Replace the current NULL-terminated array of default groups with a linked
list.  This gets rid of lots of nasty code to size and/or dynamically
allocate the array.

While we're at it also provide a conveniant helper to remove the default
groups.

This is a very nice simplification to drop the long-standing fixed size
->default_groups[] usage tree-wide for configfs consumers.

For the target parts:

Also, this applies cleanly to target-pending/for-next, so I don't see a
problem merging it up via your new configfs tree.

Otherwise let me know, and I'll be happy to merge via target-pending.

Thanks HCH.
