This updates the pybootchart code (used for viewing build timing profiles)
to use python3. The bulk of the changes are to use gi instead of pygtk, i.e.
port from gtk+2 to gtk+3.
The main change is to make the bootchart widget inherit gtk.Scrollable
and change the way the scrollbars are implemented to match the new method
upstream. The drawing code used cairo already so can remain unchanged,

While "Show more" is enabled, all processes are shown, regardless of
--mintime.
This also has the added benefit of making the first shown bar start at
its correct offset from the start time, rather than always starting at
0.

This update the pybootchartgui code to the latest release from its new
location at "https://github.com/mmeeks/bootchart". This only imports
the relevant parts, and not all of bootchart2.

The original patch is from Richard, I rebased it to the up-to-date
upstream code, here are the original messages from him:
We have just merged Beth's initial buildstats logging work. I was
sitting wondering how to actually evaluate the numbers as I wanted to
know "where are we spending the time?".
It occurred to me that I wanted a graph very similar to that generated
by bootchart. I looked around and found pyboootchartgui and then hacked
it around a bit and coerced it to start producing charts like:
http://tim.rpsys.net/bootchart.png
which is the initial "pseudo-native" part of the build. This was simple
enough to test with.
I then tried graphing a poky-image-sato. To get a graph I could actually
read, I stripped out any task taking less than 8 seconds and scaled the
x axis from 25 units per second to one unit per second. The result was:
http://tim.rpsys.net/bootchart2.png
(warning this is a 2.7MB png)
I also added in a little bit of colour coding for the second chart.
Interestingly it looks like there is more yellow than green meaning
configure is a bigger drain on the build time not that its
unexpected :/.
I quite enjoyed playing with this and on a serious note, the gradient of
the task graph makes me a little suspicious of whether the overhead of
launching tasks in bitbake itself is having some effect on build time.
Certainly on the first graph there are some interesting latencies
showing up.
Anyhow, I think this is the first time bitbake's task execution has been
visualised and there are some interesting things we can learn from it.
I'm hoping this is a start of a much more detailed understanding of the
build process with respect to performance.

This is from:
http://pybootchartgui.googlecode.com/files/pybootchartgui-r124.tar.gz
Will modify it to make the build profiling in pictures.
Remove the examples since they would not work any more, and they cost
much disk space.
