[Toybox] bootchart2 and bootchart

[scsijon]

	bootchart2 was created from the fusion of three separate
pieces of work. First - the original bootchart: a shell script, and a
Java visualisation tool written by Ziga Mahkovec. Some of the original
shell scripting, and the concept remain unchanged from this time.

	bootchart2 replaces the Java visualisation with the more
friendly and flexible pybootchartgui (cf. README.pybootchart) written
by Anders Norgaard and Henning Niss, this lives mostly in the
pybootchart/ sub-directory.

	bootchart2 embeds a new collector, based on a port to C of the
inner-loop of the original bootchart collector shell-script by Scott
James Remnant. This has been subsequently re-written by Michael Meeks
to use the higher granularity 'taskstat' data available via a twisted
netlink interface, amongst other new features.

https://github.com/xrmx/bootchart/tree/cross-process-merge seems to be the oldest in the tree now available with v1 code as Ziga's page seems like it has dissapeared.
