lib/ioctl_wrappers: api doc

Browse Source 
Also some tiny polish to function interface:
- @caching in gem_set_tiling should be uint32_t to match the ioctl
  struct.
- s/size/length/ for gem_write/read.
- move gem_get_num_rings to the other ring feature helpers.

v2: Also demote gem_require_ring from static inline and move it, too.

v3: Also move gem_handle_to_libdrm_bo.
