Fix outdated doc for chunk_write.
Removed the no-more-existing "data" and "size" parameters' description,and changed "chunk_id" to "c" as the second parameter.
Add a "get_fds()" method to the chunkiser (useful for RTP input)
Implement the dechunkiser "close" method
Change the dechunkiser API to accept a file name (and not only a config string) in open()
Use a better interface for chunk_write(), too
Use a new interface for chunkise()
First draft of a chunkiser infrastructure
