a dedicated thread for GL calls, so
move all x11 API calls to GL thread using gl.Do(...)

- Fix hangs on linux/x11. x11-related code remains outdated since
068a51c19, which seperates GL calls to dedicated thread. Update x11
code to work with GL thread.
- Fix bug on coordinate system. x11 has same coordinate system with
android, (0,0) on top-left.

Config provides a way to concurrently access Width and Height.
Register provides a way for packages to run code on app state change
without plumbing changes all the way to the process main function.
This is motivated by gl/glutil.Image which needs to rebuild its
textures on start/stop and can be deeply nested.
(See golang.org/cl/9707 for the followup.)
Tested manually on android and darwin/amd64. Doing this kind makes it
clear any CL modifying this code needs a lot of manual testing right
now, so some kind of trybot support is something I'm going to
prioritise.

An example of how to handle multiple concurrent touches using this design:
var touched = map[event.TouchSequenceID]*Widget{}
func touch(t event.Touch) {
if t.Type == event.TouchStart {
if w := widgetAt(t.Loc); w != nil {
touched[t.ID] = w
}
}
if w, ok := touched[t.ID]; ok {
// move/scroll widget, etc
}
if t.Type == event.TouchEnd {
delete(touched, t.ID)
}
}
