Don't try to set anonymous session cookie on CDN/file domain

Summary:
Ref T2380. If an install has a CDN domain configured, but does not list it as an alternate domain (which is standard/correct, but not incredibly common, see T2380), we'll currently try to set anonymous cookies on it. These will correctly fail security rules.

Instead, don't try to set these cookies.

I missed this in testing yesterday because I have a file domain, but I also have it configured as an alternate domain, which allows cookies to be set. Generally, domain management is due for some refactoring.

Test Plan: Set file domain but not as an alternate, logged out, nuked file domain cookies, reloaded page. No error after patch.

Don't let Diffusion show that an importing repository is "100%" imported

Summary:
A few users have hit this and found it confusing. Currently, it means "more than 99.95%", which is very different from "100%". Instead:

  - show an extra digit of precision; and
  - cap the display at "99.99%", so it's more clear that work is still happening.

Test Plan: Faked it and saw it cap at 99.99%.

Allow repository mirrors even if the repository is hosted elsewhere.

Summary:
I'm not sure if this is desired functionality, but we happen to need
mirroring of our repository which is not hosted by phabricator, and as far as
I can tell the mirroring code does not depend on the hosting code.

Test Plan:
Setup mirror with SSH credentials to github, pushed changes to
elsewhere hosted repository, commits got mirrored to github.

Separate repository mirroring into an Engine and provide `bin/repository mirror`

Summary:
Ref T4338. Currently, there's no diagnostic command to execute mirroring (so I can't give users an easy command to run), and it's roughly the last piece of real logic left in the PullLocal daemon.

Separate mirroring out, and provide `bin/repository mirror`.

Test Plan:
  - Ran `bin/repository mirror` to mirror a repository.
  - Ran PullLocalDaemon and verified it also continued mirroring normally.

If repository mirroring fails, keep trying the other mirrors

Summary: Ref T4338. Currently, if you have several mirrors and the first one fails, we won't try the other mirrors (since we'll throw and that will take us out of the mirroring process). Instead, try each mirror even if one fails, and then throw an AggregateException with all the failures.

Test Plan:
  - Ran `bin/repository mirror` normally.
  - Faked an exception, ran again, got the AggregateException I expected.

Make "Home" a formal application

Summary: Ref T3979. Currently, the home page lives in an old application called "directory" and is informally defined. Make it a real application called "Home", with a formal definition. It isn't launchable and can't be uninstalled.

Test Plan: Loaded home, saw exact same stuff.

Allow logged-out users to view the homepage

Summary: Fixes T3979. The content isn't necessarily very good yet (see T4103, T3583), but this makes it work (e.g., not be a login screen).

Test Plan: Loaded home as a logged-out user on a public install, saw home instead of login.

Update DifferentialDiff: add repositoryPHID, drop parentRevisionID

Summary:
Moves away from ArcanistProjects:

  - Adds storage for diffs to be directly associated with a repository (instead of indirectly, through arcanist projects). Not really populated yet.
  - Drops `parentRevisionID`, which is obsoleted by the "Depends On" edge. This is not exposed in the UI anywhere and doesn't do anything. Resolves TODO.

Test Plan: Ran storage upgrades, browsed around, lots of `grep`.
