Ref T12298. The PullLocal daemon has had hibernation code for a little while, but it never actually activated because we don't sleep for more than 15 seconds in any case.
Add a maximum sleep instead and use that to control the longest sleep we'll do for hibernation purposes.
Also, when a repository or repository URI is edited, write a NEEDS_UPDATE event into the message table to make sure the daemons de-hibernate.
Test Plan: Used `bin/phd debug pull`, saw the daemon actually hibernate instead of just sleeping for 15 seconds.

Summary:
Ref T11665. Fixes T7865. When we restart the daemons, the repository pull daemon currently resets the cooldowns on all of its pulls. This can generate a burst of initial load when restarting a lot of instance daemons (as in the Phacility cluster), described in T7865. This smooths things out so that recent pulls are considered, and any repositories which were waiting keep waiting.
Somewhat counterintuitively, hosted repositories write `TYPE_FETCH` status messages, so this should work equally well for hosted and observed repositories.
This also paves the way for better backoff behavior on repository errors, described in T11665. The error backoff now uses the same logic that the standard backoff does. The next change will make backoff computation consider recent errors.
(This is technically too large for repositories which have encountered one error and have a low commit rate, but I'll fix that in the following change; this is just a checkpoint on the way there.)
Test Plan: Ran `bin/phd debug pull`, saw the daemon compute reasonable windows based on previous pull activity.

Summary:
Fixes T10940. Two issues currently:
First, `PullLocal` deamon refuses to update non-cluster repositories on cluster devices. However, this is surprising/confusing/bad because as soon as you enroll a repository host in the cluster, most of the repositories on it stop working until you `clusterize` them. This is especially confusing because the documentation gives you a very nice, gradual walkthrough about going through things slowly and being able to check your work at every step, but we really drop you off a bit of a cliff here. The workflow implied by the documentation is a desirable one.
This operation is generally only unsafe/problematic if the daemon would be creating a //new// working copy. If a working copy already exists, we can reasonably guess that it's almost certainly because you've enrolled a previously un-clustered host into a new cluster. This allows the nice, gradual workflow the documentation describes to proceed as expected, without any weird surprises.
Instead of refusing to update these repositories, only refuse to update them if updating would create a new working copy. This should make transitioning much smoother without any meaningful reduction in safety.
Second, the lower-level `bin/repository update`, `refs`, `mirror`, etc., commands don't apply this same check. However, these commands are potentially just as dangerous. Use the same code to do a similar check there, making sure we only operate on repositories that are either expected to be on the current device, or which already exist here.
Test Plan:
- Ran `bin/phd debug pull`, saw diagnostic information choose to update most repositories (including some non-cluster repositories) but properly skip non-cluster repositories that do not exist locally.
- Ran `bin/repository update`, etc., saw the command apply consistent rules to the rules applied by `PullLocal` and refuse to update non-local repositories it would need to create.

In particular:
- As an optimization, we process closeable branches ("master") first, then process uncloseable branches ("epriestley-devel"). This means that in the common case we can insert a commit as closeable immediately when it is discovered, the first pass through the pipeline will get it right, and the "ref update" step will never need to do any meaningful work.
- Commits which do not initially appear on a closeable branch, but later move to one (via merges or ref moves) will now be caught in the ref update step, have the closeable flag set, and have a message step re-queued.

Summary:
Ref T4327. I want to make change parsing testable; one thing which is blocking this is that the Git discovery process is still part of `PullLocal` daemon instead of being part of `DiscoveryEngine`. The unit test stuff which I want to use for change parsing relies on `DiscoveryEngine` to discover repositories during unit tests.
The major reason git discovery isn't part of `DiscoveryEngine` is that it relies on the messy "autoclose" logic, which we never implemented for Mercurial. Generally, I don't like how autoclose was implemented: it's complicated and gross and too hard to figure out and extend.
Instead, I want to do something more similar to what we do for pushes, which is cleaner overall. Basically this means remembering the old branch heads from the last time we parsed a repository, and figuring out what's new by comparing the old and new branch heads. This should give us several advantages:
- It should be simpler to understand than the autoclose stuff, which is pretty mind-numbing, at least for me.
- It will let us satisfy branch and tag queries cheaply (from the database) instead of having to go to the repository. We could also satisfy some ref-resolve queries from the database.
- It should be easier to extend to Mercurial.
This implements the basics -- pretty much a table to store the cursors, which we update only for Git for now.
Test Plan:
- Ran migration.
- Ran `bin/repository discover X --trace --verbose` on various repositories with branches and tags, before and after modifying pushes.

Maniphest Tasks: T2350, T2231
Differential Revision: https://secure.phabricator.com/D7467
Summary: Ref T2230. This cleans up D7442, by using `git for-each-ref` everywhere we can, in a basically reasonable way.
Test Plan:
In bare and non-bare repositories:
- Ran discovery with `bin/repository discover`;
- listed branches on `/diffusion/X/`;
- listed tags on `/diffusion/X/`;
- listed tags, branches and refs on `/diffusion/rXnnnn`.

Summary:
Ref T2230. Although all the non-bare commands //run// fine in bare repos, not all of them do exactly the same thing.
This could use further cleanup, but at least get it working again for now.
Test Plan: Ran `bin/repository pull`, `bin/repository discover`, viewed Diffusion (looked at branch table), viewed a commit (looked at "Branches"), for bare and non-bare git repos.

Summary:
Fixes T3217. Ref T776. Ref T1493. Broadly, this introduces a mechanism which works like this:
- When a repository is created, we set an "importing" flag.
- After discovery completes, we check if a repository has no importing commits. Basically, this is the first time we catch up to HEAD.
- If we're caught up, clear the "importing" flag.
This flag lets us fix some issues:
- T3217. Currently, when you import a new repository and users have rules like "Email me on every commit ever" or "trigger an audit on every commit", we take a bunch of publish actions. Instead, implicitly disable publishing during import.
- An imported but un-pulled repository currently has an incomprehensible error on `/diffusion/X/`. Fix that.
- Show more cues in the UI about importing.
- Made some exceptions more specific.
Test Plan:
This is the new screen for a completely new repo, replacing a giant exception:
{F75443}
- Created a repository, saw it "importing".
- Pulled and discovered it.
- Processed its commits.
- Ran discovery again, saw import flag clear.
- Also this repository was empty, which hit some of the other code.
This is the new "parsed empty repository" UI, which isn't good, but is less broken:

Summary:
- Don't try to pull hosted repos.
- Also, fix the `--verbose` + `--trace` interaction for `bin/repository`.
- Also, fix a couple of unit tests which got tweaked earlier.
Test Plan:
$ ./bin/repository pull GTEST --verbose
Pulling 'GTEST'...
Repository "GTEST" is hosted, so Phabricator does not pull updates for it.
Done.
