Add NextFile function to ScanCursor, which returns the first file after the cursor position.
Add a background span policy enforcer that scans the LSM to detect files violating compression policies and marks them for policy enforcement compaction (a new compaction type that will be introduced in a later commit). Currently disabled by default, this initial implementation scans at a rate of 1 file per second, and checks only for a violation on the compression settings in the span policy.
