epriestley 2447d9bdf2 Begin improving modularity of IndexEngine, add locks ... Summary: Ref T9890. Ref T9979. Several adjacent goals: - The `SearchEngine` vs `ApplicationSearchEngine` thing is really confusing. There are also a bunch of confusing class names and class relationships within the fulltext indexing. I want to rename these classes to be more standard (`IndexEngine`, `IndexEngineExtension`, etc). Rename `SearchIndexer` to `IndexEngine`. A future change will rename `SearchEngine`. - Add the index locks described in T9890. - Structure things a little more normally so future diffs can do the "EngineExtension" thing more cleanly. Test Plan: Indexing: - Renamed a task to have a unique word in the title. - Ran `bin/search index Txxx`. - Searched for unique word. - Found task. Locking: - Added a `sleep(10)` after the `lock()` call. - Ran `bin/search index Txxx` in two windows. - Saw first one lock, sleep 10 seconds, index. - Saw second one give up temporarily after failing to grab the lock.
