Refactor the ioctl API and documentation

 * Split `ioctl!` into separate macros. This makes documentation easier to read.
 * For every `ioctl_*!` macro include a description of the macro arguments as, the
   function prototype for the generated wrapper function, and an example if we have one.
 * Expose `request_code_*!` in the documentation to make the `ioctl_*_bad` macros easier to use.
 * Reorganize the file hierarchy to be simpler
