Summary: This way, if infer crashes then the log files will be available for inspection, but if it succeeds we still get rid of the (non-deterministic) logs before Buck caches the results.

Summary:
Fixes 2 issues with the build:
- The OCaml dependencies (Version.ml, atdgen-generated stuff, ...) would be generated twice when running `make -j test` from a clean tree, because `make` has no inter-Makefile visibility over common dependencies.
- We would run `atdgen` twice: once for the .ml, once for the .mli, even though one invocation is enough for both.
Add `make ocaml_clean` to nuke only the OCaml code (in particular because
rebuilding the C++ code in the plugin is slow when all I want to get rid of the
OCaml stuff).

Summary:
First steps towards implementing diff analysis functionalities inside infer
itself. What works: run infer, checkout parent, re-run infer, checkout top
revision, compute the reportdiff (but no final surfacing on the console). Lots
of TODO still, inlined in the code.

Summary:
Allowing the user to configure where to store the JSON report is asking for
trouble. In fact, some places in the code hardcoded "results.json" anyway.
Someone wanting to have results.json somewhere else can still copy report.json
once infer has run.

This reverts commit 7177bb6b8af1404fde408ead4750ef48ed9bdaff.
In practice, `extract_filepath` exhausts the call stack, leading to "RuntimeError: maximum recursion depth exceeded" exceptions. Perhaps a loop needs to be used instead.

Summary:
Problem: The analyzer did not know that the value of `v.size()` is an alias of `v.infer_size`, so `v.infer_size` is not pruned by the if condition. As a result it raises a false alarm.
void safe_access(std::vector<int> v) {
if (v.size() >= 10) {
v[9] = 1; // error: BUFFER_OVERRUN Offset: [9, 9] Size: [5, 5]
}
}
void call_safe_access_Good() {
std::vector<int> v(5, 0);
safe_access(v);
}
Solution: Adding alias for return value to the abstract domain.
Now Inferbo can prune `v.infer_size` because it knows that the value of `v.size()` is an alias of `v.infer_size`. There is already an alias domain in Inferbo, so we added a specific room for the retrun value.

Summary:
1. Allow it to forward -version calls to javac (so that if the build system wants
to check the compiler version it doesn't end up with Infer's version)
2. Preserve empty arguments:
javac -bootclasspath "" -classpath a.jar ...
currently gives:
javac: invalid flag: a.jar

Conversion and reformat of infer source using ocamlformat
auto-formatting tool.
Current status:
- Because Reason does not handle docstrings, the output of the
conversion is not 'Warning 50'-clean, meaning that there are
docstrings with ambiguous placement. I'll need to manually fix
them just before landing.

Summary:
The thread safety domain manipulates access paths that are a variable
followed by a sequence of field or index accesses. Some expressions
from C++ code do not fit that form, such as cases where subtraction of
an offset from a pointer is used to obtain another pointer, whose
fields are then accessed. Previously the analyzer would crash on such
expressions. This diff partially treats them by introducing dummy
variables.
