[RFC PATCH v4 0/1] Add decoding of general DRM ioctl

[Zhibin Li]

In this patch I simply copy the libdrm headers into strace to get rid of
all those #ifdefs around drm ioctl constants. And there are still some
unfinished work. -v option is not added and I will try to discuss this
with you all later. I haven't incorporated esyr's print_local_array
since I'm not sure if I should rebase this commit and send them
together. drm_noop ioctls need to be tracked back to see if they worth
decoding. I might miss some thing here and comments are appreciated.

Changes in V4: 
 - Bundle the latest libdrm headers into strace so no need to check
   those #ifdefs now (any copyright statement needed?).
 - Factor out the common comma printing into ioctl_drm().
 - All #includes moved to the beginning.
 - Use the correct PRINT_FIELD_* macros.
 - Add a PRINT_FIELD_DRM_CRTC_ID macro for printing drm crtc_id fields
   since it's common in drm code. It's just a wrapper of PRINT_FIELD_U.
 - Print all pointers to arrays using print_array and provide
   corresponding callback printing functions.
 - Make all those missing R/W fields in place.
 - Those missing flags are added, too.
 - Add print_uint16_array_member().
 - Add a macro for wrapping !syserror && !umove.
 - Add #sorted and #value_indexed to xlat files.
