Summary:
This diff unifies the --specs-library and --zip-specs-library options,
delaying the point where their relative order gets lost to at least
after option parsing. This also moves the treatment of non-cached jar
libraries from Config to where they are used in ZipLib. The
implementation of expanding the cached jars is slightly simplified and
untangled from option parsing.

Summary:
this makes frontends no longer depend on SymExec.ml. `ModelBuiltins` was split into two modules:
- `BuiltinDecl` with procnames for builtins (used to determine whether some function is a builtin)
- `BuiltinDefn` with implementations used by `SymExec`
- they both have similar type defined in `BUILTINS.S` which makes sure that new builtin gets added into both modules.
During the refactor I ran some scripts:
`BuiltinDecl.ml`:
let X = create_procname "X"
cat BuiltinDecl.ml | grep "create_procname" | tail -70 | awk ' { print $1,$2,$3,$4,"\42"$2"\42"} '
then manually confirm string match. Exceptions:
"__exit" -> "_exit"
"objc_cpp_throw" -> "__infer_objc_cpp_throw"
__objc_dictionary_literal
nsArray_arrayWithObjects
nsArray_arrayWithObjectsCount
`BuiltinDefn.ml`:
let X = Builtin.register BuiltinDecl.X execute_X
cat BuiltinDecl.ml | grep "create_procname" | tail -70 | awk ' { print $1,$2,$3,"Builtin.register BuiltinDecl."$2,"execute_"$2} '
then, fix all compilation problems

Summary:
InferClang knows what to do if its name ends in ++. So it is not
necessary to pass whether or not the original clang executable ended in
++ to InferClang using the the INFER_XX environment variable. Instead,
create an InferClang++ symbolic link and make the clang wrapper call
either InferClang or InferClang++ as needed.

We issue a thread safety warning on a class not

it will be nice to remind that a super is so maeked, else the mesg could

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:
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.
