Windows reports BSOD parameters through Hyper-V crash MSRs. This
information is very useful for initial crash analysis and thus
it would be nice to see it in the QEMU log file. There is suitable
log mask for the purpose.

Linux guest does not provide this information, but still it would
be nice to log that we have crashed.

Changes from v2:
- fixed PPC compilation

Changes since v1:
- patches resplit
- created property to query crash parameters
- crash parameters added to panic event
