Richard Purdie 295f1608b0 scripts/pybootchart: Fix missing entries bug
If two entries have the same start time, the data store used will cause
all but one of the entries to be lost. This patch enhances the data
storage structure to avoid this problem and allow more than one
event to start at the same time.

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

pybootchartgui is a tool 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.
