Ref T4809. Currently, buildables have a status field but nothing populates it. Populate it:
- When builds change state, update the Buildable state.
- Use the new Buildable state on the web UI.
- Return the new Buildable state from Conduit.

- Provide `bin/harbormaster update Bxxx ...` to force foreground update of a Buildable.

Summary:
For Harbormaster tasks which want to poll or wait, this lets them say "try again a little later" without having to sleep and hold a queue slot.
This is basically the same as failing, except that we don't increment the failure counter. Instead, we just set the current lease to the correct length and then exit. The task will be retried after the lease expires.
Test Plan: Using both `bin/harbormaster` and `phd debug taskmaster`, ran a lot of waiting tasks through the queue, faking them to either yield or not yield in a controlled manner. The queue responded as expected, yielding tasks appropraitely and retrying them later.

- scheduling repository updates; and
- actually updating repositories.
Move the "actually updating" part into a new `bin/repository update` command, which basically runs the pull, discover, refs and mirror commands. This will let the parent process focus on scheduling in a more understandable way and update multiple repositories at once. It also makes it easier to debug and understand update behavior since the non-scheduling pipeline can be run separately.

This query is unusual (it requires changesets, and does not accept IDs). This keeps us from having to load changeset -> diff -> revision in order to do policy checks. We could also fix this with smarter policy checks and caching, but I'd rather not open that can of worms for now. This object is very low level and relatively unusual, and this small deviation from convention seems like the cleanest cut to make to keep this from snowballing.

Summary:
Ref T4371. Ref T4699. Fixes T3994.
Currently, we're very conservative about sending errors back to users. A concern I had about this was that mistakes could lead to email loops, massive amounts of email spam, etc. Because of this, I was pretty hesitant about replying to email with more email when I wrote this stuff.
However, this was a long time ago. We now have Message-ID deduplication, "X-Phabricator-Sent-This-Mail", generally better mail infrastructure, and rate limiting. Together, these mechanisms should reasonably prevent anything crazy (primarily, infinite email loops) from happening.
Thus:
- When we hit any processing error after receiving a mail, try to send the author a reply with details about what went wrong. These are limited to 6 per hour per address.
- Rewrite most of the errors to be more detailed and informative.
- Rewrite most of the errors in a user-facing voice ("You sent this mail..." instead of "This mail was sent..").
- Remove the redundant, less sophisticated code which does something similar in Differential.
Test Plan:
- Using `scripts/mail/mail_receiver.php`, artificially received a pile of mail.
- Hit a bunch of different errors.
- Saw reasonable error mail get sent to me.
- Saw other reasonable error mail get rate limited.

Summary:
This adds a system which basically keeps a record of recent actions, who took them, and how many "points" they were worth, like:
epriestley email.add 1 1233989813
epriestley email.add 1 1234298239
epriestley email.add 1 1238293981
We can use this to rate-limit actions by examining how many actions the user has taken in the past hour (i.e., their total score) and comparing that to an allowed limit.
One major thing I want to use this for is to limit the amount of error email we'll send to an email address. A big concern I have with sending more error email is that we'll end up in loops. We have some protections against this in headers already, but hard-limiting the system so it won't send more than a few errors to a particular address per hour should provide a reasonable secondary layer of protection.
This use case (where the "actor" needs to be an email address) is why the table uses strings + hashes instead of PHIDs. For external users, it might be appropriate to rate limit by cookies or IPs, too.
To prove it works, I rate limited adding email addresses. This is a very, very low-risk security thing where a user with an account can enumerate addresses (by checking if they get an error) and sort of spam/annoy people (by adding their address over and over again). Limiting them to 6 actions / hour should satisfy all real users while preventing these behaviors.

Summary:
Ref T1049. Allows external systems to send a message to a build target. The primary intended use case is:
- You make an HTTP request to Jenkins.
- The build goes into a "waiting" state.
- Later, Jenkins calls `harbormaster.sendmessage` to report that the target passed or failed.
- The build continues as appropriate.
This is deceptively complicated because:
- There are a lot of race concerns. We might get a message back from an external system before it even responds to the request we made. We want to make sure we process these messages no matter when we receive them.
- These messages need to be sent to a build target (vs a build or buildable) because we'll get into trouble with parallelization later on otherwise (Jenkins is told to do 3 builds; we can't tell which ones failed or what overall state is unless the message are sent to targets).
- I initially thought about implementing this as a separate "Wait for a response from an external system" build step. This gets a lot more complicated for users once we do parallelization, though. Particularly, in the case where you've told Jenkins to do 3 builds, the three "wait" steps need to know which target they're waiting for (and jenkins needs to know some unique identifier for each target). So this pretty much boils down to a more complicated, more error-prone version of using target PHIDs.
This makes the already-muddy Build UI a bit worse, but it needs a general clarity pass anyway (it's showing way too much uninteresting data, and should show a better summary of results instead).
Test Plan:
- This doesn't really do anything interesting yet.
- Used Conduit to send messages to build plans.
