Description

Update rbd_types.h to match the userspace version, and add support for opening new-format images while keeping support for old-style images in place.
This involves detecting the format of the image and using the new rbd class methods for interacting with the new-style header.

Status changed from New to In Progress

I've finally begun work on this, following some in-person discussion
with Josh, Dan, and Sage this week.

I will update when I have a bit more detail to report, but right now
I'm working on producing the functions to call the get_immutable_metadata()
and get_mutable_metadata() rbd object methods and see what the result looks
like.
