There are some records which should only be sent once in the stream, and not
repeated for each checkpoint. {start,end}_of_stream() become per-checkpoint,
and a new start_of_stream() is introduced.
There is no resulting change record order, but the X86_PV_INFO record is
identified as once per stream. Currently the X86_PV_P2M_FRAMES record is as
well, but this is because of an implementation bug and can move back to being
on an as-needed basis when fixed.
In addition, a few minor adjustments of comments and layout.

Subject to my finding a suitable documentation update further down the
series:

What update are you expecting? X86_PV_INFO is already strictly defined
as "sent once" in the spec.
Something defining a checkpointed stread.
I think this is done in the 3rd patch? Can I take this ack?
