Let's do a mental experiment. Think about what it would be like if you
chose to pass several of the values that had already been read from the
database. That would start to get messy if they were all separate
params, so we would build a structure that held the values, and pass a
pointer to it. We could generalize the structure to hold all possible
__db_read_info() data, with each value optionally present or not (marked
by an invalid value). It would effectively be a cache. It could also
hold a pointer to the DB it came from, so we wouldn't need to pass that
separately, and we could call the pointer to the struct "a handle to the
DB". See where I'm going?
It seems to me that we should rely on svn_wc__db_read_info() to be
efficient. If it needs caching to be fast, it should implement the
equivalent of that hypothetical struct internally.
