[XEN,for-4.13,v2,0/9] libxl memkb & pt defaulting

Message

This is v2 of my series to sort out the shadow/iommu memory and pci
passthrough situation.  I think this series will mask the bug which is
currently blocking staging propagating to master.

I had some difficulty testing this, as the test box under my desk
doesn't do PT and I didn't want to wait to book one out from the test
lab.  So I have executed only some of the new code in libxl.

I would really appreciate review by a hypervisor expert on the main
chunk of new code in libxl added in patch 9, which is where all the
logic related to passthrough enabling and mode now resides.

 am 1 libxl: Offer API versions 0x040700 and 0x040800
 r  2 xl: Pass libxl_domain_config to freemem(), instead of b_info
 r* 3 libxl: libxl__domain_config_setdefault: New function
 r* 4 libxl: libxl_domain_need_memory: Make it take a domain_config
  * 5 libxl: Move shadow_memkb and iommu_memkb defaulting into libxl
 a  6 libxl: Remove/deprecate libxl_get_required_*_memory from the API
  + 7 libxl: create: setdefault: Make libxl_physinfo info[1]
  + 8 libxl: create: setdefault: Move physinfo into config_setdefault
  + 9 libxl/xl: Overhaul passthrough setting logic
