Summary:
Ref T11823. Currently, we have a "RefCursor" table which stores rows like `<branch or tag name, commit it is pointing at>` with some more data.
Because Mercurial can have a single branch pointing at several different places, this table must allow multiple rows with the same branch or tag name.
Among other things, this means there isn't a single PHID which can be used to identify a branch name in a stable way. However, we have several UIs where we want to be able to do this.
Some specific examples where we run into trouble: in Mercurial, if there are 5 heads for "default", that means there are 5 phids. And currently, if someone deletes a branch, we lose the PHID for it. Instead, we'd rather retain it so the whole world doesn't break if you accidentally delete a branch and then fix it a little later.
(I'll likely hold this until the rest of the logic is fleshed out a little more in followup changes.)
Test Plan: Ran `bin/storage upgrade`, saw the table get created without warnings.

Ref T12819. This addresses two issues:
- One practical issue is that right now, if you search for "dog cat", and they appear in different fields (for example, "dog" appears ONLY in the title, while "cat" appears ONLY in a comment) we won't find the document. This is somewhat rare -- usually, if "dog" appears in the title, it's also repeated in the description -- but I think clearly a bug. To attack this, start automatically creating a virtual "ALL" field with the full document text which we'll use as the primary thing we match against.
- For fields which may occur more than once -- today, only comments -- aggregate them all into one big "all of the text" row instead of writing one row per comment. This partly addresses the first point ("dog" in one comment and "cat" in a different comment won't be found) and partly makes some of the query gymnastics easier.

Ran `bin/storage upgrade`, ran `bin/search index <Txxx>`, saw sensible corpus values in the database:

Ref T12819. I gave this stuff a sweet code name because all the terms related to "fulltext" and "search" already mean 5 different things. It, uh, ferrets out documents for you?
I'm building this to work a lot like the existing ngram index, which seems to work pretty well. If this sticks, it will auto-resolve the join issue (in T12443) by letting us do the entire thing locally in a JOIN and thus dodge a lot of mess.
This index gets built alongside other indexes, but only shows up in the UI if you have prototypes enabled. If you do, it appears under the existing fulltext field in Maniphest. No existing functionality is affected or disrupted.
NOTE: The query engine half of this is still EXTREMELY primitive, and this probably performs worse than the existing field for now. If this doesn't show obvious signs of being awful on `secure` I'll improve that in followup changes.

In T12956, I plan to make changes so that personal queries are always first, then global/builtin queries. Without changing the "default query" rule, this will make it harder to have, for example, some custom queries in Differential but still run a global query like "Active" by default. To make this work, you'd have to save a personal copy of the "Active" query, then put it at the top.
This feels a bit cumbersome and this rule is kind of implicit and a little weird anyway. To make this work a little better as we make changes here, add an explicit pinning action, like the one we have in Project ProfileMenus.
You can now explicitly choose a query to make default.
Test Plan:
- Browsed without pinning anything, saw normal behavior.

Ref T12509. This adds support for HMAC+SHA256 (instead of HMAC+SHA1). Although HMAC+SHA1 is not currently broken in any sense, SHA1 has a well-known collision and it's good to look at moving away from HMAC+SHA1.
The new mechanism also automatically generates and stores HMAC keys.
Currently, HMAC keys largely use a per-install constant defined in `security.hmac-key`. In theory this can be changed, but in practice essentially no install changes it.
We generally (in fact, always, I think?) don't use HMAC digests in a way where it matters that this key is well-known, but it's slightly better if this key is unique per class of use cases. Principally, if use cases have unique HMAC keys they are generally less vulnerable to precomputation attacks where an attacker might generate a large number of HMAC hashes of well-known values and use them in a nefarious way. The actual threat here is probably close to nonexistent, but we can harden against it without much extra effort.
Beyond that, this isn't something users should really have to think about or bother configuring.
Test Plan:
- Added unit tests.
- Used `bin/files integrity` to verify, strip, and recompute hashes.
- Tampered with a generated HMAC key, verified it invalidated hashes.

Summary:
The goal is to make fulltext search back-ends more extensible, configurable and robust.
When this is finished it will be possible to have multiple search storage back-ends and
potentially multiple instances of each.
Individual instances can be configured with roles such as 'read', 'write' which control
which hosts will receive writes to the index and which hosts will respond to queries.
These two roles make it possible to have any combination of:
* read-only
* write-only
* read-write
* disabled
This 'roles' mechanism is extensible to add new roles should that be needed in the future.
In addition to supporting multiple elasticsearch and mysql search instances, this refactors
the connection health monitoring infrastructure from PhabricatorDatabaseHealthRecord and
utilizes the same system for monitoring the health of elasticsearch nodes. This will
allow Wikimedia's phabricator to be redundant across data centers (mysql already is,
elasticsearch should be as well).
The real-world use-case I have in mind here is writing to two indexes (two elasticsearch clusters
in different data centers) but reading from only one. Then toggling the 'read' property when
we want to migrate to the other data center (and when we migrate from elasticsearch 2.x to 5.x)
Hopefully this is useful in the upstream as well.
Remaining TODO:
* test cases
* documentation
