[Qemu-devel] [PATCH 0/5 v2] convert system_powerdown command to notifiers

[Igor Mammedov <imammedo@redhat.com>]

global variable qemu_system_powerdown in sysemu.h is the only dep for qemu_irq
and qemu_rise_irq is not a generic way to signal guest that it should shutdown.

So replace it by notifiers and allow each implementation to have it's own way
to notify guest.

git repo for testing:

compile tested:
   target-list=x86_64-linux-user,x86_64-softmmu,sparc-softmmu,arm-softmmu
runtime tested:
   x86_64-softmmu + win7 guest

ps:
 reposting because I forgot to add qemu-devel address.
