Summary:
Depends on D19322. Ref T13120. Ref T12414.
Currently, `AlmanacDevice` has a bit of a beast of a `TYPE_INTERFACE` transaction that fully creates a complex Interface object. This isn't very flexible or consistent, and Interfaces are complex enough to reasonably have their own object behaviors (for example, they have their own PHIDs).
The complexity of this transaction makes modularizing `AlmanacDevice` transactions tricky. To simplify this, move Interface toward having its own set of normal transactions.
This change just adds some reasonable-looking transactions; it doesn't actually hook them up in the UI or make them reachable. I'll test that they actually work as I swap the UI over.
We may also have some code using the `TYPE_INTERFACE` transaction in Phacility support stuff, so that may need to wait a week to actually phase out.
Test Plan: Ran `bin/storage upgrade` and `arc liberate`. This code isn't reachable yet.

Summary:
Ref T13083. Facts has a fair amount of weird hardcoding and duplication of responsibilities. Reduce this somewhat: no more hard-coded fact aggregates, no more database-driven list of available facts, etc. Generally, derive all objective truth from FactEngines. This is more similar to how most other modern applications work.
For clarity, hopefully: rename "FactSpec" to "Fact". Rename "RawFact" to "Datapoint".
Split the fairly optimistic "RawFact" table into an "IntDatapoint" table with less stuff in it, then dimension tables for the object PHIDs and key names. This is primarily aimed at reducing the row size of each datapoint. At the time I originally wrote this code we hadn't experimented much with storing similar data in multiple tables, but this is now more common and has worked well elsewhere (CustomFields, Edges, Ferret) so I don't anticipate this causing issues. If we need more complex or multidimension/multivalue tables later we can accommodate them. The queries a single table supports (like "all facts of all kinds in some time window") don't make any sense as far as I can tell and could likely be UNION ALL'd anyway.
Remove all the aggregation stuff for now, it's not really clear to me what this should look like.

Ref T13043. In D18898 I moved VCS passwords to the new shared infrastructure.
Before account passwords can move, we need to make two changes:
- For legacy reasons, VCS passwords and Account passwords have different "digest" algorithms. Both are more complicated than they should be, but we can't easily fix it without breaking existing passwords. Add a `PasswordHashInterface` so that objects which can have passwords hashes can implement custom digest logic for each password type.
- Account passwords have a dedicated external salt (`PhabricatorUser->passwordSalt`). This is a generally reasonable thing to support (since not all hashers are self-salting) and we need to keep it around so existing passwords still work. Add salt support to `AuthPassword` and make it generate/regenerate when passwords are updated.
Then add a nice story about password digestion.

Summary:
Ref T13043. Currently:
- Passwords are stored separately in the "VCS Passwords" and "User" tables and don't share as much code as they could.
- Because User objects are all over the place in the code, password hashes are all over the place too (i.e., often somewhere in process memory). This is a very low-severity, theoretical sort of issue, but it could make leaving a stray `var_dump()` in the code somewhere a lot more dangerous than it otherwise is. Even if we never do this, third-party developers might. So it "feels nice" to imagine separating this data into a different table that we rarely load.
- Passwords can not be //revoked//. They can be //deleted//, but users can set the same password again. If you believe or suspect that a password may have been compromised, you might reasonably prefer to revoke it and force the user to select a //different// password.
This change prepares to remedy these issues by adding a new, more modern dedicated password storage table which supports storing multiple password types (account vs VCS), gives passwords real PHIDs and transactions, supports DestructionEngine, supports revocation, and supports `bin/auth revoke`.
It doesn't actually make anything use this new table yet. Future changes will migrate VCS passwords and account passwords to this table.
(This also gives third party applications a reasonable place to store password hashes in a consistent way if they have some need for it.)

Summary:
Ref T12539. See PHI190. Currently, each Diff has a `revisionID`, but Revisions do not point at the current active diff. To find the active diff for a given revision, we need to issue a separate query.
Furthermore, this query is inefficient for bulk loads: if we have a lot of revisions, we end up querying for all diff IDs for all those revisions first, then selecting the largest ones and querying again to get the actual diff objects. This strategy could likely be optimized but the query is a mess in any case.
In several cases, it's useful to have the active diff PHID without needing to do a second query -- sometimes for convenience, and sometimes for performance.
T12539 is an example of such a case: it would be nice to refine the bucketing logic (which only depends on active diff PHIDs), but it feels bad to make the page heavier to do it.
For now, this is unused. I'll start using it to fix the bucketing issue, and then we can expand it gradually to address other performance/convenience issues.

If an ngram is listed in the "common" table, it won't be written when indexing documents, or queried for when searching for them.
In this change, nothing actually writes to the "common" table. I'll start writing to the table in a followup change.
Specifically, I plan to do this:
- A new GC process updates the "common" table periodically, by writing ngrams which appear in more than X% of documents to it, for some value of X, if there are at least a minimum number of documents (maybe like 4,000).
- A new GC process deletes ngrams that have been added to the common table from the existing indexes.
Hopefully, this will pare down the ngrams index to something reasonable over time without requiring any manual tuning.

- Manually inserted ngrams `xxx` and `yyy` into the ngrams table, searched and indexed, saw them ignored as viable ngrams for search/index.

Summary:
Ref T12987. I was focused on the RefCursor table and overlooked that we need some care on this key.
It's currently possible to run `bin/storage upgrade --no-adjust`, then start Phabricator, and end up with duplicate records in this table. If you try to run `bin/storage adjust` later, it will try to add the unique key but fail. This is unusual for normal installs (they usually do not use `--no-adjust`) but we do it in the cluster and I did this exact thing on `secure`.
Normally, to avoid this, when a new table with a unique key is introduced, we also add a migration to explicitly add that key.
This is mostly harmless in this case. Fix this mistake (force the table to contain only unique rows; add the key) and try using `LOCK TABLES` to make this atomic. If this doesn't cause problems we can use this in similar situations in the future.
The "alter table may unlock things" warning comes from here:
https://dev.mysql.com/doc/refman/5.7/en/lock-tables.html
It seems like it's fine to issue `UNLOCK TABLES` even if you don't have any locks, so I think this script should always do the right thing now, regardless of ALTER TABLE unlocking or not unlocking tables.
Test Plan: Ran `bin/storage upgrade -f`, saw table end up in the right state. I'll also check this on `secure`, where the starting state is a little messier.

Summary:
Ref T11823. This change isn't standalone, but prepares for the more involved code change by dropping obsolete columns from the RefCursor table and adding the unique key we need to prevent the ambiguous/duplicate refs issue.
This data was moved to the RefPosition table in D18612.
Test Plan: Ran storage upgrade. See next revision for more substantial testing of this change series.

Summary:
Ref T11823. This populates the new RefPosition table based on the existing RefCursor table, and deletes now-duplicate rows in the RefCursor table so the next change can add a unique key.
This change is not standalone, and there need to be separate code updates. I have a rough version of that written, but this migration needs to happen first to test it.
I'll hold this whole series of changes until after the release cut and until the code is updated.
Test Plan: Ran migration, spot-checked database tables. Saw redundant rows remove and correct-looking rows populated into the new RefPosition table.
