Instead of translating code from headers blindly, translate only gets transitively referenced from source code.
It won't translate functions from system headers, but in the future we could do that as well
since most of them aren't used and it shouldn't add much overhead.
For now this functionality is hidden behind --cxx-experimental flag

Instead of using location of init_stmt, use location of variable when translating initialization.
Most of the time it change anything with some exceptions:
// example1 - C/C++/objC
int x = // now: assignment happens in this line
3; // past: assignment happens in this line
// example2: valid in C++11 only
struct X {
int x = 0; // now: one assignment here
int y = 2; // now: one assigmnent here
X() = default; // before: 2 assignments in this line
};

Simplifies the way to configure cmake to run infer's fake compiler commands.
Instead of `CC=/path/to/infer/infer/lib/capture/clang cmake .`, which is what
is advised on #25 and is now outdated because the paths to infer's clang has
changed since, simply run `infer -- cmake .`. The only caveat is that infer
tries to analyze the end result, and prints "No issues found". This could be
fixed later.

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.

Create a model of std::unique_ptr in similar fashion to what was done to std::shared_ptr.
For now, we are modeling it as container of raw pointer (no ownership concept).
This time unique_ptr is not derived from std__unique_ptr (unlike shared_ptr, it was easier to not do that) and so we need to provide implementations for all non-member functions per C++ reference:

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". Infer was therefore missing to detect resource leaks when the resource was indirectly implementing Closeable via an intermediate interface.

Summary:This pull request adds the SuppressViewNullability annotation.
The reasoning behind this is that in libraries, one cannot use Butterknife for view binding, which forces you to do it manually. Basically, this makes a new annotation that infer treats the same way as Bind/InjectView

Instead of using the collection of suppress warnings annotations to filter out the errors while generating the error reports, we just add this SuppressWarnings at translation time, like any other annotations, and the reporting functions in the Reporting module will just skip the errors when the method is annotated with SuppressWarnings.
This allows us to have a suppress warnings mechanism that is independant from the integration with the build system.

Summary:public This also required a refactoring of InitListExpr.
The idea is that ImplicitValueInitExpr can stand for initialising a whole struct,
so we translating as a list of zero expressions, according to the struct's fields,
which is then paired with a list of field expressions, such that one get a list of
assignment instructions.

Summary:public
Lazy dynamic dispatch handling works as follows:
Assuming a call of the form:
foo(a);
where the static type of `a` is `A`. If during the symbolic execution, the dynamic type of the variable `a` is `B` where `B <: A`, then we create on-demand a copy `foo(B)` of `foo(A)` where all the uses of the typed parameter `a` are replaced with a parameter of type `B`. Especially, if `foo` contains virtual call, say `get` where `a` is the receiver, then the call gets redirected to the overridden method in `B`, which simulates the runtime behavior of Java.
This lazy dynamic dispatch mode is only turn on for the tracing mode for now in order to avoid conflicts with sblackshear's approach for sound dynamic dispatch.
