[LTP] [PATCH 0/4][RT][RFC][Take#5] XML dumps for realtime tests

[Gilles C. <gil...@bu...>]

Hello,

To overcome libstats limitations, I have implemented this library and
integrated it into libstats matrix_mult.c

I've used this because I had to compare/correlate stats of differents tests
runs on several kernels and architectures. This proved very useful as once the
tests have run, many extracts can be done from original results, without
having to modify/recompile/rerun the test itself.
This really made things easier.

With a single test run output, I could plot 2-D or 3-D graphs just by changing
the xquery that generates the gnuplot data file.

Basic understanding of XML is necessary to use this.

I think this work is worth sharing. I wish people review it and comment it.

Though it's been implemented on top of realtime tests, it should be easily
portable to the reset of LTP, should some be interested...

This series consists of four patches:
	first is the library itself,
	second is the integration with libstat,
	third is a first use with matrix_mult,
	forth is the documentation and a tool.
