- connections are now matched to format plugins based on content-type headers,
and are rejected if there isn't a format handler for that content-type, or
there is no content-type at all.
- format_vorbis now handles pages with granulepos of -1 in the headers
correctly (this happens if the headers are fairly large, because of
many comments, for example).
- various #include fixes.
- buffer overflow in httpp.c fixed.
