Summary: move + remove stored as cycle

Initial Comment:
Some versions of aegis (4.20, 4.21, perhaps others) saved metadata for files which were renamed (a->b) and removed (aerm b) within the same branch incorrectly.  The metadata represents a rename cycle (a->b and b->a).  I presume this is because there is only a "move" field in the structures, not "moved-to" and "moved-from".  I have not checked whether recent versions still do this, but even if they do not, such metadata lives in our repositories.   

A process which looks through the metadata (like aegis -list change_files) can go into an infinite loop when encountering this.  It looks like the weakness is in libaegis/project/file/find_by_meta.cc, maybe elsewhere as well.  The curious thing is that "aegis -list" in aegis-4.23.D205 finds the infinite loop, but aegis-4.22.1 does not. (Example for developers: aegis -list -unf -p aegis.4 -c 20 cf)
