* Fix a deadlock in the free space allocator due to the AG-walking
algorithm forgetting to follow AG-order locking rules.
* Make the inode allocator prefer existing free inodes instead of
failing to allocate new inode chunks when free space is low.
* Set minleft correctly when setting allocator parameters for bmap
changes.
* Fix uninitialized variable access in the getfsmap code.
* Make a distinction between active and passive per-AG structure
references. For now, active references are taken to perform some
work in an AG on behalf of a high level operation; passive references
are used by lower level code to finish operations started by other
threads. Eventually this will become part of online shrink.
* Split out all the different allocator strategies into separate
functions to move us away from design antipattern of filling out a
huge structure for various differentish things and issuing a single
function multiplexing call.
* Various cleanups in the filestreams allocator code, which we might
very well want to deprecate instead of continuing.
* Fix a bug with the agi rotor code that was introduced earlier in this
series.

"This contains a fix for a deadlock in the allocator. It continues the
slow march towards being able to offline AGs, and it refactors the
interface to the xfs allocator to be less indirection happy.
