HAMMER 24/many: Clean up edge cases

Hammer now survives many cpdup/rm-rf loops with recovery forced on.

* Fix an edge case with historical lookups.  When pushing down through a
  spike an exact match on a SPIKE_END element is no guarantee of success,
  so check for and flag the delete boundary in that case.

* Delay physical cluster deletions (marking the cluster as free in the
  Volume's A-list) until the last ref on the cluster goes away.

* Fix a race between cluster deletion, filesystem sync, and recovery.
  Do not attempt to recover a cluster marked as undergoing deletion.

* Enable cluster recovery by default.  It is still fairly primitive but
  it should work well enough to put the filesystem in a working state
  once the remaining debug shims are removed.

* Clean up sequencing of io->modified to ensure that clusters are properly
  closed during normal operation.  Recovery operations should only occur
  when encountering an open cluster after a crash.

* Do not open a cluster or create a cluster->buffer dependancy when only
  updating the mtime or atime of an inode.

* In the hammer_sync_*() procedures, ref the volume/cluster prior to
  scanning its RB tree, use hammer_ref() instead of hammer_ref_*() to
  avoid unnecessary loads.  This also fixes a stale pointer bug in the
  same code.

* Remove the stack recursion in btree_remove().  btree_remove() is now able
  to clean up empty nodes going all the way up the tree (at least until it
  hits a deadlock, which is not yet handled).

* Fix primary filesystem statistics (they were getting off because
  whole clusters were being deleted without bothering to free up internal
  on-disk structures).

* Fix a minor bug in the cluster's stat_records tracking field.  'df' no
  longer shows a bleeding capacity.  Statistics will still get off due
  to crashes and such (the balancer will probably have to deal with that).

* Add more assertions.  How do you debug complex code?  You assert that
  everything is in its proper state, everywhere you can.

Warning: filesystem structures have changed, recompile newfs_hammer too.

  flag the need for an iteration anywhere the edge case is hit as we
  recurse down, not just on the terminal B-Tree node.

* Get rid of the kludge record buffer bitmap in the cluster header.  Augment
  the A-List recovery and scanning code to locate record buffers.   This
  required adding some unfortunate complexity to the A-list search and
  recovery routines due to the fact that we ran out of bit codes and
  couldn't represent an all-free/initialized AND an all-free/uninitialized

* Go back to making the SPIKE_END elements range-inclusive instead of
  range-exclusive.  It turns out that making them range-exclusive caused
  a few too many collisions with adjacent records in the B-Tree.

* Excellent progress on the recovery code.  It still has numerous issues
  (there are lots of recovery cases I still have to implement), but
  it survives much longer now.  Add a sysctl to disable/enable/force
  cluster recovery (default disabled, since its still buggy).

* When creating a spike be sure to properly assign the cluster record's

* When removing a spike be sure to also free the related cluster record.

* Spike code progress.  Implement the last case it couldn't handle (spiking
  a spike) and add a very simple starter heuristic which generates a
  better spike topology (doesn't create long chains of end-range spikes).

* Add a huge number of new assertions to ease the tracking down of bugs.

* Address some IO sequencing issues that could result in io.modified
  getting prematurely cleared.  io.modified can only be cleared on write
  initiation on the last ref to a HAMMER structure.

* Add a hack to pre-reserve enough B-Tree buffers to guarantee the recovery
  code can regenerate the B-Tree without having to pack it.  This ultimately
  needs to be fixed (the recovery code really needs to pack the tree).
