Marcel Moolenaar 9af0c69a15 Remove debugging output. We should have tracing instead. 2015-07-26 16:40:51 +00:00
Marcel Moolenaar 4af242aad1 Implement busdma_md_unload() and busdma_sync(). 
While here:
1.  have the Python bindings contain constants for the space
    identifiers and the sync operation.
2.  change the segment iterators to return None when done,
    not ENXIO.
