Martin Hundebøll c0dafd3101 scripts: use '/usr/bin/env' in shebangs with python
To support yocto on systems with python3 as default version, scripts
should use /usr/bin/env python in the shebang, as this allows the use of
a fake env to mimic python2 as default version.

This patch simply replaces occurrences of #!/usr/bin/python with
 #!/usr/bin/env python and was done with this oneliner:

     git grep -lE '^#!/usr/bin/python' | xargs \
         sed -i 's|/usr/bin/python|/usr/bin/env python|'

			    PYBOOTCHARTGUI
			   ----------------

pybootchartgui is a tool (now included as part of bootchart2) for
visualization and analysis of the GNU/Linux boot process. It renders
the output of the boot-logger tool bootchart (see
http://www.bootchart.org/) to either the screen or files of various
formats. Bootchart collects information about the processes, their
dependencies, and resource consumption during boot of a GNU/Linux
system. The pybootchartgui tools visualizes the process tree and
overall resource utilization.

pybootchartgui is a port of the visualization part of bootchart from
Java to Python and Cairo.

Adapted from the bootchart-documentation:

  The CPU and disk statistics are used to render stacked area and line
  charts. The process information is used to create a Gantt chart
  showing process dependency, states and CPU usage.

  A typical boot sequence consists of several hundred processes. Since
  it is difficult to visualize such amount of data in a comprehensible
  way, tree pruning is utilized. Idle background processes and
  short-lived processes are removed. Similar processes running in
  parallel are also merged together.

  Finally, the performance and dependency charts are rendered as a
  single image to either the screen or in PNG, PDF or SVG format.
