Don't show empty attributes.

Summary: Some places we pass in empty strings and get hanging middots. Would prefer not have the middot, and let the developer decide if they should set a 'nothing here' state.

Test Plan: Checked Repositories with no lint messages.

Begin improving the soundness of received mail

Summary:
We/I broke a couple of things here recently (see D5911) and are doing some work here in general (see D5912, etc.).

Generally, this code is pretty oldschool and not especially well architected for modern application-oriented Phabricator. It hardcodes a lot of stuff which should be applications' responsibilites.

Take the first steps toward making it more solid to reduce the risk here. In particular:

  - Factor out the "self mail" and "duplicate mail" checks and add unit tests.
  - Make Message-ID hash handling automatic.

Test Plan: Ran unit tests.

Move some received mail responsibility to applications

Summary:
Ref T1205. Continuation of D5915.

Currently, `PhabricatorMetaMTAReceivedMail` has //all// the logic for routing mail. In particular:

  - New mail receivers in applications must edit it.
  - Mail receivers don't drop out when applications are uninstalled.

Applications have some logic in subclasses of `PhabricatorMailReplyHandler`, but this class is a bit of a mess. It is also heavily based on the assumption that mail receivers are objects (like revisions), but this is not true in at least two cases today (creating new tasks with `bugs@`, creating a new Conpherence thread) and likely other cases in the future (e.g., revision-by-mail).

Move this logic into a new `PhabricatorMailReceiver` classtree. This is similar to `PhabricatorMailReplyHandler` but a bit cleaner and more general. I plan to heavily reduce the responsibilities of `PhabricatorMailReplyHandler` or possibly eliminate it entirely.

For now, the new classtree doesn't do much of interest. The only behavioral change this diff causes is that Phabricator will now reject mail to an application when that application is uninstalled.

I also moved all the `ReplyHandler` classes into `mail/` directories in their respective applications.

Test Plan: Unit tests, used receive test to route mail to various objects.

Summary: title does not say it all; also added conduit wrappers for rawdiffquery and lastmodifiedquery. These get the wrapper treatment since they are used in daemons. Ref T2784.

Test Plan: for each of the 3 VCS, did the following: 1) loaded up CALLSIGN and verified 'Modified' column data showed up correctly in Browse Repository box. 2) loaded up the "change" view for a specific file and verified content showed up correctly. 3) loaded up a specific commit and noted the changes ajax loaded A-OK
