The libxl thing is already committed (2ff2adc61fcfa0).

Plan 1 (committing dumps into the tree) won't work. Plan 2 (OSSTest and
other systems doing a double checkout) probably does require a tweak or
two in 4.15 to make it easy to start in 4.16.
Also, "xenstore_lib.h and libxenstore API/ABI problems" still has work
to do for 4.15.

Still one known issue remaining, as pointed out in Roger's summary. I'm
still working on it.
