No functional change.

The purpose is to make it easier to backport patches from Xen 4.3's
libxl, as Xen 4.3's libxl has had this done:

    libxl: Enable -Wshadow.

    It was convenient to invent $(CFLAGS_LIBXL) to do this.

    Various renamings to avoid shadowing standard functions:
      - index(3)
      - listen(2)
      - link(2)
      - abort(3)
      - abs(3)

In this patch we do not change the others, and we do not enable
-Wshadow.  We're just trying to bring 4.2's libxl textually closer to
4.3's.
