linux-yocto: build changes, 4.1 and libc-headers

Hi all,

This series absolutely needs some more testing and runs through the autobuilder, but I've done pretty much all I can do with it here.

I have more changes to the build process that will follow this, but these changes need to show that they are stable, so here's the first blast.

With this series:

- I create the 4.1, and 4.1-rt linux-yocto content. This will be the new LTSI kernel. Deletion of 3.14 and 3.19 will follow once all machines have been moved forward.

- libc-headers updated to match the 4.1 kernel version.

And the one that could cause some issues/compatibility issues is the split of the kernel configuration data from the kernel tree itself.

From the commit log:

The linux-yocto tree has always been a combined set of kernel changes and configuration (meta) data carried in a single tree. While this format is effective at keeping kernel configuration and source modifications synchronized, it isn't always obvious to developers on how to manipulate the meta data versus the source.

With this change, we remove the meta data processing from the kernel-yocto class and use the external meta-data repository that has always been used to seed the linux-yocto meta branch.

After this change, linux-yocto can no longer process combined trees, and is simplified as a result.

I'm interested to find out if we get any breakages or severe compability issues with the change. I don't want to support both variants of the meta data (in and out of tree), since the goal is to reduce complexity in the code. Once this change lands, I'll further streamline things.

I've built core-image-kernel-dev and boot tested the qemu* machines. qemuppc continues to show a boot failure with systemd, but we have a bugzilla to track that.

I'm now doing graphical testing, but wanted to get this out and soaking for other images types while I wait for builds to churn.

Cheers,

Bruce
