Fix fc_atomic_ptr_get and use. Before this change building with ThreadSanitizer and running test/test-pthread generated a large number of threading issues. These mostly stemmed from fc_atomic_ptr_get not doing an atomic load and using "acquire load" instead of "load acquire". After making these changes it was still necessary to use fc_atomic_ptr_get where it was needed. This also documents the current memory barrier requirements for the atomic primitives.
