- Change the vm_mmap() function to accept an objtype_t parameter specifying

  the type of object represented by the handle argument.
- Allow vm_mmap() to map device memory via cdev objects in addition to
  vnodes and anonymous memory.  Note that mmaping a cdev directly does not
  currently perform any MAC checks like mapping a vnode does.
- Unbreak the DRM getbufs ioctl by having it call vm_mmap() directly on the
  cdev the ioctl is acting on rather than trying to find a suitable vnode
  to map from.
