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.

Python implementation for receiving and decoding debug-stream records
from debug window slot transportation. Opens SOF debugfs file
"debug_stream" reads and decodes the records from the circular buffer
documented in soc_debug_window_slot.h. This initial version only knows
of DEBUG_STREAM_RECORD_ID_THREAD_INFO records.
