 Log Message:
 lists: Remove bogus libfoo.so.N and libfoo.so.N.M obsolete entries.
 
 These must stay around so applications linked against them will still
 work after upgrade, even if libfoo.so now points to libfoo.so.(N+1)
 or libfoo.so.N.(M+1).
 
 Exceptions:
 
 - I'm willing to believe the rump modules have a different story so I
   left those obsolete entries alone.
 
 - libuv.so was never supposed to be exposed publicly anyway and never
   went out in a release.  (Maybe this information should be recorded
   somewhere?)
 
 - Same is probably true of lib{gmp,mpc,mpfr}.so, not sure of the
   history.  Maybe libg2c.so too, no idea what that is.
 
 - libisns.so was moved from /usr/lib to /lib, so it's legitimate for
   the debug data to live there too now.  (XXX Maybe we should have a
   separate marker for this.)
 
 - Libraries under /usr/tests are not used by normal applications, so
   they can safely be deleted when obsoleted.
 
 Note: The libfoo.so symlink for a library that has been deleted
 altogether, not just upgraded, can be obsoleted.  Loadable modules
 that applications aren't linked against can be obsoleted, even if
 some of them like npf ext_*.so or pam_*.so are formally versioned
 (for reasons unclear to me).
 
 Note: This means that incremental builds may complain about these
 .so.N and .so.N.M files in destdir (PR misc/57581), but it's much
 worse for an upgrade to break working applications.
