- rename java.make -> javac.make, config.make -> java.make, and move to infer/tests/ so it's easier to use from infer/tests/build_systems/
- use these from ant's test Makefile, much code reuse!
- factor out common functionality between java and clang
A wrinkle: sorting is now done the same way for --issues-tests and
--issues-txt, which produces bogus (but still as deterministic) sorting for
--issues-txt. This is more of a cosmetic issue, but I hope to fix it in a later

Summary:
Summaries are modified before saving from disk, for example the attributes of the postcondition can change.
I have observed flaky reports of the internal error NULL_TEST_AFTER_DEREFERENCE. Some attributes (e.g. assigned) are changed before saving, but the spec table in memory is not changed.
So in case:
1) the procedure is analyzed on-demand, then subsequent uses in the same process use the summary in memory with the unchanged attribute, and the issue is not reported.
2) the procedure is already on disk and loaded, then the loaded summary has the changed attributes, and the issue is reported.
Flakiness happens as because of parallelism, whether a procedure is analyzed already or whether it is analyzed on-demand, can change.
The normalization function can change the instrumentation of a symbolic heap because it uses the existing comparison functions, which ignore instrumentations.
So normalization can replace part of a symbolic heap with an identical one but where the instrumentation is different — this is what I have observed.
The diff uses a different comparison function where instrumentations are taken into account.

This diff changes recording of sinks so that a sink is now the *last* function in a trace to call a sink.

This new convention will make the `returnAllSources`/`callAllSinks` form of these tests not so useful, since `returnAllSources`/`callAllSinks` will now show up as a single source/sink in the trace (at least without expanding the trace).

Summary: Fix the resolution of symbolic links. The previous version did not work if the path itself was not a symbolic link, but there was a symbolic link somewhere up in the path tree. For example: `path/to/file` where `file` is not a symbolic link, but `to` is a symbolic link.

Summary: This code is an old experiement and has never really be used in prod because it was creating false positive. Dealing static final fields should be done in the backend instead so that it can used by the different languages C, Objective C, C++ and Java.

Also be more careful when escaping arguments and create a module for shared

Summary: Some arguments passed from infer.ml to infer.py were only used to pass further to infer.ml invocations. Those args should be passed by env variable anyway (???)

Summary:
Fix an issue where, when `-reactive` mode is used, files captured in the first second are not considered modified, and are not analyzed. This happens because file timestamps are used, and the resolution is one second.
Change the front-ends to change the timestamp of the directory where artifacts are created, so that the timestamps are 1 second in the future.
Small reactive commands such as the following now analyze correctly:
rm -rf infer-out && infer --reactive -- clang -c test.c

Move compilation database into separate module which loads said database from json file.
It will allow to load database from json file without calling buck.

Summary:
Declared and defined procedure attributes are now saved in different files (hashed_name.decl.attr and hashname.attr).
We always try to load using the filename of defined procedure attributes first,
and fall back to loading the file for declared ones if it does not exist.
The logic for replacing an existing file stays the same, with one extra thing:
when a file for a defined attribute is written, the one for the declared one
is deleted if it exists.
At the end of a capture, either a declared or a defined file exist, but not both.
The reason for this change is that when captures of different subprojects are
merged together, it can happen that a link gets created to a declared attributes
file even though a defined one exists, so the body of the procedure will not be analyzed.
After this diff, both links will be created, and the defined one will be loaded
by the back-end.

Summary:
Python isn't needed anymore to pass options between `infer` and `InferClang`.
However, it is still needed to set up `PATH` so that we pick up compilation
commands.

This also adds `-a compile` support to `InferClang`. This is needed for the
