Summary:
After D5245416 I was taking a closer look and decided it's best to get rid of the `Interprocedural` module altogether.
Since jeremydubreil's refactoring to pass the summaries around everywhere, this module doesn't do much (it used to make sure the summary actually got stored to disk).
Client code is shorter and simpler without this module.

Summary:
Only one instance will win in the end so it's not useful to double register.
Log when that happens. Currently it happens in the Java tests on
`InferBuiltins` but I don't understand why so I left it alone.

Summary:
This avoids race conditions when two processes or more try to lock a file for
writing. It could be that the process losing the race writes less than the
winner, then we get rubbish at the end of the file. Calling `ftruncate(2)` inside the critical section makes sure the
contents of the file are erased first. The harmful race was observed in
xcodebuild sometimes, as it can call infer on the same file several times in
parallel (!).

Summary: The docs for this said that it stores the summary to disk, which is no longer true. `compute_summary` is more descriptive of what it actually does now.

Summary: We had a model for `Pools.SimplePool`, but were missing models for `Pools.Pool`. Since `SimplePool` and `SynchronizedPool` both extend `Pool`, modeling it should cover all of the cases.

Summary:
The ThreadSafety analysis currently reports on methods only if some
class in the file defining the method is annotated ThreadSafe, or
if it is called by some other such method call. Conflating files and
classes is a bit of a Javaism that seems to be unnecessary.

Summary:
Now that we can run several inter-procedural analyses at the same time, we should no longer use the function `Reporting.log_error_deprecated` as it logs the errors in the specs table. This specs table is normally used for caching and will be deprecated in favor of having a cache summaries for the callees in the `Ondemand` module (to avoid deserialising a callee more than once within the same process).
This revision just renames the reporting functions.

Summary:
Read/write race errors should always show one trace for a read and one trace for a write.
We forget to pass the conflicting writes to the reporting function in one case, which prevented us from showing a well-formed trace.
Fixed it by making the `conflicts` parameter non-optional

Summary:
This messes up with the Buck cache: if infer recaptures a file with only trivial changes that shouldn't affect the capture Buck will still believe it has to reanalyze everything that depends on that file if there's non-deterministic data in infer's output.
Re-use the `--buck` flag used by the Java Buck integration for mostly the same purposes. Add a few special cases for the flavours integration (eg: keep capture data).
Change perf stats registration to take `Config.buck_cache_mode` into account instead of relying on each call site to handle that peculiarity correctly. Also, there's no need to create the perf stats directories before calling the registration function since it will do that too.

Summary:
It is not used, so one fewer thing to track inside Python.
Note that Python does pass `--buck` to OCaml infer to make it aware that it is
running from within Buck, and the OCaml code uses that flag to trim infer-out
to only what's strictly necessary (and especially to remove non-deterministic
output that would mess with Buck's cache).
