reflink: ensure that we can handle reflinking a lot of extents

Browse Source 
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.
