Summary:public
It could happen that the modification times of symbolic links and
original files checked by reactive mode could be exactly the same. In
this case, some files would perpetually be re-analyzed.
This diff creates symlinks and sets their accessed and modified times
to 1 second in the future so that strict timestamp checking is robust.

This create `make install` and `make uninstall` targets that can be used to
install Infer on a system. All the files needed are installed under
"/usr/local/lib/infer" (by default, but can be configured with ./configure
flags as usual), pretty much like their git infer/ counterparts. Moreover,
"infer" and "inferTraceBugs" are installed in /usr/local/bin (similarly
configurable).
As a bonus, `opam install infer` and `opam remove infer` now work. To use
these, it's better to pin the git repo with "-k git":
cd ~/infer/ # where the repo is
opam pin add -k git --yes infer .
The reason is that otherwise, and only if the repo is not clean, opam will
convert symlinks into regular files, which is not good (compilation will fail).

Eradicate need the procedure attributes for callees.
It relies on the java front-end to create proc descs for callees that are declared but not defined.
This diff remove that needs, and when a callee without prodedure attributes is found, it creates one on the fly. The attribute created is similar to what the Java front-end would do, except
that the number and types of arguments are part of the call instruction, so they can
be used to create the formal parameters.

Summary:public
In Python 2, `shutil.rmtree()`, `os.walk()`, `os.path.join()`, etc. are not
happy when the locale cannot decode the filenames they have to deal with.
Decrease the likelihood of this happening by making the file names generated by
infer ascii-only.
Also ignore character decoding errors optimistically when reading the json
report file.
Add tests that we are able to run the analysis and report the bug on a function
with a utf8 name, and that we are able to remove the previous results
directory.

Summary:public
The option -merge_captured specifies that this is merging the results of capture
using the buck integration. The file specifying the targets is read from `infer-out/infer-deps.txt`.
Each dependency specifies a path in buck-out for one target:
where the results directory after capture is.
The option triggers a merge of the results directories into infer-out.
The merge consists in making a virtual copy, where each file in a
target in `buck-out` gets virtually copied into infer-out by making
one symbolic link per file.
There is a mechanism to detect when the capture of a target has already
been copied: when each source file already exists at the destination.
There's also an option `-modified_targets modified_targets.txt`.
If a target is listed in `modified_targets.txt`, this will force a new creation of links
for that target, whether those links exist or not.

Before this diff, the Java frontend was not adding the definition of the inherited interfaces to the type environment, thus failing to answer questions like "does type X implements Closeable".

Generalize command line option parsing to query an environment variable
for args, and then parse the environment and command line arguments.
Each executable uses a distinct environment variable:
- InferAnalyze: INFER_ARGS
- InferJava: INFERJAVA_ARGS
- InferClang: INFERCLANG_ARGS
- InferLLVM: INFERLLVM_ARGS
- checkCopyright: CHECKCOPYRIGHT_ARGS
For now these variables need to be set manually. So the usability is
still pretty bad, but is a step in the direction of enabling debugging

Summary:public
Assert false have been observed in Procname when analyzing some C projects.
This diff changes the Procname API to make it safe for Java: the java functions in the module don't assert false now. This takes care of the errors observed in C projects.
The new API forces changes throughout the codebase. In particular, the constant propagation module was making assumptions that it would only be executed on Java code, triggering assert false on C. Now it is safe.
For the remaining functions in the Procname module, those for other languages, a special assert false in Utils is used to print stack traces. This is for future debugging.
