perf-scripting/perf-tui features, v3

From: Tom Zanussi <[email protected]>

This patchset enables the Perl and Python bindings for perf, as well as the perf TUI (text-based UI).

These are now turned on by default via a new variable, PERF_FEATURES_ENABLE, which can be overridden if the default set of perf features aren't desired (perf-scripting and perf-tui).

Because perf isn't normally enabled except in sdk builds, which contains most of the additional packages that these features drag in anyway e.g. Python and Perl, it shouldn't be too bothersome to unconidtionally turn the perf features on if perf itself is enabled. Future work will probably allow these features to be disabled individually using PACKAGECONFIG for example.

These changes need corresponding changes made to linux-yocto and posted separately on the yocto and linux-yocto mailing lists.

This patchset depends on the associated kernel changes posted along with the original patchset:

http://www.mail-archive.com/[email protected]/msg07286.html

Bruce Ashfield submitted a SRCREV update for the 3.4 kernel today that you'll also need to build this.

I just started testing this, it works so far, but thought I'd put it out there now in case there were comments before putting too much effort into that, and possibly giving other people a chance to try it out.

This patchset has been build-tested on the following machines:

qemuarm
