Also clean up the Choreographer so that it doesn't directly extend
Handler and so that it doesn't schedule animation or drawing unless
there are listeners or callbacks attached.

The synchronization barrier enables selectively blocking
execution of synchronous messages until the barrier is released.
Asynchronous messages may continue running in the meantime.
The barrier is intended to be used to implement more sophisticated
scheduling policies related to view hierarchy traversals. While
traversals are pending, most messages posted to the message queue
must be held up. This is to satisfy the invariant that traversals
will occur before subsequently posted messages are handled.
The exception to this rule are "asynchronous" messages that represent
external events or interrupts that come from other components such
as VSYNC pulses, input events or sensor events. Because these messages
are typically delivered at arbitrary times, they are independent of
traversals or other typical synchronization boundaries.
Messages can now be flagged as asynchronous to indicate that they
are weakly ordered.

The framework tries to have a focused view all the time. For
that purpose when a view's focus is cleared the focus is given
to the first focusable found from the top. The implementation
of this behavior was causing the following issues:
1. If the fist focusable View tries to clear its focus it
was getting focus but the onFocusChange callbacks were not
properly invoked. Specifically, the onFocusChange for
gaining focus was called first and then the same
callback for clearing focus. Note that the callback
for clearing focus is called when the View is already
focused.
2. If not the first focusable View tries to clear focus,
the focus is given to another one but the callback
for getting focus was called before the one for clearing,
so client code may be mislead that there is more than
one focused view at a time.
3. (Nit) The implementaion of clearFocus and unFocus in ViewGroup
was calling the super implementaion when there is a
focused child. Since there could be only one focused View,
having a focused child means that the group is not focused
and the call to the super implementation is not needed.
4. Added unit tests that verify the correct behavior, i.e.
the focus of the first focused view cannot be cleared
which means that no focus change callbacks are invoked.
The callbacks should be called in expected order.
Now the view focus clear precedes the view focus gain
callback. However, in between is invoked the global
focus change callback with the correct values. We may
want to call that one after the View callbacks. If
needed we can revisit this.

this simplify our EGL wrapper implementation a lot.
This wrapping is no longer needed now that we can only
support a single underlaying EGL implementation.

This patch updates the trace information for all glUniform*() calls
to have the right data (the actual uniforms that are passed).
In addition, as soon as a program is linked, information regarding
all the active attributes and uniforms is passed on to the debugger.
