Prompted by the recent mails on ksummit, let's actually try to make this
work this time.  We need a container for manipulating strings easily,
and seq_buf is the closest thing we have to it.  The only problem I have
with it is the readpos that is only useful for the tracing code today.
So move it from the seq_buf to the tracing code.

We should go further with this patch series, including using seq_buf
within vsprintf, but if we can't get over this hurdle first, I'm not
going to waste my time on this again.

v2:
 - Add linux-trace-kernel@vger.kernel.org
 - Fix kernel-doc
