Summary:
Maintain an "ownership" set of access paths that hold locally allocated memory that has not escaped.
This memory is owned by the current procedure, so modifying it outside of synchronization is safe.
If an owned access path does escape to another procedure, we remove it from the ownership set.

Summary:
Although the Builder pattern is not actually thread-safe, Builder's are not expected to be shared between threads.
Handle this by ignoring all unprotected accesses in classes the end with "Builder".
We might be able to soften this heuristic in the future by ensuring rather than assuming that Builder are not shared between methods (or, ideally, between threads).

Summary:
`o.<init>` cannot be called in parallel with other methods of `o` from outside, so it's less likely to have thread safety violations in `o.<init>`.
This diff suppresses reporting of thread safety violations for fields touched (transitively) by a constructor.
We can do better than this in the future (t14842325).

Summary:
Before, we were using a set domain of strings to model a boolean domain.
An explicit boolean domain makes it a bit clear what's going on.
There are two things to note here:
(1) This actually changed the semantics from the old set domain. The set domain wouldn't warn if the lock is held on only one side of a branch, which isn't what we want.
(2) We can't actually test this because the modeling for `Lock.lock()` etc doesn't work :(.
The reason is that the models (which do things like adding attributes for `Lock.lock`) are analyzed for Infer, but not for the checkers.
We'll have to add separate models for thread safety.

Summary:
Record an abstraction of the bug traces in the tests. The abstraction of a
trace is the sequence of descriptions. In practice, descriptions are either
empty, or of the form "start/end/return from/call to procedure X". They seem
pretty stable.
Motivation: there is nothing testing the traces reported by Infer right now,
even though they are surfaced to developers. For instance, Quandary uses
--issues-txt instead of --issues-tests to make sure the traces do not regress.
This change would make this approach more widespread.

When loading results from a json file, sort them. This prints results in some
