Ugh. There isn't a single svn_pool_clear() in libsvn_ra_serf/log.c.

That should be fixed. log_context_t should grow an "item_pool" that is
cleared on each call to push_state(ITEM). Then all the log_entry stuff
is placed into that pool, and passed to the receiver. That item_pool
would also be the scratch_pool passed to the receiver.

The log_info_t would lose its pool member. (and it really should be
called something like log_element_t since it always corresponds
directly to an XML element)

Thoughts?
