Summary:
Buck reads the version on stderr or, very recently, from either stdout or stderr.
This makes infer output the version of stderr when called from Buck or invoked as javac, and on stdout otherwise.

Summary:
Whenever we see a use of a lock, infer that the current method can run in a multithreaded context. But only report when there's a write under a lock that can be read or written without synchronization elsewhere.
For now, we only infer this based on the direct usage of a lock; we don't assume a caller runs in a multithreaded context just because its (transitive) callee can.
We can work on that trickier case later, and we can work on smarter inference that takes reads under sync into account. But for now, warning on unprotected writes of reads that occur under sync appears to be too noisy.

Summary:
This will allow most of the checkers, except the bi-abduction, to skip the analysis on the specialized clone of the methods used to handle dynamic dispatch. Doing this, we can run the bi-abduction analysis using:
infer -a checkers --biabduction
without risk of conflicts on the resolution of dynamic dispatch.

Summary:
It looks like the old code for expanding access paths assumed that `FormalMap.get_formals_indexes` assumed the returned list tuples would be sorted by index, but it's actually sorted by var name.
As a consequence, formals might be expanded into the wrong actuals.
This diff fixes the problem by not relying on `get_formals_indexes`.

This was a crutch from the days before ownership analysis.

Summary:
One day `-a infer` will alias `-a checkers` so for now create another, more
explicit analyzer name that can be used to migrate progressively. For instance,
after this commit what should continue to use `-a biabduction` can change to
that, so that when `-a infer` becomes an alias to `-a checkers` it can keep
working.

Summary:
9c7fc65 introduced a large performance regression, this diff eliminates it and a bit more.
Instead of constructing the quotiented access list map in a two-step process of first constructing a map of all accesses and then quotienting it, the quotiented map is constructed directly by using a coarser comparison function on keys. Partitioning the access map O(number of access paths) times, using an apparently expensive partition predicate, seems to be causing trouble based on rough profile data.
