[PATCH] Convert svn_fs_base__get_node_successors() to dual-pool paradigm

[Daniel Shahaf]

I wrote this while debugging some pool segfaults, and I don't want to
commit it until I've resolved them (for obvious reasons), so I'm abusing
all of your inboxes as my personal patch queueing system.  Thanks for
your cooperation.
