Summary: Better documentation, and could perhaps be checked instead of trusted later if the analysis understands threads better.

Summary:
This diff adds a set of access paths holding a value returned from a method annotated with Functional to the domain.
If a "functional" value is written to a field, we won't count that right as an unprotected access.
The idea is to be able to use the Functional annotation to get rid of benign race false positive, such as:
```
Functional T iAlwaysReturnTheSameThing();
T mCache;
T memoizedGetter() {
if (mCache == null) {
mCache = iAlwaysReturnTheSameThing();
}
return mCache;
}
```
Although there is a write-write race on `mCache`, we don't care because it will be assigned to the same value regardless of which writer wins.

Summary:
Some of the new thread-safety annotations are somewhat difficult to understand based on the name alone.
Devs can link a sources JAR with the annotations in their IDE to quickly understand the purpose of each annotation.

Summary:
Similar to marking classes ThreadConfined, we want to support marking fields as well.
The intended semantics are: don't warn on writes to the marked field outside of syncrhonization, but continue to warn on accesses to subfields.

Summary:
Our patch to Javalib has been accepted, so we can parse programs with invokedynamic!
invokedynamic still crashes Sawja, but I have worked around this by replacing all invokedynamic's with invokestatic's before passing them to Sawja.
This means we can handle everything about invokedynamic except calling the correct function (I call a dummy function with the correct signature for now).
We can try to actually call the right method in the future.

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

Simplifies the code to collect the `SuppressWarnings` annotations and makes the code more robust in the sense that not finding the output of the annotation processor will result in an error directly at the top-level instead of later on when trying to load the output file in the Java frontend.

Add to the code to detect violation of the `NoAllocation` annotation. This diff adds the code to detect such issue based on the code of the `PerformanceCritical` checker. In the next diff, I will refine the list of acceptable allocations, like new exceptions, etc, and add the list of corresponding tests.

Summary: public
This is an initial version of the Expensive checker which only report violations on direct calls. The main objective is to setup all the files for this new checker.
The next steps are:
1) run the checker in interprocedural mode
2) Save in the summary of a method foo() the annotation attribute Expensive if a direct callee of foo is annotated with Expensive
3) Check that Expensive is enforced by subtyping, i.e. check that non-expensive method cannot be overwritten by a method annotated with Expensive

Summary:
Added two annotations @TrueOnNull and @FalseOnNull to be used for boolean functions to specify what value is returned when the argument is null.
Added model for TextUtils.isEmpty, which corresponds to the annotation
@TrueOnNull
static boolean isEmpty(@Nullable java.lang.CharSequence s)
Summary:
Passing the list of SuppressWarnings annotations detected during the compilation to InferPrint. The next step will be to add support for error filtering in .inferconfig and use the same mechanism. The annotation processor will generate an .inferconfig like config file and use it to suppress the reports.
Summary:
Setting up a basic annotation processor. Right now, the processor
just saves a map of class -> methods that should be suppressed. Next, this map
needs to be turned into a .inferconfig file.
