pipeline: raspberrypi: Repurpose RPi::Stream::reset()
The original use of RPi::Stream::reset() was to clear the external flag state and free/clear out the framebuffers for the stream. However, the latter is now done through PipelineHandlerRPi::configure(). Rework PipelineHandlerRPi::configure() to call RPi::Stream::setExternal() instead of RPi::Stream::reset() to achieve the same thing. Repurpose RPi::Stream::reset() to instead reset the state of the buffer handling logic, where all internally allocated buffers are put back into the queue of available buffers. As such, rename the function to RPi::Stream::resetbuffers(). This resetbuffers() is now called from PipelineHandlerRPi::start(), allowing the pipeline handler to correctly deal with start()/stop()/start() sequences and reusing the buffers allocated on the first start().
