In the long term, a lot of this package should be removed in favor of the
golang.org/x/image/math/f32 package. The latter is the common location for
matrix types shared across graphics libraries. For example, the
golang.org/x/image/draw package refers to golang.org/x/image/math/f64.

This does not break the dependency on the app package's AndroidContext
for loading assets on android. A potential answer for gobind-based
apps: add a SetAndroidContext method to app.Context. But I'll explore
that separately after the long weekend.

Historically, the app package implemented Go runtime initialization.
This was convoluted, so the package was used both by all-Go apps
(currently based on Android's NativeActivity) and bind-based apps.
With Go 1.5 we have -buildmode=c-shared, which does a lot of the work
of the old app package. That code was removed a while back, but both
all-Go and gobind-based apps still used package app. The intermingled
initialization processes led to some strange states.
This CL separates gobind-based apps completely from the app package.
As part of that users are now expected to use System.loadLibrary
themselves. (A future CL may want to make the loadLibrary call part
of the .aar generated by gomobile bind.)
Delete the libhello example, which has been replaced by gomobile bind,
which could do with its own example at some point. Also delete the
libhellojni example, which now has nothing to do with the x/mobile
repository.

This change will break Darwin. I have only built and tested this on
desktop linux and Android linux. A follow-up CL will fix Darwin.
Currently, OpenGL gets its own thread, and UI C code (e.g. the Android
event loop, or the X11 event loop) gets its own thread. This relies on
multiple system-provided UI-related C libraries working nicely together,
even when running on different threads. Keeping all the C code on the
one thread seems more sound.
As side-effects:
- In package app/debug, DrawFPS now takes an explicit Config.
- In package app, some callbacks now take an explicit Config.
- In package exp/sprite, Render now takes an explicit Config.
- In package event, there are new events (Config, Draw, Lifecycle),
and an event filter mechanism to replace multiple app Callbacks.
- In package geom, the deprecated Width, Height and PixelsPerPt global
variables were removed in favor of an event.Config that is
explicitly passed around (and does not require mutex-locking).
Converting a geom.Pt to pixels now requires passing a pixelsPerPt.
- In package gl, the Do, Start and Stop functions are removed, as well
as the need to call Start in its own goroutine. There is no longer a
separate GL thread. Instead, package app explicitly performs any GL
work (gl.DoWork) when some is available (gl.WorkAvailable).
- In package gl/glutil, Image.Draw now takes an explicit Config.
Callbacks are no longer executed on 'the UI thread'.
Changing the app programming model from callbacks to events (since a
channel of events works with select) will be a follow-up change.
