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.

charset="utf-8" Since its introduction in commit 3424fc9f16a1 ("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.

We also need to pass -g0 to avoid the default 60-second delay, and -y to avoid a confirmation prompt. Implement this logic under an #ifdef CONFIG_SOLARIS, so the 'guest-shutdown' command works properly on Solaris.
