OE RPB and Zeus release

hi there,

I've pushed all needed changes to get started with Zeus builds for the Linaro OE RPB CI:

* created zeus branch on meta-backports, meta-qcom * created zeus branch on oe-rpb-manifest * i did not create zeus and i am keeping master for meta-rpb, meta-96boards, meta-linaro. it's compatible, at least for now * our zeus manifest is using master for other layers when they don't have a zeus branch

Build #1 is scheduled for now.. we will see how bad it goes.

I have also create the qcom/zeus branch (I recall that it is a stripped down version of the overall Linaro manifest that only focuses on Qualcomm BSP).

Of course, if you can keep an eye on builds and help fixing issues, that would be much appreciated.

cheers nico
