KAMEZAWA Hiroyuki 4a3956c790 vfs: introduce FMODE_UNSIGNED_OFFSET for allowing negative f_pos 
Now, rw_verify_area() checsk f_pos is negative or not.  And if negative,
returns -EINVAL.

But, some special files as /dev/(k)mem and /proc/<pid>/mem etc..  has
negative offsets.  And we can't do any access via read/write to the
file(device).

So introduce FMODE_UNSIGNED_OFFSET to allow negative file offsets.
