Second 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.
