Gather most of the necessary information for the thread 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 thread_snapshot may end up in a
different file completely, but until we pick a
serialization/deserialization method, keep it as-is.
