Summary:
Even with `innodb_file_per_table` enabled, individual table files on disk don't normally shrink.
For most tables, like `maniphest_task`, this is fine, since the data in the table normally never shrinks, or only shinks a tiny amount.
However, some tables (like the "worker" and "daemon" tables) grow very large during a huge import but most of the data is later deleted by garbage collection. In these cases, this lost space can be reclaimed by running `OPTIMIZE TABLE` on the tables.
Add a script to `OPTIMIZE TABLE` every table.
My primary goal here is just to reduce storage pressure on `db001` since there are a couple of "import the linux kernel" installs on that host wasting a bunch of space. We're not in any trouble, but this should buy us a good chunk of headroom.
Test Plan: Ran `bin/storage optimize` locally and manually ran `OPTIMIZE TABLE` in production, saw tables get optimized.

Summary:
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.

Ref T12470. This helps defuse attacks where an adversary can directly take control of whatever storage engine files are being stored in and change data there. These attacks would require a significant level of access.
Such attackers could potentially attack ranges of AES-256-CBC encrypted files by using Phabricator as a decryption oracle if they were also able to compromise a Phabricator account with read access to the files.
By storing a hash of the data (and, in the case of AES-256-CBC files, the IV) when we write files, and verifying it before we decrypt or read them, we can detect and prevent this kind of tampering.
This also helps detect mundane corruption and integrity issues.

Specifically, this is the case where we get into trouble:
- I upload a private file with content "X".
- You somehow generate a file with the same content by, say, viewing a raw diff in Differential.
- If the diff had the same content, you get my file, but you don't have permission to see it or whatever so everything breaks and is terrible.

Summary:
Ref T11357. When creating a file, callers can currently specify a `ttl`. However, it isn't unambiguous what you're supposed to pass, and some callers get it wrong.
For example, to mean "this file expires in 60 minutes", you might pass either of these:
- `time() + phutil_units('60 minutes in seconds')`
- `phutil_units('60 minutes in seconds')`
The former means "60 minutes from now". The latter means "1 AM, January 1, 1970". In practice, because the GC normally runs only once every four hours (at least, until recently), and all the bad TTLs are cases where files are normally accessed immediately, these 1970 TTLs didn't cause any real problems.
Split `ttl` into `ttl.relative` and `ttl.absolute`, and make sure the values are sane. Then correct all callers, and simplify out the `time()` calls where possible to make switching to `PhabricatorTime` easier.

Also, make "no writable services are configured" acceptable, rather than an error.

However, this version doesn't consider "cluster.search" configuration, so if you add a new service (like a new ElasticSearch host) we still think that every document is up-to-date. When you run `bin/search index` to populate the index (without `--force`), we just do nothing.
This isn't necessarily very obvious. D17597 makes it more clear, by printing "everything was skipped and nothing happened" at the end.
Here, fix the issue by considering the content of "cluster.search" when computing fulltext document versions: if you change `cluster.search`, we throw away the version index and reindex everything.
This is slightly more work than we need to do, but changes to "cluster.search" are rare and this is much easier than trying to individually track which versions of which documents are in which services, which probably isn't very useful anyway.

- Ran `bin/search index --type project`, saw everything get skipped.
