[XEN PATCH 0/X] tools/libxl: XSA-403 follow-up

[Anthony PERARD]

Hi,

Two patches:
    - one for stable branches (I've rework the XSA's patch on 4.16 so
      patch will need to be backported);
    - and one patch for staging, forward porting the patch for stable
      branches.

Those patches are a rework of the patch for the stable branches available
in XSA-403. The environment variable is now in upper case, like one
would expect, and now a value of "0" as the same meaning as the variable
been absent. Also, there's a bit of documentation in `man xl`.

Thanks,
