class CopyablePtr

This class is essentially a std::vector

> of fixed size = 1.

It's a pointer wrapper with deep copying and deep equality comparison.

At all effects this wrapper behaves like the underlying T, with the exception

of the heap indirection.

Conversely to a std::unique_ptr, the pointer will be always valid, never

null. The problem it solves is the following: when generating C++ classes

from proto files, we want to keep each header hermetic (i.e. not #include

headers of dependent types). As such we can't directly instantiate T

field members but we can instead rely on pointers, so only the .cc file needs

to see the actual definition of T. If the generated classes were move-only we

could just use a unique_ptr there. But they aren't, hence this wrapper.

Converesely to unique_ptr, this wrapper:

- Default constructs the T instance in its constructor.

- Implements deep comparison in operator== instead of pointer comparison.
