Commit Message

Introduce DropPrefix API in Badger (#715)

This API would allow Badger to completely get rid of the given prefix, P. It does this by:

1. Flushing memtables to disk (skipping over the keys with P).
2. Doing normal compaction from L0 -> L1 (skipping keys with P).
3. Doing same level compaction on all the rest of the levels, picking tables which might have the prefix and rewriting them to new tables (again, skipping keys with P).

Before starting, all the writes are paused, the usual bits which apply to `DropAll` apply here as well.

Note: This PR has a breaking change for the Logger interface. It adds a Debugf API.

Changes:

* Working drop prefix
* Make the drop prefix more robust. Add a new Debugf API for logging.
* Add parallel tests for DropPrefix
* Avoid a test failure due to removing p dir.
* Only test DropPrefix in DropPrefix test.
* Address Martin's comments
