    drm cleanup 14/x: Slightly rewrite drm debug subsystem.
    
    Changes:
      * Bring back kernel options handling through opt_drm.h that
        got lost in: ba55f2f542af67c1331fd80f611891b0a29f57bc
      * Explicitly disable DRM_LINUX option, breaks LINT64
      * Add some DragonFly specific debug categories to ease up
        the debugging, some DRM_DEBUG prints are quite noisy
      * By default don't include PID number, hard on diffs
      * Handle ioctl debug prints with separate debug bits
      * Implement DRM_ERROR_RATELIMITED that uses krateprintf()
      * Implement and use drm_err() and drm_ut_debug_printk()
        note: that current implementation might lead to more
        garbled text on a very frequent writes by several cpus
    
    After this cleanup drm modules shrink a bit in size:
     [rw at _ drm]$ size z*/*.ko
        text    data     bss     dec     hex filename
