I was also wondering if it makes sense to rename these subclasses as `PhabricatorXSearchField` rather than `PhabricatorSearchXField` (as per T5655), but wasn't really sure if these objects are meant to be search-fields, or just fields belonging to the #search application.

Summary:
Ref T8637. This does nothing interesting, just has empty scaffolding for a bulk job queue.
Basic idea is that when you do something like a batch edit in Maniphest, we:
- Create a BulkJob with all the details.
- Queue a worker to start the job.
- Send you to a progress bar page for the job.
In the background:
- The "start job" worker creates a ton of Task objects, then queues worker tasks to do the work.
In the foreground:
- Fancy ajax animates the progress bar and it goes wooosh.
In general:
- Big jobs actually work.
- Jobs get logged.
- You can monitor jobs.
- Terrible junk like T8637 should be much harder to write and much easier to catch and diagnose.

No interesting code/beahavior yet. Clean `storage adjust`.

Summary:
Ref T4100. Ref T5595.
To support a unified "Projects:" query across all applications, a future diff is going to add a set of "Edge Logic" capabilities to `PolicyAwareQuery` which write the required SELECT, JOIN, WHERE, HAVING and GROUP clauses for you.
With the addition of "Edge Logic", we'll have three systems which may need to build components of query claues: ordering/paging, customfields/applicationsearch, and edge logic.
For most clauses, queries don't currently call into the parent explicitly to get default components. I want to move more query construction logic up the class tree so it can be shared.
For most methods, this isn't a problem, but many subclasses define a `buildWhereClause()`. Make all such definitions protected and consistent.
This causes no behavioral changes.

Summary:
Right now, taskmasters on empty queues sleep for 30 seconds. With a default setup (4 taskmasters), this averages out to 7.5 seconds between the time you do anything that queues something and the time that the taskmasters start work on it.
On instances, which currently launch a smaller number of taskmasters, this wait is even longer.
Instead, sleep for the number of seconds that there are taskmasters, with a random offset. This makes the average wait to start a task from an empty queue 1 second, and the average maximum load of an empty queue also one query per second.
On loaded instances this doesn't matter, but this should dramatically improve behavior for less-loaded instances without any real tradeoffs.
Test Plan: Started several taskmasters, saw them jitter out of sync and then use short sleeps to give an empty queue about a 1s delay.

Summary:
Ref T6881. Hopefully, this is the hard part.
This adds a new daemon (the "trigger" daemon) which processes triggers, schedules them, and then executes them at the scheduled time. The design is a little complicated, but has these goals:
- High resistance to race conditions: only the application writes to the trigger table; only the daemon writes to the event table. We won't lose events if someone saves a meeting at the same time as we're sending a reminder out for it.
- Execution guarantees: scheduled events are guaranteed to execute exactly once.
- Support for arbitrarily large queues: the daemon will make progress even if there are millions of triggers in queue. The cost to update the queue is proportional to the number of changes in it; the cost to process the queue is proportional to the number of events to execute.
- Relatively good observability: you can monitor the state of the trigger queue reasonably well from the web UI.
- Modular Infrastructure: this is a very low-level construct that Calendar, Phortune, etc., should be able to build on top of.
It doesn't have this stuff yet:
- Not very robust to bad actions: a misbehaving trigger can stop the queue fairly easily. This is OK for now since we aren't planning to make it part of any other applications for a while. We do still get execute-exaclty-once, but it might not happen for a long time (until someone goes and fixes the queue), when we could theoretically continue executing other events.
- Doesn't start automatically: normal users don't need to run this thing yet so I'm not starting it by default.
- Not super well tested: I've vetted the basics but haven't run real workloads through this yet.
- No sophisticated tooling: I added some basic stuff but it's missing some pieces we'll have to build sooner or later, e.g. `bin/trigger cancel` or whatever.
- Intentionally not realtime: This design puts execution guarantees far above realtime concerns, and will not give you precise event execution at 1-second resolution. I think this is the correct goal to pursue architecturally, and certainly correct for subscriptions and meeting reminders. Events which execute after they have become irrelevant can simply decline to do anything (like a meeting reminder which executes after the meeting is over).
In general, the expectation for applications is:
- When creating an object (like a calendar event) that needs to trigger a scheduled action, write a trigger (and save the PHID if you plan to update it later).
- The daemon will process the event and schedule the action efficiently, in a race-free way.
- If you want to move the action, update the trigger and the daemon will take care of it.
- Your action will eventually dump a task into the task queue, and the task daemons will actually perform it.
Test Plan:
Using a test script like this:
```
<?php
require_once 'scripts/__init_script__.php';
$trigger = id(new PhabricatorWorkerTrigger())
->setAction(
new PhabricatorLogTriggerAction(
array(
'message' => 'test',
)))
->setClock(
new PhabricatorMetronomicTriggerClock(
array(
'period' => 33,
)))
->save();
var_dump($trigger);
```
...I queued triggers and ran the daemon:
- Verified triggers fire;
- verified triggers reschedule;
- verified trigger events show up in the web UI;
- tried different periods;
- added some triggers while the daemon was running;
- examined `phd debug` output for anything suspicious.
It seems to work in trivial use case, at least.

- Trigger an event at a specific time (e.g., a meeting reminder notification).
- Trigger an event on the Nth day of every month (e.g., a subscription bill).
At some point, we'll presumably add a rule for T2896 (maybe using the "RRULE" spec) so you can do stuff like "the second to last thursday of every month", etc., but we don't need that for now.
(The "Nth day of every month, or move it back if no such day exists" rule doesn't seem to be expressible with the "RRULE" format, so implementing that wouldn't give us a superset of this. I think this rule is correct and desirable for this purpose, though.)
