DEPTH is the depth starting at DIR, even though RECEIVER is never
invoked on DIR: if DEPTH is svn_depth_immediates, then invoke
RECEIVER on all children of DIR, but none of their children; if

not on subdirectories; if svn_depth_infinity, recurse fully.
DIR is a relpath, relative to the root of RA_SESSION.
