[PATCH] rio driver rework continued #2

First large chunk of code cleanup.  The split between this and #3 and #4 is
fairly arbitary and due to the message length limit on the list.  These
patches continue the process of ripping out macros and typedefs while cleaning
up lots of 32bit assumptions.  Several inlines for compatibility also get
removed and that causes a lot of noise.
