Ref T10010. Subprojects have the following general membership rule: if you are a member of a subproject ("Engineering > Backend"), you are also a member of the parent project.
It would be unreasonably difficult to implement this rule directly in SQL when querying `withMemberPHIDs()`, because we'd have to do an arbitrarily large number of arbitrarily deep joins, or fetch and then requery a lot of data.
Instead, introduce "materailized members", which are just a copy of all the effective members of a project. When a subproject has a membership change, we go recompute the effective membership of all the parent projects. Then we can just JOIN to satisfy `withMemberPHIDs()`.
Having this process avialable will also be useful in the future, when a project's membership might be defined by some external source.
Also make milestones mostly work like we'd expect them to with respect to membership and visibility.

I needed to revise the "extended policy check" cycle detection rules. When, e.g., querying a grandchild, they incorrectly detected a cycle because both the child and grandchild needed to check the policy of the grandparent.
Instead, simplify it to just do a basic runaway calldepth check. There are many other safety mechanisms to make it so this can't ever occur.

<exa, 123>
<xam, 123>
<amp, 123>
<mpl, 123>
<ple, 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.

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.
