libglusterfsclient: Conform'ify glusterfs_readdir

This commit does two things:
1. Changes glusterfs_readdir prototype to conform to the POSIX
readdir().
2. Uses a 1024-byte value instead of sizeof(struct dirent) for the
@size for libgf_client_readdir. This allows even larger names to fit
into a single readdir request to the server.
