Summary:
Ref T603. Ref T2625. Use cursors to page Differential queries, not offsets.
The trick here is that some queries are ordered. In these cases, we either need to pass some kind of tuple or do a cursor lookup. For example, if you are viewing revisions ordered by `dateModified`, we can either have the next page be something like:
?afterDateModified=2398329373&afterID=292&order=modified
...or some magical token:
?afterToken=2398329373:292&order=modified
I think we did this in Conpherence, but one factor there was that paging orders update with some frequency. In most cases, I think it's reasonable to pass just the ID and do a lookup to get the actual clause value (e.g., go look up object ID 292 and see what its dateModified is) and I think this is much simpler in general.
Test Plan: Set page size in Differential to 3, and paged through result lists ordered by date created and date modified.

Summary:
Currently, when querying for responsible users (revisions where a given user is either the author or a reviewer), we do this:
- If the query passes a bunch of hard-coded special cases, use a special hard-coded UNION.
- Otherwise, use a very complicated JOIN/WHERE clause.
This is bad for several reasons:
- Tons and tons of hard-coding and special casing.
- The JOIN/WHERE clause performs very poorly for large datasets.
- (As a material consequence, the homepage issues a responsible query which barely misses the hard-coded special cases and goes down the slow path.)
Instead, //always// use the UNION strategy to execute a "responsible" query. Specifically, if we have responsible PHIDs, temporarily add them to the author list and build a normal query, then repeat for reviewers, then UNION any clauses we built.
Fixes T3377. Ref T603. Ref T2625. Depends on D6342.
There's various folklore about UNION ALL / UNION DISTINCT performance. UNION DISTINCT is simpler here and the number of rows is small, although we could use UNION ALL in the form:
SELECT * FROM ((SELECT ...) UNION ALL (SELECT ...) ORDER) GROUP LIMIT
...if we find that there's some performance benefit at some point.
Test Plan: Used DarkConsole to examine queries. Viewed home page and Differential dashboard/authors/subscribers.

Summary:
Ref T2222.
I'm thinking about how I want to approach the Asana sync, and I want to try to do T2222 first so that we can build it cleanly on top of ApplicationTransactions. I think we can at least walk down this road a little bit and if it turns out to be scary we can take another approach.
I was generally very happy with how the auth migration turned out (seemingly, it was almost completely clean), and want to pursue a similar strategy here. Basically:
- Wrap the new objects in the old objects for reads/writes.
- Migrate all the existing data to the new table.
- Everything hard is done; move things over a piece at a time at a leisurely pace in lots of smallish, relatively-easy-to-understand changes.
This deletes or abstracts all reads of the DifferentialComment table. In particular, these things are **deleted**:
- The script `undo_commits.php`, which I haven't pointed anyone at in a very long time.
- The `differential.getrevisionfeedback` Conduit method, which has been marked deprecated for a year or more.
- The `/stats/` interface in Differential, which should be rebuilt on Fact and has never been exposed in the UI. It does a ton of joins and such which are prohibitively difficult to migrate.
This leaves a small number of reading interfaces, which I replaced with a new `DifferentialCommentQuery`. Some future change will make this actually load transactions and wrap them with DifferentialComment interfaces.

- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.

@nh / @jungejason / @aran, can one of you run some queries agianst FB's corpus?
The "active revisions" view is built much differently now. Before, we issued two
queries:
- SELECT (open revisions you authored that need revision) UNION ALL (open
revisions you are reviewing that need review)
- SELECT (open revisions you authored that need review) UNION ALL (open
revisions you are reviewing that need revision)
These two queries generate the "Action Required" and "Waiting on Others" views,
and are available in P247.
Now, we issue only one query:
- SELECT (open revisions you authored or are reviewing)
Then we divide them into the two tables in PHP. That query is available in P246.
On the secure.phabricator.com data, this new approach seems to be much better
(like, 10x better). But the secure.phabricator.com data isn't very large. Can
someone run it against Facebook's data (using a few heavy-hitting PHIDs, like
ola or something) to make sure it won't cause a regression?
In particular:
- Run the queries and make sure the new version doesn't take too long.
- Run the queries with EXPLAIN and give me the output maybe?
Test Plan:
- Looked at different filters.
- Changed "View User" PHID.
- Changed open/all.
- Changed sort order.
- Ran EXPLAIN / select against secure.phabricator.com corpus.

Summary:

- Add the ability to query for "subscribers" (reviewer or CC).
- Fix an issue where CC and Reviewer used the same join table alias and were
incompatible.
- Remove support for 'paths' for the moment, since each path needs a
repository ID. (There are no clients for this.)
- Remove single withX() methods that have no callsites -- withPath() is
singular because it accepts two arguments and I didn't want to have an ad-hoc
type format, but I think we can get away without these for other conditions.
- Include GROUP BY in more cases where may need it. This doesn't actually
change program behavior since we uniquify in loadFromArray(), it just means less
data over the wire.
These new query classes are to support rewriting the Differential list view on
top of DifferentialRevisionQuery.

- Issued queries via conduit for "responsible users".
- Issued queries via conduit for "subscribers".
- Issued queries via conduit for "cc" with "reviewer" at the same time.
- Issued queries via conduit for "cc", "reviewer", "responsible users" and
