Perf python scripting support

Ingo,

Please pull the perf/core branch that can be found at:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing.git
	perf/core

I've left out the parts that deal with syscall nr to name
resolution as it would be nicer to implement it through events
injection instead of yet another debugfs file.

The reason I've made a separate patch to tag syscall_name()
helper as unavailable yet is that it makes it easily
revertable later, once it gets supported.

I've tested the whole and it works very well.

Thanks,
	Frederic
