07e7102b8e qga: Fix suspend on Linux guests without systemd
Allow the Linux guest agent to attempt each of the suspend methods
(systemctl, pm-* and writing to /sys) in turn.

Prior to this guests without systemd failed to suspend due to
`guest_suspend` returning early regardless of the return value of
`systemd_supports_mode`.

5bfbcc3faa qga/win32: Remove change action from MSI installer
Remove the 'change' button from "Programs and Features" because it does
not checks if a user is an admin or not. The installer has no components
to choose from and always installs everything. So the 'change' button is
not obviously needed but can create a security issue.

099e8cd9ea qga: Drop dangling reference to QERR_QGA_LOGGING_DISABLED
slog()'s function comment advises to use QERR_QGA_LOGGING_DISABLED.
This macro never existed.  The reference got added in commit
e3d4d25206 "guest agent: add guest agent RPCs/commands" along with
QERR_QGA_LOGGING_FAILED, so maybe that one was meant.  However,
QERR_QGA_LOGGING_FAILED was never actually used, and was removed in
commit d73f0beadb "qerror.h: Remove unused error classes".

Drop the dangling reference.

8a29c20597 meson: require 0.61.3
This removes the dependency of dbus-display on --enable-modules.  It also allows
cleanups in modinfo collection and allows moving C++ compiler detection to
meson.build.

Because it is now deprecated to use install_subdir to create an empty directory,
replace it with install_emptydir.

Updating the Meson submodule to 0.61.5 also removes the message

    WARNING: Broken python installation detected. Python files installed
    by Meson might not be found by python interpreter.

unless using system meson is forced with --meson.

Let's use a more appropriate wording for this command line and config
file option. The old ones are still accepted for compatibility reasons,
but marked as deprecated now so that it could be removed in a future
version of QEMU.

This change is based on earlier patches from Philippe Mathieu-Daudé,
with the idea for the new option name suggested by BALATON Zoltan.

And while we're at it, replace the "?" in the help text with "help"
since that does not have the problem of conflicting with the wildcard
character of the shells.

bbb0151cf2 qga: treat get-guest-fsinfo as "best effort"
In some container environments, there may be references to block devices
witnessable from a container through /proc/self/mountinfo that reference
devices we simply don't have access to in the container, and cannot
provide information about.

Instead of failing the entire fsinfo command, return stub information
for these failed lookups.

This allows test-qga to pass under docker tests, which are in turn used
by the CentOS VM tests.

22668881f3 qga: Introduce disk smart
After assigning a NVMe/SCSI controller to guest by VFIO, we lose
everything on the host side. A guest uses these devices exclusively,
we usually don't care the actions on these devices. But there is a
low probability that hitting physical hardware warning, we need a
chance to get the basic smart log info.

Introduce disk smart, and implement NVMe smart on linux.

Thanks to Keith and Marc-André.

c8ec041d00 qga/commands-posix: 'guest-shutdown' for Solaris
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.

Implement this logic under an #ifdef CONFIG_SOLARIS, so the
'guest-shutdown' command works properly on Solaris.

70335c4644 qga/commands-posix: Fix listing ifaces for Solaris
The code for guest-network-get-interfaces needs a couple of small
adjustments for Solaris:

- The results from SIOCGIFHWADDR are documented as being in ifr_addr,
  not ifr_hwaddr (ifr_hwaddr doesn't exist on Solaris).

- The implementation of guest_get_network_stats is Linux-specific, so
  hide it under #ifdef CONFIG_LINUX. On non-Linux, we just won't
  provide network interface stats.

aec0730ea9 qga/commands-posix: Fix iface hw address detection
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.

59e35c7b65 qga/commands-posix: Use getifaddrs when available
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.

ff5927baa7 util: rename qemu_*block() socket functions
The qemu_*block() functions are meant to be be used with sockets (the
win32 implementation expects SOCKET)

Over time, those functions where used with Win32 SOCKET or
file-descriptors interchangeably. But for portability, they must only be
used with socket-like file-descriptors. FDs can use
g_unix_set_fd_nonblocking() instead.

Rename the functions with "socket" in the name to prevent bad usages.

This is effectively reverting commit f9e8cacc55 ("oslib-posix:
rename socket_set_nonblock() to qemu_set_nonblock()").
