A vCPU thread always reaches 100% utilization when:
- guest uses idle=poll
- disable HLT vm-exit
- enable MWAIT
Add new guest agent command 'guest-get-cpustats' to get guest CPU
statistics, we can know the guest workload and how busy the CPU is.

we usually don't care the actions on these devices. But there is a

On Solaris, instead of the -P, -H, and -r flags, we need to provide
the target init state to the 'shutdown' command: state 5 is poweroff,
0 is halt, and 6 is reboot. We also need to pass -g0 to avoid the
default 60-second delay, and -y to avoid a confirmation prompt.

The code for guest-network-get-interfaces needs a couple of small
adjustments for Solaris:

not ifr_hwaddr (ifr_hwaddr doesn't exist on Solaris).
- The implementation of guest_get_network_stats is Linux-specific, so

Since its introduction in commit 3424fc9f16 ("qemu-ga: add
guest-network-get-interfaces command"), guest-network-get-interfaces
seems to check if a given interface has a hardware address by checking
'ifa->ifa_flags & SIOCGIFHWADDR'. But ifa_flags is a field for IFF_*
flags (IFF_UP, IFF_LOOPBACK, etc), and comparing it to an ioctl like
SIOCGIFHWADDR doesn't make sense.
On Linux, this isn't a big deal, since SIOCGIFHWADDR has so many bits
set (0x8927), 'ifa->ifa_flags & SIOCGIFHWADDR' will usually have a
nonzero result for any 'normal'-looking interfaces: anything with
IFF_UP (0x1) or IFF_BROADCAST (0x2) set, as well as several
less-common flags. This means we'll try to get the hardware address
for most/all interfaces, even those that don't really have one (like
the loopback device). For those interfaces, Linux just returns a
hardware address of all zeroes.
On Solaris, however, trying to get the hardware address for a loopback
device returns an EADDRNOTAVAIL error. This causes us to return an
error and the entire guest-network-get-interfaces call fails.
Change this logic to always try to get the hardware address for each
interface, and don't return an error if we fail to get it. Instead,
just don't include the 'hardware-address' field in the result if we
can't get the hardware address.

Currently, commands-posix.c assumes that getifaddrs() is only
available on Linux, and so the related guest agent command
guest-network-get-interfaces is only implemented for #ifdef __linux__.
This function does exist on other platforms, though, such as Solaris.
So, add a meson check for getifaddrs(), and move the code for
guest-network-get-interfaces to be built whenever getifaddrs() is
available.
The implementation for guest-network-get-interfaces still has some
Linux-specific code, which is not fixed in this commit. This commit
moves the relevant big chunks of code around without changing them, so
a future commit can change the code in place.
