Make the objfile destructor private

Browse Source 
The idea behind this is that, in the long run, some code will need to
be able to hold onto an objfile after it is unlinked from the program
space.  In particular, this is needed for some functionality to be
moved to worker threads -- otherwise the objfile can be deleted while
still in use.

So, this makes ~objfile private, replacing it with an "unlink" method,
making it more obvious which operation is intended at the calling
points.
