The attached patch gives the user ability to define how many symbolic
links rsync should follow before actually adding it to the file list.

The patch has been heavily modified from its original form to work
with the latest codebase, but even in its original form it didn't
handle relative symlinks properly, and that has not yet been fixed
in this modified version.
