Access debug slot directly using cavstool.py, by specifying the debug slot number where the debug_stream data is transferred. Adds one command line parameter for selecting the debug slot directly and adds an alternative mainloop for polling the slot through cavstool.py direct access. The commit also adds quite a few data consistency checks and error handling improvements as with the direct memory access its much more likely to get inconsistent data when the DSP is booting up, and code needs to be robust enough not to crash in such a situation. Also the logging messages about those checks failing has been lowered so that they are not too noisy. Signed-off-by: Jyri Sarha <jyri.sarha@linux.intel.com>
Add overlay to build debug_stream protocol over a debug window slot, make room for the slot, and send thread info data through it. Signed-off-by: Jyri Sarha <jyri.sarha@linux.intel.com>

The new cavstool.debug_slot_offset_by_type() opens an opportunity to improve debug_stream.py usability a bit. If the debugfs file is not found, then try to find the correct debug slot the correct slot using cavstool direct access and debug_slot_offset_by_type().
