The null-machine code used to be target specific since it used the
target-specific cpu_init() function in the past. But in the recent
commit 2278b93941d42c30e2950 ("Use cpu_create(type) instead of
cpu_init(cpu_model)") this has been change, so that the code now
uses the common cpu_create() function instead. Thus we can put
the null-machine into the common-obj list so that it is compiled
only once for all targets, to save some compilation time.

The migration test for s390x sometimes hangs when running with TCG,
similar to the problems that we have already observed with TCG for
the ppc64 guests. Thus disable the s390x test when we are not running
with KVM for now until the problem with TCG has been resolved.

In several places we use assert(FEATURE), and assume that if FEATURE
is disabled, all following code is removed as unreachable. Which allows
us to compile-out functions that are only present with FEATURE, and
have a link-time failure if the functions remain used.
MinGW does not mark its internal function _assert() as noreturn, so the
compiler cannot see when code is unreachable, which leads to link errors
for this host that are not present elsewhere.
The current build-time failure concerns 62823083b8a2, but I remember
having seen this same error before. Fix it once and for all for MinGW.

When user provides a long domainname or hostname that doesn't fit in the
DHCP packet, we mustn't overflow the response packet buffer. Instead,
report errors, following the g_warning() in the slirp->vdnssearch
branch.
Also check the strlen against 256 when initializing slirp, which limit
is also from the protocol where one byte represents the string length.
This gives an early error before the warning which is harder to notice
or diagnose.

nettle 2.7.1 was released in 2013 and all the distros that are build
target platforms for QEMU [1] include it:
RHEL-7: 2.7.1
Debian (Stretch): 3.3
Debian (Jessie): 2.7.1
OpenBSD (ports): 3.4
FreeBSD (ports): 3.4
OpenSUSE Leap 15: 3.4
Ubuntu (Xenial): 3.2
macOS (Homebrew): 3.4
Based on this, it is reasonable to require nettle >= 2.7.1 in QEMU
which allows for some conditional version checks in the code to be
removed.

bdrv_img_create() takes an Error ** argument and uses it in the
conventional way, except for one place: when qemu_opts_do_parse()
fails, it first reports its error to stderr or the HMP monitor with
error_report_err(), then error_setg()'s a generic error.
When the caller reports that second error similarly, this produces two
consecutive error messages on stderr or the HMP monitor.
When the caller does something else with it, such as send it via QMP,
the first error still goes to stderr or the HMP monitor. Fortunately,
no such caller exists.
Simply use the first error as is. Update expected output of
qemu-iotest 049 accordingly.

Calling error_report() from within a function that takes an Error **
argument is suspicious. drive_new() calls error_report() even though
it can run within drive_init_func(), which takes an Error ** argument.
drive_init_func()'s caller main(), via qemu_opts_foreach(), is fine
with it, but clean it up anyway:
* Convert drive_new() to Error
* Update add_init_drive() to report the error received from
drive_new()
* Make main() pass &error_fatal through qemu_opts_foreach(),
drive_init_func() to drive_new()

The conversion of "xen-pci-passthrough" to realize() (commit
5a11d0f7549, v2.6.0) neglected to convert the xen_pt_config_init()
error path. If xen_pt_config_init() fails, xen_pt_realize() reports
the error, then returns success without completing its job. I don't
know the exact impact, but it can't be good.
Belatedly convert the error path.

Calling error_report() in a function that takes an Error ** argument
is suspicious. parse_numa_node() does that, and then exit()s. It
also passes &error_fatal to machine_set_cpu_numa_node(). Both wrong.
Attempting to configure numa when the machine doesn't support it kills
the VM:
$ qemu-system-x86_64 -nodefaults -S -display none -M none -preconfig -qmp stdio
{"QMP": {"version": {"qemu": {"micro": 50, "minor": 0, "major": 3}, "package": "v3.0.0-837-gc5e4e49258"}, "capabilities": []}}
{"execute": "qmp_capabilities"}
{"return": {}}
{"execute": "set-numa-node", "arguments": {"type": "node"}}
NUMA is not supported by this machine-type
$ echo $?
1
Messed up when commit 64c2a8f6d3f and 7c88e65d9e9 (v2.10.0) added
incorrect error handling right next to correct examples. Latent bug
until commit f3be67812c2 (v3.0.0) made it accessible via QMP. Fairly
harmless in practice, because it's limited to RUN_STATE_PRECONFIG.
The fix is obvious: replace error_report(); exit() by error_setg();
return.
This affects parse_numa_node()'s other caller
numa_complete_configuration(): since it ignores errors, the "NUMA is
not supported by this machine-type" is now ignored, too. But that
error is as unexpected there as any other. Change it to abort on
error instead.

When -netdev l2tpv3 fails, it first reports a specific error, then a
generic one, like this:
$ qemu-system-x86_64 -netdev l2tpv3,id=foo,src=,dst=,txsession=1
qemu-system-x86_64: -netdev l2tpv3,id=foo,src=,dst=,txsession=1: l2tpv3_open : could not resolve src, errno = Name or service not known
qemu-system-x86_64: Device 'l2tpv3' could not be initialized
With the command line, the messages go to stderr. In HMP, they go to
the monitor. In QMP, the second one becomes the error reply, and the
first one goes to stderr.
Convert net_init_tap() to Error. This suppresses the unwanted second
message, and makes the specific error the QMP error reply.

Calling error_report() in a function that takes an Error ** argument
is suspicious. save_snapshot() and load_snapshot() do that, and then
fail without setting an error. Wrong. The HMP commands survive this
unscathed, since hmp_handle_error() does nothing when no error has
been set. Callers main() (on behalf of -loadvm) and
replay_vmstate_init() crash, but I'm not sure the error is possible
there.

The previous commit changed vfio's warning messages from
vfio warning: DEV-NAME: Could not frobnicate
to
warning: vfio DEV-NAME: Could not frobnicate
To match this change, change error messages from
vfio error: DEV-NAME: On fire
to
vfio DEV-NAME: On fire
Note the loss of "error". If we think marking error messages that way
is a good idea, we should mark *all* error messages, i.e. make
error_report() print it.

The vfio code reports warnings like
error_report(WARN_PREFIX "Could not frobnicate", DEV-NAME);
where WARN_PREFIX is defined so the message comes out as
vfio warning: DEV-NAME: Could not frobnicate
This usage predates the introduction of warn_report() & friends in
commit 97f40301f1d. It's time to convert to that interface. Since
these functions already prefix the message with "warning: ", replace
WARN_PREFIX by VFIO_MSG_PREFIX, so the messages come out like
warning: vfio DEV-NAME: Could not frobnicate
The next commit will replace ERR_PREFIX.
