[PATCH 0/3] add MEMORY_FAILURE event |

Although QEMU could catch signal BUS to handle hardware memory
corrupted event, sadly, QEMU just prints a little log and try to fix
it silently.
In these patches, introduce a 'MEMORY_FAILURE' event with 4 detailed
actions of QEMU, then uplayer could know what situaction QEMU hit and
did. And further step we can do: if a host server hits a 'hypervisor-ignore'
or 'guest-mce', scheduler could migrate VM to another host; if hitting
'hypervisor-stop' or 'guest-triple-fault', scheduler could select other
healthy servers to launch VM.

target-i386: seperate MCIP & MCE_MASK error reason
iqapi/run-state.json: introduce memory failure event
target-i386: post memory failure event to uplayer
