This commit is separate from the previous one to separate our own changes from changes merged from mplayer2 (as far as that was possible). Make it easier for stream implementations to request being cached. Set a default cache size in stream.c, and remove them from various stream implementations. Only MS streaming support sets a meaningful cache size. Make querying cache size saner. This reduces the amount of #ifdefs needed.
