pipeline: rpi: Add RequiresMmap flag to RPi::Stream
Add a new RequiresMmap flag to the RPi::Stream class indicating that buffers handled by the stream must be mmapped after allocation and cached internally. Add a new member function getBuffer(id) which can be used to obtain the mapped buffers for a given buffer id. Add a new member function acquireBuffer() which can be used to obtain any mapped buffer that has not already been acquired by the caller. As a drive-by, add the <algorithm> header to rpi_stream.cpp as it is needed for the std::find_if() function.
