[mythtv] ringbuffer.cpp

[Jean-Yves Avenard]

For those running ubuntu 12.04.

I created packages using the devel/027candidates branch

It's pretty much fixes/0.27 but will all the latest changes related to
the ringbuffer and liveTV from master.

Instructions on how to set it up:
http://www.avenard.org/files/ubuntu-repos/

it's the release directory.

The more testing the better...

An important point is that to enjoy all the improved performance, you
*must* run also an updated backend.

a devel/027candidates frontend will work with a stock 0.27 backend, I
made sure everything was backward compatible but it has slight
performance impact.
