Change the license of the source code from BSD + PATENTS to MIT.
Change `checkCopyright` to reflect the new license and learn some new file
types.

Summary:
Our model of unique_ptr and shared_ptr relied on the fact that we could C-style cast a pointer to the internal pointer type used in the smart pointer.
This is wrong when the smart pointer is used with a custom deleter that declares its own pointer type whose is not constructible from just a single pointer.

Summary:
Some classes may have deleted new operator for them. To fix it, run global `new` operator instead
```
struct X {
void* operator new(size_t) = delete;
};
X *p = new X; // compilation error
X *p = ::new X; // no compilation error
```
This change is following same strategy standard headers follow.

Summary:
Fixes issue with template argument deduction with enable_shared_from_this as argument
```
#include<memory>
template<class T>
void makeWeak(const std::shared_ptr<T>& x) {}
struct X : public std::enable_shared_from_this<X>{
};
void test() {
X x
makeWeak(x.shared_from_this()); // compilation failed here - it was unable to deduce template parameter of makeWeak
}
```

Summary: Our C++ model magic didn't work when instantiating smart pointers with volatile types. Fix it

Summary:
1. models no longer need access to private fields (shared_ptr needed that)
2. create macro for __attribute__((deprecated("__infer_replace_with_deref_first_arg"))) and use it in models

Summary:
1. Add capability to clang frontend to replace some function calls with another SIL code based on `__deprecated__` attribute.
2. Given this capability, use those attributes for shared_ptr getters to generate `Sil.Load` instruction instead of method call
3. Add test that mimics shared_ptr model, but it doesn't have that much scary C++ templated code

Summary:
Make std::shared_ptr<T> translated as T* inside infer. This will make reporting better
since smart pointers are really pointers not structs - this form is much easier for the analyzer to understand.
This requires changes to the model of shared_ptr as well.

Summary:
So far infer had very fragile mechanism to detect smart pointers. It was looking for "std" and "(shared|unique)_ptr" inside name string.
This is easy to trick (like mystd::shared_ptr) and not something we want.
Instead, inside models create models inside infer_std_model namespace. Then just "export" that model into std namespace
via `using shared_ptr = infer_std_model<T>;`

Summary:
Reuse data fields of model's superclass (which is actual implementation).
Not very pretty, but makes sizeof shared_ptr same as in actual libraries

Summary:public
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.
