demux, stream: remove old rar support in favor of libarchive

The old rar code could do uncompressed rar, libarchive supports at least
some rar compression algorithms. There is no need to keep the old rar
code.

-This works as follows:
-
-- stream_open() with file01.rar
-    - is opened as normal file (stream_file.c or others) first
-    - demux_rar.c detects it
-    - if multi-part, opens file02.rar, file03.rar, etc. as actual streams
-    - it returns a playlist with entries like this to the player:
-        rar://bla01.rar|subfile.mkv
-      (one such entry for each file contained in the rar)
-- stream_open() with the playlist entry, e.g. rar://bla01.rar|subfile.mkv
-    - leads to rar_entry_open()
-    - opens bla01.rar etc. again as actual streams
-    - read accesses go into subfile.mkv contained in the rar file(s)
