2020-01-14misc: pvpanic: add crash loaded eventzhenwei pi1-0/+1
Some users prefer kdump tools to generate guest kernel dumpfile, at the same time, need a out-of-band kernel panic event. Currently if booting guest kernel with 'crash_kexec_post_notifiers', QEMU will receive PVPANIC_PANICKED event and stop VM. If booting guest kernel without 'crash_kexec_post_notifiers', guest will not call notifier chain. Add PVPANIC_CRASH_LOADED bit for pvpanic event, it means that guest kernel actually hit a kernel panic, but the guest kernel wants to handle by itself.

2020-01-14misc: pvpanic: move bit definition to uapi header filezhenwei pi1-0/+8
Some processes outside of the kernel(Ex, QEMU) should know what the value really is for, so move the bit definition to a uapi file.
