    kernel-yocto: allow branch auditing to be suspended
    
    When working on the yocto-bsp and kernel-lab update for yocto 1.2
    we found it was impossible for a end-user BSP to isolate patches
    on a branch, since with the following commit:
    
      [kernel-yocto: enforce SRC_URI specified branch]
    
    Any new branch would be switched to whatever was specified on the
    SRC_URI and undoing the work that the yocto-bsp tool did to support
    board specific patches.
    
    To fix this, we'll keep the enforcing of branch consistency enabled
    by default, but introduce a variable "KMETA_AUDIT" that when not
    set will skip the check.
    
    There's no impact for existing users, and it is only something that
    other plumbing commands and tools will need to use (or care about).
