Gather most of the necessary information for the module snapshot. Note that: - The 'capture' portion of this CL will be moved out of the snapshot interface and into a separate in-process dump to disk location. - All of the pointer dereferences need to be wrapped in vm_read. - The read-fast-and-dump logic in module_snapshot may end up in a different file completely, but until we pick a serialization/deserialization method, keep it in module_snapshot_ios.
