Summary:
Ref T3775 (discussion here). Ref T2625.
T3775 presents two problems:
# Existing tools which linked to `/differential/active/epriestley/` (that is, put a username in the URL) can't generate search links now.
# Humans can't edit the URL anymore, either.
I think (1) is an actual issue, and this fixes it. I think (2) is pretty fluff, and this doesn't really try to fix it, although it probably improves it.
The fix for (1) is:
- Provide a helper to read a parameter containing either a list of user PHIDs or a list of usernames, so `/?users[]=PHID-USER-xyz` (from a tokenizer) and `/?users=alincoln,htaft` (from an external program) are equivalent inputs.
- Rename all the form parameters to be more digestable (`authorPHIDs` -> `authors`). Almost all of them were in this form already anyway. This just gives us `?users=alincoln` instead of `userPHIDs=alincoln`.
- Inside ApplicationSearch, if a request has no query associated with it but does have query parameters, build a query from the request instead of issuing the user's default query. Basically, this means that `/differential/` runs the default query, while `/differential/?users=x` runs a custom query.

@wez, this changes the Differential revision list UI substantially and may generate a lot of bikeshedding / who-moved-my-cheese churn. See T3417 for context, for example. The motivations for this change are:
- The list now works on devices, like phones and tablets. This is a requirement to make the rest of Differential work on devices.
- Although ApplicationSearch intentionally presents a simpler interface initially and some options which were one click away before aren't now, it is much more powerful than the search it replaces and allows users to build, save, share, fork, edit, and customize a much wider range of queries. Users who used the old filters frequently can use Advanced Search -> Save Custom Query to create new versions of them, and of any other query. "Edit Queries.." allows users to remove and reorder queries, including builtin queries. Basically, there are like three things which have gone from "1-click" to "a few clicks", and ten trillion things which have gone from "hard/impossible" to "relatively easy".
The local screenshots look a bit iffy, but I think a lot of this is the fakenesss of my test data. If they still feel iffy in production we can tweak them until they feel good, like we did for Maniphest.

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.

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.

@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.
