/**
* Iterate over all entries in a directory. Note that directories
* are structured such that it is possible to iterate over the
* individual blocks as well as over the entire directory. Thus
* a client can call this function on the buffer in the
* GNUNET_FS_ProgressCallback. Also, directories can optionally
* include the contents of (small) files embedded in the directory
* itself; for those files, the processor may be given the
* contents of the file directly by this function.
* <p>
*
* Note that this function maybe called on parts of directories. Thus
* parser errors should not be reported _at all_ (with GNUNET_break).
* Still, if some entries can be recovered despite these parsing
* errors, the function should try to do this.
*
* @param size number of bytes in data
* @param data pointer to the beginning of the directory
* @param offset offset of data in the directory
* @param dep function to call on each entry
* @param dep_cls closure for dep
* @return GNUNET_OK if this could be a block in a directory,
* GNUNET_NO if this could be part of a directory (but not 100% OK)
* GNUNET_SYSERR if 'data' does not represent a directory
