Detailed Description

Implementation of some atomic operations (elementary operations with data that cannot be interrupted by parallel threads in the multithread process) on various platforms.

By the moment, only operations necessary for reference counter in Standard_Transient objects are implemented.

This is preffered to use fixed size types "int32_t" / "int64_t" for correct function declarations however we leave "int" assuming it is 32bits for now.
