Alan Somers d49b446bfb Add FIOBMAP2 ioctl ... This ioctl exposes VOP_BMAP information to userland. It can be used by programs like fragmentation analyzers and optimized cp implementations. But I'm using it to test fusefs's VOP_BMAP implementation. The "2" in the name distinguishes it from the similar but incompatible FIBMAP ioctls in NetBSD and Linux. FIOBMAP2 differs from FIBMAP in that it uses a 64-bit block number instead of 32-bit, and it also returns runp and runb.
