Daniel Henrique Barboza fb06411210 qmp hmp: Make system_wakeup check wake-up support and run state 
The qmp/hmp command 'system_wakeup' is simply a direct call to
'qemu_system_wakeup_request' from vl.c. This function verifies if
runstate is SUSPENDED and if the wake up reason is valid before
proceeding. However, no error or warning is thrown if any of those
pre-requirements isn't met. There is no way for the caller to
differentiate between a successful wakeup or an error state caused
when trying to wake up a guest that wasn't suspended.

This means that system_wakeup is silently failing, which can be
considered a bug. Adding error handling isn't an API break in this
case - applications that didn't check the result will remain broken,
the ones that check it will have a chance to deal with it.

Adding to that, the commit before previous created a new QMP API called
query-current-machine, with a new flag called wakeup-suspend-support,
that indicates if the guest has the capability of waking up from suspended
state. Although such guest will never reach SUSPENDED state and erroring
it out in this scenario would suffice, it is more informative for the user
to differentiate between a failure because the guest isn't suspended versus
a failure because the guest does not have support for wake up at all.

All this considered, this patch changes qmp_system_wakeup to check if
the guest is capable of waking up from suspend, and if it is suspended.
After this patch, this is the output of system_wakeup in a guest that
does not have wake-up from suspend support (ppc64):

(qemu) system_wakeup
wake-up from suspend is not supported by this guest
(qemu)

And this is the output of system_wakeup in a x86 guest that has the
support but isn't suspended:

(qemu) system_wakeup
Unable to wake up: guest is not in suspended state
(qemu)

/*
* Notably absent: Proper permission management. This is sad, but it seems

* limiting the use cases of the qemu-io HMP command.
*
* In an ideal world we would unconditionally create a new BlockBackend for
* qemuio_command(), but we have commands like 'reopen' and want them to
* take effect on the exact BlockBackend whose name the user passed instead
* of just on a temporary copy of it.
*
* Another problem is that deleting the temporary BlockBackend involves
* draining all requests on it first, but some qemu-iotests cases want to
* issue multiple aio_read/write requests and expect them to complete in
* the background while the monitor has already returned.
*
* This is also what prevents us from saving the original permissions and
* restoring them later: We can't revoke permissions until all requests
* have completed, and we don't know when that is nor can we really let
* anything else run before we have revoken them to avoid race conditions.
*
* What happens now is that command() in qemu-io-cmds.c can extend the
* permissions if necessary for the qemu-io command. And they simply stay
* extended, possibly resulting in a read-only guest device keeping write
* permissions. Ugly, but it appears to be the lesser evil.
