- Buffer deallocation (+IOCTL)
- Buffer reallocation
- Private dmabuf user list and accessor

There are possible value truncations when mixing types of different
width, e.g. s32 (int), u32, u64. This patch attempts to address
such issues in two ways:
1) Manually find and fix error-prone mixing.
2) Prevent creating a handle from an exuberantly large size.

The maximum selected size is set to maximum of system memory. This
is expected to be small enough that the number of pages fits even
in s32. This should offer some future protection in case nvmap starts
mixing int and u64 again.
