Implemented shared memory as an NPObject. Using NPObject method to expose mapping function rather than NPAPI change.
Note that shared memory objects currently lose identity when they cross a process boundary. If an object is sent across a boundary and back, there are now two objects representing the same handle in a single process. This can be fixed.
