This is a code simplification patch. - It confines most of the implementation channel implementation into fuse_loop_mt (which is its only user). - It makes it more obvious in the code that channels are only ever used when using -o clone_fd and multi-threaded main loop. - It simplies the definition of both struct fuse_session and struct fuse_chan. - Theoretically it should result in (minuscule) performance improvements when not using -o clone_fd. - Overall, it removes a lot more lines of source code than it adds :-).
