Add the --file-layout (-f) option to zdb(8)
Displays the physical raidz block layout for a given file.
This leverages the internal vdev_raidz_map_alloc() function to find
the map of how the block data is laid out across the child disks.

The column entry for each row looks like:
+------------+
|  D2     43 |
|     6020da |
+------------+
representing here the logical data column 2 that is 43 sectors high
starting at sector 0x6020da.

With -H, the output is a list of disks, LBAs, and block counts,
given in 512 byte block values.
