Not just the error handling, also the stat'ing.
Which, I suspect, will hurt performance on filesystems where you get
stat info for free with the list of file names. That includes all
Windows filesystems.
Wouldn't it be better if svn_io_get_dir_filenames returned the same kind
of hash as svn_io_get_dirents2, but only filled in the other info if
it's available? IIRC APR will tell us which fields in the apr_finfo_t
are valid, and will fill more than just the name, even if that's all you
request. Later on, this information could be used to avoid further stats.
