Summary:
Ref T9979. This uses ngrams (specifically, trigrams) to build a reasonably efficient index for substring matching. Specifically, for a package like "Example", with ID 123, we store rows like this:
```
< ex, 123>
<exa, 123>
<xam, 123>
<amp, 123>
<mpl, 123>
<ple, 123>
<le , 123>
```
When the user searches for `exam`, we join this table for packages with tokens `exa` and `xam`. MySQL can do this a lot more efficiently than it can process a `LIKE "%exam%"` query against a huge table.
When the user searches for a one-letter or two-letter string, we only search the beginnings of words. This is probably what they want, the only thing we can do quickly, and a reasonable/expected behavior for typeaheads.
Test Plan:
- Ran storage upgrades and search indexer.
- Searched for stuff with "name contains".
- Used typehaead and got sensible results.
- Searched for `aabbccddeeffgghhiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz` and saw only 16 joins.

Summary:
Fixes T9890. This allows IndexExtensions to emit an object version.
Before we build indexes, we check if the indexed version is the same as the current version. If it is, we just don't call that extension.
T9890 has a case where this is useful: a script went crazy and posted thousands of comments to a single task.
Without versioning, that results in the same comments being indexed over and over again. With versioning, most of the queue could just exit without doing any work.
Test Plan:
- Added a `sleep(1)` to the actual indexing, used `bin/search index --background` to queue up a lot of tasks, ran them with `bin/phd debug task`, saw them complete very quickly with only one actual index operation performed.
- Used `bin/search index --trace` and `bin/search index --trace --background` to observe the behavior of queries against the index version store, which looked sensible.
- Made comments/transactions, saw versions update.
- Used `bin/remove destroy`, verified index versions were purged.

Summary:
Ref T9964. We have various kinds of secondary data on objects (like subscribers, projects, paste content, Owners paths, file attachments, etc) which is somewhat slow, or somewhat large, or both.
Some approaches to handling this in the API include:
- Always return all of it (very easy, but slow).
- Require users to make separate API calls to get each piece of data (very simple, but inefficient and really cumbersome to use).
- Implement a hierarchical query language like GraphQL (powerful, but very complex).
- Kind of mix-and-match a half-power query language and some extra calls? (fairly simple, not too terrible?)
We currently mix-and-match internally, with `->needStuff(true)`. This is not a general-purpose, full-power graph query language like GraphQL, and it occasionally does limit us.
For example, there is no way to do this sort of thing:
$conpherence_thread_query = id(new ConpherenceThreadQuery())
->setViewer($viewer)
// ...
->setNeedMessages(true)
->setWhenYouLoadTheMessagesTheyNeedProfilePictures(true);
However, we almost never actually need to do this and when we do want to do it we usually don't //really// want to do it, so I don't think this is a major limit to the practical power of the system for the kinds of things we really want to do with it.
Put another way, we have a lot of 1-level hierarchical queries (get pictures or repositories or projects or files or content for these objects) but few-to-no 2+ level queries (get files for these objects, then get all the projects for those files).
So even though 1-level hierarchies are not a beautiful, general-purpose, fully-abstract system, they've worked well so far in practice and I'm comfortable moving forward with them in the API.
If we do need N-level queries in the future, there is no technical reason we can't put GraphQL (or something similar) on top of this eventually, and this would represent a solid step toward that. However, I suspect we'll never need them.
Upshot: I'm pretty happy with "->needX()" for all practical purposes, so this is just adding a way to say "->needX()" to the API.
Specifically, you say:
```
{
"attachments": {
"subscribers": true,
}
}
```
...and get back subscriber data. In the future (or for certain attachments), `true` might become a dictionary of extra parameters, if necessary, and could do so without breaking the API.
Test Plan:
- Ran queries to get attachments.

- Don't load named queries multiple times on search pages.
- Don't require extra code to get standard navigation right on mobile.
- Reduce the amount of boilerplate in ListControllers.
- Reduce the amount of boilerplate around navigation/menus in all controllers.
Specifically, here's what this does:
- The StandardPage is now a smarter/more structured object with `setNavigation()` and `setCrumbs()` methods. More rendering decisions are delayed until the last possible moment.
- It uses this to automatically add crumb actions to the application menu.
- It uses this to automatically reuse one SearchEngine instead of running queries multiple times.
- The new preferred way to build responses is `$this->newPage()` (like `$this->newDialog()`), which has structured methods for adding stuff (`setTitle()`, etc).
- SearchEngine exposes a new convenience method so you don't have to do all the controller delegation stuff.
- Building menus is generally simpler.
Test Plan:
- Tested paste list, view, edit, comment, raw controllers for functionality, mobile menu, crumbs, navigation menu.
- Edited saved queries.
