In the general case, the fine-grained information in a third-party error
might be more complicated than a single integer. So if we want an
svn_error_t to contain this information (and I'm not sure we do),
src_err isn't a very good way of doing it.

I don't quite understand this proposal. If you mean that there would be
an APR error code which says "child->apr_err is a third-party package's
error code," then I find that hackish.

I also don't understand the case for error-handling callbacks. If an
error requires special processing by an inner module, why not perform
that processing before passing back the error in the first place?
