c0cc46a2be scorch cleanup of the rootBolt of old snapshots
A new global variable, NumSnapshotsToKeep, represents the default
number of old snapshots that each scorch instance should maintain -- 0
is the default.  Apps that need rollback'ability may want to increase
this value in early initialization.

The Scorch.eligibleForRemoval field tracks epoches which are safe to
delete from the rootBolt.  The eligibleForRemoval is appended to
whenever the ref-count on an IndexSnapshot drops to 0.

On startup, eligibleForRemoval is also initialized with any older
epoch's found in the rootBolt.

The newly introduced Scorch.removeOldSnapshots() method is called on
every cycle of the persisterLoop(), where it maintains the
eligibleForRemoval slice to under a size defined by the
NumSnapshotsToKeep.

A future commit will remove actual storage files in order to match the
"source of truth" information found in the rootBolt.

398dcb19b3 scorch introducer uses the roaring.Or(x, y) API
Instead of cloning an input bitmap, the roaring.Or(x, y)
implementation fills a brand new result bitmap, which should be allow
for more efficient packing and memory utilization.
