It can be useful to figure out which NBD protocol features are exposed by a server, as well as what features a client will take advantage of if available, for a given qemu release. It's not always precise to base features on version numbers (thanks to downstream backports), but any documentation is better than making users search through git logs themselves. This patch originally stemmed from a request to document that pristine 3.0 has a known bug where NBD_OPT_LIST_META_CONTEXT with 0 queries forgot to advertise an available "qemu:dirty-bitmap" context, but documenting bugs like this (or the fact that 3.0 also botched NBD_CMD_CACHE) gets to be too much details, especially since buggy releases will be less likely connection targets over time. Instead, I chose to just remind users to check stable release branches.
