Update the existing stress tests to ensure that we can handle
reflinking the same block a million times, and that we can handle
reflinking million different extents. Add a couple of tests to ensure
that we can ^C and SIGKILL our way out of long-running reflinks.
v2: Don't run the signal tests on NFS, as we cannot interrupt NFS
clone operations.

Add a few horrible opt-in stress tests to see what happens if we try
to reflink the same block billions of times, and what happens if we
run out of space while reflinking a file.
