Willy Tarreau cdc9ddc8cf MINOR: flags/channel: use flag dumping for channel flags and analysers 
The two new functions are chn_show_analysers() and chn_show_flags().
They work on an existing buffer so one was declared in flags.c for this
purpose. File flags.c does not have to know about channel flags anymore.
