Marco Casaroli b695ec057f system/xipfs: Add a command to compact a xipfs volume and report it. 
xipfs has a defragmentation ioctl and no way to reach it from a shell.  The
only caller was a demo in examples/nxflatxip, which built its own block map
to show what compaction had done.

  xipfs [-n] [-t <ms>] [<mountpoint>]

-n surveys and reports without moving anything: where each file sits, a map
of the volume, and how much of the free space a single allocation can reach.
That last number is the one a caller facing -ENOSPC actually wants; at 0%
the largest possible file already fits however scattered the map looks.

The compaction is asked for through a descriptor for the mountpoint
directory, so no file inside the volume is open while it runs and a single
pass can reach every extent.

The walk descends into the directories xipfs synthesises from names, and
reports each file by its path relative to the mount, so a volume that uses
them is described in full rather than down to its first level.

Block totals come from statfs rather than XIPFSIOC_EXTENTINFO, because that
one does name a file and an empty volume has none, yet its geometry is still
worth reporting.
