Normal map() should operate as before, and map_range()/map_flush() should
give correct results but lacking any performance difference from map().
Nothing exiting being done here yet, but the interface is a good start.
drm_handle_t is defined to be a u32 on linux and a u64 on everything
else. This addresses an issue on FreeBSD amd64 where the map offsets
may be greater than 32bits. When the handle is cast to 32bit, mmap
cannot match the requested map and causes X to crash.
This should be a NOOP on linux since drm_handle_t is always 32bit.

nouveau_notifier.c had two places where void* was used in arithmetic,
fixed by using char*.
nouveau_dma_wait(), nouveau_notifier_wait_status() and
nouveau_resource_alloc() had signed/unsigned comparison warnings, fixed
by changing the function parameter into an unsigned type.
