forked from KolibriOS/kolibrios
New organization of irq buffer, now its ring buffer. Its faster about 4.5 times.
*Warning! its debug version which can have many bugs, because I cannot test it all. I tested byte's receive on little size of data. If you can test it on big data size, and word's receive - do it! :) git-svn-id: svn://kolibrios.org@759 a494cfbc-eb01-0410-851d-a64ba20cac60
