add chunk_alloc to playlist.c #2
dc_thread_playlist was asking for invalid indices since previously the name buffer would have been valid it just got whatever junk data was left over add dc_discard_playlist_pointers for HAVE_DIRCACHE targets this allows the dc_playlist_thread to stop its current lookup loop Change-Id: I6f25b97b8c4e314d27c5e1e6ff0925b5a3e93f26
