452c2cc7e7 qemu_monitor_json: Properly check "return" type
My commit 2e0d6cdec4 claimed qemuMonitorJSONCheckError guarantees
"return" object exists in the JSON reply. But it only makes sure the key
is there, while the type of the value is not checked. A lot of callers
do not care since they only want to see whether their QMP command failed
or not, but any caller which needs to read some data from the reply
wants to make sure the correct data type was returned.

This patch adds a new API called qemuMonitorJSONCheckReply which calls
qemuMonitorJSONCheckError and checks "return" contains a value of the
specified type.

ea520f6b67 util: json: Fix freeing of objects appended to virJSONValue
It was not possible to determine whether virJSONValueObjectAddVArgs and
the functions using it would consume a virJSONValue or not when used
with the 'a' or 'A' modifier depending on when the loop failed.

Fix this by passing in a pointer to the pointer so that it can be
cleared once it's successfully consumed and the callers don't have to
second-guess leaving a chance of leaking or double freeing the value
depending on the ordering.

Fix all callers to pass a double pointer too.

When GIC support was introduced (QEMU 2.6 timeframe) we needed
to make sure both GICv2 hardware and GICv3 hardware were handled
correctly, and that was achieved by having separate capabilities
data for each.

Now that we have capabilities data for several QEMU versions we
can stop storing data for GICv2 and GICv3 hardware separately,
and instead have GICv2 data for QEMU <= 2.10 and GICv3 data for
QEMU >= 2.12, without losing any coverage.

da1ade7a52 remote: remove some __sun conditionals
The libvirtd daemon has some arbitrary logic to drop privileges, but
only on Solaris platforms. This was added during Xen days, when Xen was
the only driver running in libvirtd. There's no expectation or testing
that this works with the new libxl stack, nor whether dropping
privileges breaks any of the secondary drivers. Finally, we'll be
splitting drivers out into their own independant daemons, so this won't
be applicable to libvirtd in future anyway.

The remote driver client meanwhile arbitrarily disables daemon
auto-spawn when connecting as non-root, breaking a key feature of
libvirt unprivileged connections.

Since we've not had any contributions for Solaris since circa 2012
and we don't do any CI testing we should consider this platform
unmaintained and thus reasonable to remove this cruft. If someone steps
forward to maintain Solaris again, this code would need re-evaluating to
come up with something more targetted.

There's various __sun conditionals in the Xen driver code, but those are
not touched. This is all for the legacy Xen driver, which will be
entirely removed at some point in future, so not benefit to hacking out
just the Solaris parts.
