Upgrade all nested externals recursively. Previously, only the first level of
dir externals was upgraded, not the dir externals *inside* dir externals.
For externals, recurse instead of calling svn_wc_upgrade(), so that
externals defined therein are also looked up. Introduce ITERPOOL2, to
clear after each single externals item, each potentially a huge nested WC.
