Fixes T5840. Some time ago I incorrectly believed that `latin1_bin` collation was synonymous with "binary". It is not, and does not permit UTF8 characters outside of BMP, among other sequences.
These two tables currently have `LONGTEXT` columns which should be `LONGBLOB`. The table design is explicilty intended to accommodate invalid/unreasonably long ref names, but the collation prevents this from working properly.
After T1191, we'll have a general system for resolving this, but a user hit an issue yesterday (T5840) with a brnach name containing Chinese characters.

Fixes T5837. The problem is that the hash is being recognized as a commit hash. We currently fire the object monogram rules fairly early, but there's no real reason to do this. Move them after all of the hyperlink rules:

150 PhutilRemarkupDocumentLinkRule
175 PhrictionRemarkupRule

- The disadvantage of this approach is that `{F123, alt=go look at http://lol.com/ omg}` will parse the URL first, and then fail to resolve the object embed. This seems very rare / unusual.
- The advantage is that all URLs which happen to have monograms in them work.
In the future, we could refine this by separating the rules, so the embed (`{...}`) versions fired at priority 200, while the normal versions fired at priority 450. We can wait for use cases, though. This is a little messy because the same code implements both rules.
Test Plan:
- Verified example in T5837.
- Marked up object rules like `F123` (works), `[[ asdf | F123 ]]` (works), `{F123, alt=http://example.com}` (does not work).

Summary:
Via HackerOne. If a user adds an email address and typos it, entering `alinculne@gmailo.com`, and it happens to be a valid address which an evil user controls, the evil user can request a password reset and compromise the account.
This strains the imagination, but we can implement a better behavior cheaply.
- If an account has any verified addresses, only send to verified addresses.
- If an account has no verified addresses (e.g., is a new account), send to any address.
We've also received several reports about reset links not being destroyed as aggressively as researchers expect. While there's no specific scenario where this does any harm, revoke all outstanding reset tokens when a reset link is used to improve the signal/noise ratio of the reporting channel.
Test Plan:
- Tried to send a reset link to an unverified address on an account with a verified address (got new error).
- Tried to send a reset link to a verified adddress on an account with a verified address (got email).
- Tried to send a reset link to an invalid address (got old error).
- Tried to send a reset link to an unverified address on an account with only unverified addresses -- a new user (got email).
- Requested several reset links, used one, verified all the others were revoked.

Summary:
- Fixes T5851. Currently, if a commit has `Fixes T123`, we generate an email with just that before generating the commit email. Don't send/publish transactions about a commit before it imports (this is a tiny bit hacky, but well-contained and I don't think it causes any problems).
- Fixes T4864. Currently, we try to parse Differential information even if Differential is not installed. Instead, do this only if Differential is installed.
- Fixes T5771. Currently, if we can't figure out who the committer/author of a commit is, we don't publish a `Fixes T123` transaction. Instead, fall back to acting as "Diffusion" if we can't find a better actor. Most of this diff expands the role of application actors. The existing application actors (Herald and Harbormaster) seem to be working well.
Test Plan:
- Pushed a commit with `Fixes T123` and verified it did not generate email directly. (The task half of the transaction still does, correctly.)
- Uninstalled Differential and pushed a commit, got a clean import instead of an exception.
- Commented out author/committer PHIDs and pushed stuff, saw a "Diffusion" actor.

Summary:
Ref T5685. Currently we just 403 on an invalid token, but we can be a little more helpful.
The issues here are:
- If we **do** redirect you on this page and something goes wrong, you might get stuck in a redirect loop.
- If we **don't** redirect you, copy/pasting the link to someone (or reloading the page) gives them a pretty confusing result, since the link doesn't work any more. Prior to this diff, they get a 403.
To mitigate this, do a little better than a bare 403: give them a link to auth and generate a new URI for the file.
If this is still confusing, the next best thing I can come up with is something like this:
- Put some modulous of the timestamp in the URI.
- If the current time is within 2 seconds of the generation time, show this dialog.
- Otherwise, redirect.
That seems like it would be okay, but I worry that "2" has to be small (so links you copy/paste -> chat -> click still work) and a small value means that a small amount of clock skew breaks things. We could use the database clock, but ehhh.
Other ideas:
- Put a hash of the remote IP in the URI, redirect if it doesn't match. Fails for companies behind a NAT gateway but should work in a lot of other cases.
- Just redirect always, there's no reason it should ever loop and browsers don't really do anything bad when there's a loop (they'll show an error after too many redirects).
I'm leaning toward letting this stabilize in the wild for a bit, then trying "always redirect".

Fixes T5770. This error occurs if you run `bin/storage upgrade` before you set up MySQL credentials.
This isn't what the setup guide says to do, but it's an easy mistake to make and should be a permitted install path since there's no reason you can't do things in this order.
Specifically, we use a mixture of "standard" (configured) and "administrative" (`--user` and `--password`) credentials, and if the standard ones are bogus bad things happen. We use the standard credentials to make some initialization order stuff easier, and because there's no `--host` flag and adding one would be silly, and because we only need administrative credentials to issue ALTER / CREATE statements.

Summary:
Ref T4807. This is an alternative to D10179. The problem these diffs solve is that I want to be able to reorder a column's positions without having to load the actual objects, but that's difficutl because two positions may have the same sequence number (and I think it's good that we allow that, since it makes a bunch of other stuff way easier).
Instead of using the object ID (e.g., the task ID) to reorder positions with the same sequence, use the position itself. This is a little easier, is less ambiguous if columns eventually have several types of objects, and produces a better behavior when old objects are freshly added to a board. For example, if you tag `T300` with `#project`, this new rule will push it to the top of "Backlog" while the old rule might have buried it deep. I think this behavior is desirable and more "natural".
When creating a group of new rows, we do order the batch by ID, so a group of freshly-tagged objects float to the top togehter in ID order. This seems like the most natural rule, too.
Test Plan:
- Loaded some boards with implicit objects on them (freshly tagged tasks) and saw rows create.
- Verified new rows created in the right order.
- Dragged some tasks around.
