Create a base class for reference counting any objects that need to be reference counted

[galdar496]

Store a reference count internally and have functions to increment/decrement the reference count.

Functions:

• AddReference()
• RemoveReference()
• GetReferenceCount()
• DeleteThisObject() \ Make this function virtual so that objects can customize the deletion behavior. For example, placing the objects on a list for later deletion.

Use an atomic and compare_and_exchange in order to perform proper threadsafety for all reference counted objects. Logic:

uint32 oldCount;
uint32 newCount;
do
{
    oldCount = m_count;
    newCount = oldCount - 1;
} while (compare_and_exchange(&m_count, oldCount, newCount);

if (newCount == 0)
{
    DeleteThisObject();
}
