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).

Summary:
Mutating a formatter in `dup_formatter` had unintended consequences of
double-printing newlines. There's actually no need not to make a fresh copy,
which avoids this problem.
Also, don't warn if the log file is still a buffer at the end of execution as
that can happen in some error cases, eg:
```
$ infer -- build
ERROR: (Invalid_argument "Unsupported build command build")
```

Summary:
First step toward addressing bad traces that happen in examples like
```
void sourceMethod() {
Obj source = (Obj) InferTaint.inferSecretSource();
callSameSink(null, source); // index: 1
}
void callSameSink(Obj o1, Obj o2) {
callMySink1(o1); // flows via o1 ~= index 0, don't expand
callMySink2(o2); // flows via o2 ~= index 1, can expand
}
void callMySink1(Obj o) {
... // maybe interesting something happens here that doesn't happen in callMySink2
InferTaint.inferSensitiveSink(o); // flows via o ~= index 0, can expand
}
void callMySink2(Obj o) {
InferTaint.inferSensitiveSink(o); // flows via o ~= index 0, can expand
}
```
The issue is that when we recreate a trace to the sink starting from `sourceMethod`, we don't know which of the calls to `callMySink` to expand/include in the trace.
If we expand the call to `callMySink(o1)`, we'll get a bogus trace.
In this example that's not such a big deal, but imagine the case where the first call to `callMySink` is a different function that transitively calls the sink through some long and confusing path.
Remembering the index at which taint flows into each sink will let us choose which sinks are safe to expand.
This diff just adds indexes to the API; it's not actually propagating the index info or using it during expansion yet.
