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.

Summary: Fixes T5991. If //all requested documents// failed to index, consider this a catastrophic failure and exit with an error code.
Test Plan:
- Ran `bin/search index --type TASK`, observed successful exit despite a small number of un-indexable documents.
- Ran `bin/search index PHID-TASK-xxx` for an invalid task, observed exception on exit after complete failure.
- Ran normal indexing through daemons.

Summary: Ref T6822. This method is only called from within the `PhabricatorWorker::executeTask()` and `PhabricatorWorker::scheduleTask()` methods.
Test Plan: `grep`ped for `->doWork`.

Summary:
Ref T3165. Builds a dedicated index for Conpherence to avoid scale/policy filtering concerns.
- This is pretty one-off but I think it's generally OK.
- There's no UI for it.
- `ConpherenceFulltextQuery` is very low-level. You would need to do another query on the PHIDs it returns to actually show anything to the user.
- The `previousTransactionPHID` is so you can load chat context efficiently. Specifically, if you want to show results like this:
> previous line of context
> **line of chat that matches the query**
> next line of context
...you can read the previous lines out of `previousTransactionPHID` directly, and the next lines by issuing one query with `WHERE previousTransactionPHID IN (...)`.
I'm not 100% sure this is useful, but it seemed like a reasonable thing to provide, since there's no way to query this efficiently otherwise and I figure a lot of chat might make way more sense with a couple of lines of context.
Test Plan:
- Indexed a thread manually (whole thing indexed).
- Indexed a thread by updating it (just the new comment indexed).
- Wrote a hacky test script and got reasonable-looking query results.

Summary: Fixes T3857. Earlier work made this trivial and just left product questions, which I've answered by requiring the daemons to run on reasonable installs.
Test Plan: Ran `bin/search index` and `bin/search index --background`. Observed indexes write in the former case and tasks queue in the latter case. Commented with a unique string on a revision and searched for it a moment later, got exactly one result (that revision), verifying that reindexing works correctly.
