Package app contains some logic that we want to share with
gobind-based libraries. So move it to a new internal package
that both can import.
Long term the log changes should be in the standard library,
but the Go tree is currently frozen.
Fixesgolang/go#11630.

Before this change, func Hello() of mypkg package generated a function
GoMypkg_Hello to distinguish the prefix from the function name.
It seems the use of '_' is very rare in Objective-C though.
After this change, it generates GoMypkgHello.

The full set of event.LifecycleStages are now plumbed through.
More user control over the window, in particular it:
- takes focus correctly on start
- can now be closed and minimized
- can be hidden (allowing testing of LifecycleStageAlive)
Flickering during resize has been eliminated by triggering draws from
a second thread. This encouraged the introduction of a dedicated draw
loop in Go, which makes responsibility for GL calls a little more
like android/x11.

Ever since we moved to a bitmap font instead of using freetype, the backing
image's dimensions are 43x9, not 50x12, and we might as well match. For
example, the output will be exactly 43x9 pixels at 72DPI, or 86x18 pixels at
144DPI, etc.

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.

The Go toolchain used to require that we rebuild the compiler and
friends (the cgo command) when building a cgo-enabled cross compiler.
This meant that gomobile init used to invoke make.bash in a temporary
copy of the GOROOT. This works, but brings with it several
complications, including needing to use -toolexec when invoking the
go tool, finding a boostrap copy of Go 1.4, long initialization
times, and a variety of unusual failure modes.
Fortunately we don't need our own compiler any more. All that's
necessary is building the standard library for the cross-compilation
targets and making sure the right C compiler is used when calling
go build (as it always was). This means most of the initialization
process can be replaced with a carefully invoked 'go install std'.
While here, remove the source install instructions (most of it is
documented already, and the final step, choosing the right git
revision should be within the skills of anyone using pre-release
software.) Some other documentation is changing because it's been a
while since go generate was run.

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.

Move runtime.LockOSThread from the portable Main to the
platform-specific android main. For darwin, calling LockOSThread in
Main is too late, there has been enough time for the goroutine
calling it to jump off the initial OS thread. For darwin we call
LockOSThread from an init function, which the runtime keeps on the
first thread. For Android we call LockOSThread only to maintain the
thread-local storage for the GL context that is created later, so
it is safe to call it from func main.
Also remove TODOs about starting a gobind app on Android, which
will be simplified in a followup CL.
Tested on darwin/amd64 and android. Not tested on X11.

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.
