This is primarily a client request, and a little bit use-case specific, but policies seem to be holding up well and I'm getting more comfortable about maintaining this. Much if it can run through ApplicationTransactions.
Allow the ability to edit status, policies, priorities, assignees and projects of a task to be restricted to some subset of users. Also allow bulk edit to be locked. This affects the editor itself and the edit, view and list interfaces.

Ref T2217. This partially retreads the ground from D7115.
- We're rendering silly transactions about descriptions when creating tasks. Hide those.
- Move the "created" transaction back to status. This fixes two things that are otherwise more of a mess than I'd anticipated:
- It fixes Reports without making a mess (see <https://github.com/facebook/phabricator/issues/395>).
- It renders old transactions properly (i.e., "created" instead of "reopened" for tasks older than the migration).
- Be explicit about action strength, so emails always say the most important thing in the subject.
Test Plan: Created and edited tasks, looked at resulting transactions, saw a cleaner transaction record.

Ref T603. Make almost every task read policy-aware. Notable exceptions are:
- Edge editor -- this stuff is prescreened and should be moved to ApplicationTransactions eventually anyway.
- Search/attach stuff -- this stuff needs some general work. The actual list should be fine since you can't pull handles. There may be a very indirect hole here where you could attach an object you can't see (but do know the ID of) to an object you can see. Pretty fluff.
- The "Tasks" field in Differential will let you reference objects you can't see. Possibly this is desirable, in the case of commandeering revisions. Mostly, it was inconvenient to get a viewer (I think).

Summary:
Ref T2217. This is the risky, hard part; everything after this should be smooth sailing. This is //mostly// clean, except:
- The old format would opportunistically combine a comment with some other transaction type if it could. We no longer do that, so:
- When migrating, "edit" + "comment" transactions need to be split in two.
- When editing now, we should no longer combine these transaction types.
- These changes are pretty straightforward and low-impact.
- This migration promotes "auxiliary field" data to the new CustomField/StandardField format, so that's not a straight migration either. The formats are very similar, though.
Broadly, this takes the same attack that the auth migration did: proxy all the code through to the new storage. `ManiphestTransaction` is now just an API on top of `ManiphestTransactionPro`, which is the new storage format. The two formats are very similar, so this was mostly a straight copy from one table to the other.
Test Plan:
- Without performing the migration, made a bunch of edits and comments on tasks and verified the new code works correctly.
- Droped the test data and performed the migration.
- Looked at the resulting data for obvious discrepancies.
- Looked at a bunch of tasks and their transaction history.
- Used Conduit to pull transaction data.
- Edited task description and clicked "View Details" on transaction.

- If nothing breaks, it's a straight shot to nuking ManiphestTransaction callsite by callsite.

Summary:
The search indexing API has several problems right now:
- Always runs in-process.
- It would be nice to push this into the task queue for performance. However, the API currently passses an object all the way through (and some indexers depend on preloaded object attributes), so it can't be dumped into the task queue at any stage since we can't serialize it.
- Being able to use the task queue will also make rebuilding indexes faster.
- Instead, make the API phid-oriented.
- No uniform indexing API.
- Each "Editor" currently calls SomeCustomIndexer::indexThing(). This won't work with AbstractTransactions. The API is also just weird.
- Instead, provide a uniform API.
- No uniform CLI.
- We have `scripts/search/reindex_everything.php`, but it doesn't actually index everything. Each new document type needs to be separately added to it, leading to stuff like D3839. Third-party applications can't provide indexers.
- Instead, let indexers expose documents for indexing.
- Not application-oriented.
- All the indexers live in search/ right now, which isn't the right organization in an application-orietned view of the world.
- Instead, move indexers to applications and load them with SymbolLoader.
Test Plan:
- `bin/search index`
- Indexed one revision, one task.
- Indexed `--type TASK`, `--type DREV`, etc., for all types.
- Indexed `--all`.
- Added the word "saboteur" to a revision, task, wiki page, and question and then searched for it.
- Creating users is a pain; searched for a user after indexing.
- Creating commits is a pain; searched for a commit after indexing.
- Mocks aren't currently loadable in the result view, so their indexing is moot.

We need both of these applications to work with the same setting because we don't use multiplexing to prevent sending multiple e-mails to people in lists.
I also believe that the default behavior should just work in most setups.
I've tried several different combinations of putting "Re:" and none of them seems to always work in both clients.

Summary:
- Add an explicit multiplexing option, and enable it by default. This is necessary for Mail.app to coexist with other clients ("Re:" breaks outlook at the very least, and generally sucks in the common case), and allows users with flexible clients to enable subject variance.
- Add an option for subject line variance. Default to not varying the subject, so mail no longer says [Committed], [Closed], etc. This is so the defaults thread correctly in Gmail (not entirely sure this actually works).
- Add a preference to enable subject line variance.
- Unless all mail is multiplexed, don't enable or respect the "Re" or "vary subject" preferences. These are currently shown and respected in non-multiplex cases, which creates inconsistent results.
NOTE: @jungejason @nh @vrana This changes the default behavior (from non-multiplexing to multiplexing), and might break Facebook's integration. You should be able to keep the same behavior by setting the options appropriately, although if you can get the new defaults working they're probably better.
Test Plan:
Send mail from Maniphest, Differential and Audit. Updated preferences. Enabled/disabled multiplexing. Things seem OK?
NOTE: I haven't actually been able to repro the Gmail threading issue so I'm not totally sure what's going on there, maybe it started respecting "Re:" (or always has), but @cpiro and @20after4 both reported it independently. This fixes a bunch of bugs in any case and gives us more conservative set of defaults.
I'll see if I can buff out the Gmail story a bit but every client is basically a giant black box of mystery. :/

Like the title says, similar to Facebook Tasks.
Not sure how I really feel about this, but I guess it's kind of OK? I never used
this feature in Facebook Tasks but I think some people like it.
The drag-and-drop to repri across priorities feels okayish.
Because subpriority is a double and we just split the difference when
reprioritizing, you lose ~a bit of precision every time you repri two tasks
against each other and so you can break it by swapping the priorities of two
tasks ~50 times. This case is pretty silly and pathological. We can add some
code to deal with this at some point if necessary.
I think this also fixes the whacky task layout widths once and for all.
(There are a couple of minor UI glitches like headers not vanishing and header
counts not updating that I'm not fixing because I am lazy.)

Summary:
A few similar requests have come in across several tools and use cases that I
think this does a reasonable job of resolving.
We currently send one email for each update an object receives, but these aren't
always appreciated:
- Asana does post-commit review via Differential, so the "committed" mails are
useless.
- Quora wants to make project category edits to bugs without spamming people
attached to them.
- Some users in general are very sensitive to email volumes, and this gives us
a good way to reduce the volumes without incurring the complexity of
delayed-send-batching.
The technical mechanism is basically:
- Mail may optionally have "mail tags", which indicate content in the mail
(e.g., "maniphest-priority, maniphest-cc, maniphest-comment" for a mail which
contains a priority change, a CC change, and a comment).
- If a mail has tags, remove any recipients who have opted out of all the
tags.
- Some tags can't be opted out of via the UI, so this ensures that important
email is still delivered (e.g., cc + assign + comment is always delivered
because you can't opt out of "assign" or "comment").
Test Plan:
- Disabled all mail tags in the web UI.
- Used test console to send myself mail with an opt-outable tag, it was
immediately dropped.
- Used test console to send myself mail with an opt-outable tag and a custom
tag, it was delivered.
- Made Differential updates affecting CCs with and without comments, got
appropriate delivery.
- Made Maniphest updates affecting project, priority and CCs with and without
comments, got appropriate delivery.
