Summary:
This diff revises the makefiles for java tests so that they are based on
the files actually produced and depended on, instead of the existing
imperative style. This is, I think, clearer and easier to modify, and
enables a little more parallelism.

Summary: The lazy dynamic dispatch algorithm works by re-analyzing the generic methods with the more specialized types encountered during the symbolic execution. In order to do that, the analysis must access the procedure description of the method to reanalyze in order to run the analysis of the specialized procedure description on demand. This diff adds the procedure description on the summary as the summary are stored in the Buck cache and can easily be retrieved by procname.

Summary:
- do a semantic analysis of each variable initializer to figure out if they need initialization
- add a flag to globals that is true when they are `constexpr`. In that case, no analysis is needed as the user + compile guarantee that it is a compile-time constant.

Summary: The direct test rules are very regular and depend only on their names, except for some *_infer_* rules that I had to change to *_errors_*. We can rename these directories if we want (to make them like Java).

1. `--version` never makes it to infer.py

Summary:
Right now, taint gets lost if it flows into a constructor or procedure whose implementation is missing.
Since the core Java (e.g., String) and Android classes (e.g, Intent) are among these, this is bad.
We could handle this by writing a bunch of models instead, but that would be a lot of work (plus we may still miss cases).

Summary:
Merging the results directories of targets on buck projects involved creating symbolic links into buck-out.
The bulk of files are .attr files: one per procedure. Creating these links can be a bottleneck, and the merge phase can be slower than the analysis phases on projects with many procedures.
This diff introduces multilinks to speed up merge.
A multilink is a file `multilink.txt` containing a sequence of paths
```
path/to/file1.ext
path/to/file2.ext
...
```
A multilink file is a compact way to represent a link for each entry.
This diff creates a multilink file for each `attributes/dir` directory, instead of one symbolic link for each file.

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
