For now, for vfio pci passthough devices when qemu receives an error from host aer report, there just terminate the guest, but usually user want to know what error occurred but stop the guest, so this patches add aer capability support for vfio device, and pass the error to guest, and have guest driver to recover from the error.
for turning on SERR# patch in seabios list, pls see: http://www.seabios.org/pipermail/seabios/2015-January/008591.html v2-v3: 1. refactor vfio device to parse extended capability. 2. add global property for piix4 to disable vfio aer cap. v1-v2: 1. turn on SERR# for bridge control register in firmware. 2. initilize aer capability for vfio device. 3. fix some trivial bug.
