course also be done the other way around, but I think this way the
resulting code can be more efficient).

[LIBELF] Prefer PT_NOTE segments to SHT_NOTE sections for ELF notes.

It's always an error to try to use sections on an executable; the
segments in the phdr are definitive.

Unfortunately we cannot drop SHT_NOTE support completely due to a
binutils bug which causes kernels to have the offset field of the
PT_NOTE phdr set to zero:

http://sourceware.org/bugzilla/show_bug.cgi?id=594

This bug is present in binutils 2.17 although some distros have
backported the fix.

Therefore we simply prefer a PT_NOTE segment if we find one otherwise
we still use the SHT_NOTE section (and then the old __xen_guest
section).

Based on a patch from Jeremy Fitzhardinge.

Also added XEN_ELFNOTE_HV_START_LOW to readnotes.

[TAPDISK] add tapdisk support for image chaining

Enables tapdisk to chain an arbitrary number of VDIs, propagating reads of

tapdisk interface to facilitate this.  Modifies the QCoW plugin to take
advantage of these changes, thus providing support for arbitrarily long chains
of QCoW image types.
