Make svnserve recognise when the client does not want inherited
properties.  This fixes a performance problem with 1.8 servers
sending too much data.

* subversion/svnserve/serve.c
  (get_file, get_dir): Properly handle the optional wants_inherited_props
   flag to avoid sending inherited properties when not requested.
