pci, pc, virtio bug fixes

Browse source 
This reverts PCI master abort support - we'll want it
 eventually but it exposes too many core bugs to be safe for 1.7.
 This also reverts a recent exec.c change that was an
 attempt to work-around some of these core bugs.
 
 Also included are small fixes in pc and virtio,
 and a core loader fix for PPC bamboo.
