Currently, to activate OpenGL tracing, an application has to be
start with --opengl-trace option (or have a debug prop set).
This CL adds support for tracing an application which may already
be running. This is implemented as follows:
- DDMS initiates a JDWP message to the VM indicating that
opengl traces be enabled.
- When that message is received, a flag is set that indicates
that tracing should be enabled.
- The trace flag is checked during every eglSwap() operation,
and if it finds that tracing should be active and it isn't,
then it starts the tracing component.
