This is based on the OSDMap::print_tree(), but is a bit simpler because
we do not have up/down information at this level.

For firstn mode, if we fail to make a valid placement choice, we just
continue and return a short result to the caller. For indep mode, however,
we need to make the position stable, and return an undefined value on
failed placements to avoid shifting later results to the left.

This is only present to size the temporary scratch arrays that we put on
the stack. Let the caller allocate them as they wish and remove the
limitation.

These are supported as of kernel version v3.9:
- chooseleaf_descend_once was added in 1604f48
- others were added in 546f04e
And of course these are supported by bobtail and later.

Set the tunables to the 'default' values on create.
Default to the legacy values when we decode, so that an old map without
values defined gets legacy values.

4d140a71a1 refactored this and
introduced a bug. peek_meta() was accidentally reading into magic,
then replacing magic with val, which was always the empty string,
resulting in the osd always failing to start due to 'mismatched'
magic values.

One use noted that they have a 'pdu' type in their type hierarchy that
typically spans multiple racks. Others are known to use the 'pod'
terminology; add that to. And I can imagine 'region' above datacenter.
Factor this into a helper to make things a bit less fragile.

A chassis is usually bigger than a host but smaller than a rack. This will
be useful for a broad class of modern hardware that sticks multiple hosts
in the same chassis (in sleds, or on cards, or blades, or whatever).

Move these from the OSD. Use a generic implementation in ObjectStore that
hopefully all backends can share (so that it can remain in sync with the
start/stop scripts, ceph-disk, and other orchestration machinery).
