This is the vastly updated cx drvier from Roman Kurakin <rik@cronyx.ru> who has been patiently waiting for this update for sometime. The driver is mostly a rewrite from the version we have in the tree. While some similarities remain, losing the little history that the old driver has is not a big loss, and the re@ felt it was easier this way (less error prone). The userland parts of this update will be committed shortly. The driver is not connected to the build yet. I want to make sure I don't break any platform at any time, so I want to test that with these files in the tree before I continue (on the off chance I'm forgetting a file). I changed the DEBUG macro to CX_DEBUG from the code that was submitted (to not break when we go to building with opt_global.h after the release), as well adding $FreeBSD$.
