PATCH 1/3 bootimg.bbclass: fix settings for grub-efi.bbclass

Fixed:
- Found potential conflicted var LABELS ...
Set LABELS to "boot install" would build out broken images when build vm + live together, use set_live_vm_vars() to fix the problem.

- Use ROOT and LABEL in boot-directdisk.bbclass and image-foo.bbclass, they are not only used by syslinux.bbclass, but also grub-efi.bbclass, add "SYSLINUX_" prefix would mislead users.

PATCH 2/3 grub-efi.bbclass: make it can build vm and live together

In reply to Robert Yang

* Make it can build vm and live (e.g., iso + vmdk) together as we did for syslinux.
* GRUBCFG -> GRUB_CFG as other GRUB_FOO vars

syslinux.bbclass should not be seen when use efi.

That's not completely true, there is a case which still requires the ioslinux.bin binary when EFI is used. In the build_iso() function there is a workaround that is still required and uses isolinux.bin

This change breaks building EFI only machines (intel-quark for example)

Please check into this.
Thanks

Sau!

I had built EFI only boards before send this, it worked well. I will check meta-intel's intel-quark .
