qdev: add return value to init() callbacks.
Sorry folks, but it has to be. One more of these invasive qdev patches.
We have a serious design bug in the qdev interface: device initcallbacks can't signal failure because the init() callback has noreturn value. This patch fixes it....
qdev: convert watchdogs
-watchdog NAME is now equivalent to -device NAME, except it treatsoption argument '?' specially, and supports only one watchdog.
A side effect is that a device created with -watchdog may now receivea different PCI address.
i6300esb is now available on any machine with a PCI bus, not just PCs....

Remove io_index argument from cpu_register_io_memory()
