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:

Create initial model of C++ std::shared_ptr. This means that infer will replace implementation of
shared_ptr and the resulting binary will change. Make sure no one will run it by crashing any binary that includes that code.

While playing with the type environment for Java, I realised that the types in models.jar where not re-generated when modifying Infer. As a consequence, some changes in Infer where surprisingly having no effect. This diff forces the type environment to be absent when analyzing the models.

When building models, make was invoked explicitly with `make -j` rather
than with `$(MAKE)`. This prevented controlling parallelism from the

The case when a resource leaks is reported because the the resource was not closed on the execution branch created by the preconditions checks are not very interesting in practice because the exceptions thrown, either `NullPointerException` or `IllegalStateException` are very rarely caught anyway. So the legimate use of preconditions checks is creating spurious resource leak reports.

The classes `java.util.zip.{Inflater/Deflater}` where not modelled as resources. In practice, bad memory leak can happen using these classes and forcing the call to `end()` can help to avoid waisting native memory.

The models for InputStreamReader and OutputStreamWriter are taking into consideration the charset passed as parameter in order to follow the exception branch when the charset is not valid. However, the previsous models were only considering encoding literals with uppercase letters. This diff adds the lowercase encoding names to the list.

Test Plan: Infer CI. No functional change intended.
Summary:

Attaching the resource attribute to the object allows to more easily remove this attribute during the symbolic execution when the resource is passed as a argument, e.g. with `res.close()` or when this resource is passed around via a skipped function.
