Just wondering if this line shouldn't be inside the if as well, in the Apply function we will not set the allowed seeks anymore so doesn't seem like we should be decrementing them as well.

That's a good point, thanks for catching this! I agree with your assessment and will move the decrementing of allowed_seeks inside the if block.

Moved over the option to disable auto-compaction based on number of seeks. This is based on the two commits in leveldb-mcpe:
Second commit is a clean-up to get unit tests to pass.
