Shutdown requests are normally hardware dependent.
By extending pvpanic to also handle shutdown requests, guests can
submit such requests with an easily implementable and cross-platform
mechanism.

This patch was split out from my earlier pvpanic-shutdown series [0].
The original series dropped the usage of the linux/pvpanic.h UAPI
header.
As we decided to keep the linux header [1] this first commit only adds
the spec definition.
Then a patch to Linux will add the new events to linux/pvpanic.h.
After this the rest of the changes to QEMU will be submitted again.
