Show Dalvik stack trace if an exception happens at draw time
External bug: http://code.google.com/p/android/issues/detail?id=49379

Drawing was previously wrapped in a try/finally block which was silently
swallowing user code exceptions. For instance, if a View throws a
NullPointerException in its onDraw() method, the previous implementation
would silently crash in native code.

This change extracts the section that builds display lists into a new
method that does not contain any try/finally block.

In addition, this change logs any exception thrown while drawing
display lists.
