After upgrade `qapitrace` have working "Buffers" tab where the data
can be inspected (it was always empty before).
There is no tags after `7.1`, but I think that fixing pretty important
piece of functionality warrants an upgrade to current `master` tip.
This will probably be mandatory soon, and is a step in the right
direction. Removes the deprecated meta.version, and move some meta
sections to the end of the file where I should have put them in
the first place.
