Fix performance issue with large changesets in Differential

Summary:
Fixes T3151. Javelin treats a behavior without parameters as a global behavior and invokes it only once no matter how many times it is initialized (this is necessarily correct for any reasonable behavior, as the inputs do not vary). A recent patch changed `differential-dropdown-menus` from a zero-argument global behavior to an implicitly nonzero-argument behavior by adding `pht`.

Currently, we initialize the behavior next to dropdown menu creation, so this resulted in `O(N^2)` initializations of the menus. For large diffs, this locks browsers. Instead, initialize outside of the dropdown loop so we ginitialize each menu just once.

Test Plan: Viewed a 2,000 file diff without browser lock.

Fix tab-focus of Tokenizers

Summary: Fixes T3140. Previously, we added the highlight class only on explicit events, but not on actual focus events (e.g., via tab).

Test Plan: Tabbed into a tokenizer. Clicked a tokenizer. Tabbed out of a tokenizer. Clicked out of a tokenizer. Shift-tabbed out of a tokenizer. Verified highlight state was always correct.

Diffusion - move DiffusionBrowseQuery => Conduit

Summary: see title. Ref T2784.

Test Plan:
In diffusion, for each of SVN, Mercurial, and Git, I loaded up /diffusion/CALLSIGN/. I verified the README was displayed and things looked good. Next I clicked on "browse" on the top-most commit and verified things looked correct. Also clicked through to a file for a good measure and things looked good.
In owners, for each of SVN, Mercurial, and Git, I played around with the path typeahead / validator. It worked correctly!

Add action icons to object list views

Summary:
We have a few interfaces where add "Edit", "Delete" or some other action to a list. Currently, this happens via icons, but these are cumbersome and weird, are inconsistent, can't be workflow'd, are hard to hit on desktops and virtually impossible to hit on mobile, and generally just feel iffy to me. Prominent examples are Projects and Flags. I'd like to try adding an "edit" action to Maniphest (to provide quick edit from list views, basically). It looks like some of Releeph would benefit here, as well.

Instead, provide first-class actions:

{F42978}

They produce targets which my meaty ham-fists can plausibly hit on mobile, too:

{F42979}

(We could do some kind of swipe-to-expose thing eventually, but I think putting them by default is OK?)

Test Plan: Added UIExamples. Checked desktop/mobile.

Summary: title. Ref T2784.

Test Plan: foreach of SVN, Mercurial, and Git, loaded up a repository. Verified that only git had a tags box and it showed up correctly. Went to CALLSIGN/tags and verified that only git had a tags box and it showed up correctly. Went to various commits across vcs and verified it said "none" unless it was a git commit that also was tagged.

ReleephRequest xactions

Summary:
Migrate to `PhabricatorApplicationTransactions` (`ReleephRequestTransactions` applied by `ReleephRequestTransactionalEditor`, instead of `ReleephRequestEvents` created by `ReleephRequestEditor`) and migrate all the old events into transactions.  Email is supported in the standard way (no more `ReleephRequestMail`) as well.

This also collapses the Releeph request create and edit controllers into one class, as well as breaking everyone's subject-based mail rules by standardising them (but which should be more easily filtered by looking at headers.)

Test Plan:
* Make requests, then pick them.
* Pick and revert the same request so that discovery happens way after `arc` has told Releeph about what's been happening.
* Try to pick something that fails to pick in a project with pick instructions (and see the instructions are in the email.)
* Load all of FB's Releeph data into my DB and run the `storage upgrade` script.
* Request a commit via the "action" in a Differential revision.

Make repository pulls testable

Summary:
Ref T2784. This moves us toward being able to test the background and Conduit pipelines for repositories. In particular:

  - Separate the logic for pulling repositories (`git pull`, `hg pull`) out of `PhabricatorRepositoryPullLocalDaemon` and put it in `PhabricatorRepositoryPullEngine`. This allows repositories to be pulled directly without invoking the daemons.
  - Add tests for the engine, including a future-looking base test case.
  - Add basic `PhutilDirectoryFixture`-based repositories.

Next steps:

  # Do the same for repo discovery.
  # Then we can start writing tests against specific Conduit methods.

Test Plan: Ran unit tests. Ran `bin/repository pull` on SVN, Hg and Git repositories. Ran `bin/phd debug pulllocal`.
