Sync primitive for multiple reads and exclusive locking change access

Desc: Useful in case if you have rarely modified object that needs to be read quite often from different threads but still need to be exclusively modified sometimes Debug functionality: Can be used for debug-only lock calls, which verify that no simultaneous access is attempted. Use the bDebug argument of LockRead or LockModify, or use the DEBUG_READLOCK or DEBUG_MODIFYLOCK macros. There is no overhead in release builds, if you use the macros, and the lock definition is inside #ifdef _DEBUG.
