The QObject input visitor has three error message formats:
* Parameter '%s' is missing
* "Invalid parameter type for '%s', expected: %s"
* "QMP input object member '%s' is unexpected"
The '%s' are member names (or "null", but I'll fix that later).
The last error message calls the thing "QMP input object member"
instead of "parameter". Misleading when the visitor is used on
QObjects that don't come from QMP. Change it to "Parameter '%s' is
unexpected".

The QERR_ macros are leftovers from the days of "rich" error objects.
QERR_QMP_BAD_INPUT_OBJECT, QERR_QMP_BAD_INPUT_OBJECT_MEMBER,
QERR_QMP_EXTRA_MEMBER are used in just one place now, except for one
use that has crept into qobject-input-visitor.c.
Drop these macros, to make the (bad) error messages more visible.

qmp_check_input_obj() duplicates qmp_dispatch_check_obj(), except the
latter screws up an error message. handle_qmp_command() runs first
the former, then the latter via qmp_dispatch(), masking the screwup.
qemu-ga also masks the screwup, because it also duplicates checks,
just differently.
qmp_check_input_obj() exists because handle_qmp_command() needs to
examine the command before dispatching it. The previous commit got
rid of this need, except for a tracepoint, and a bit of "id" code that
relies on qdict not being null.
Fix up the error message in qmp_dispatch_check_obj(), drop
qmp_check_input_obj() and the tracepoint. Protect the "id" code with
a conditional.

The value of key 'arguments' must be a JSON object. qemu-ga neglects
to check, and crashes. To reproduce, send
{ 'execute': 'guest-sync', 'arguments': [] }
to qemu-ga.
do_qmp_dispatch() uses qdict_get_qdict() to get the arguments. When
not a JSON object, this gets a null pointer, which flows through the
generated marshalling function to qobject_input_visitor_new(), where
it fails the assertion. qmp_dispatch_check_obj() needs to catch this
error.
QEMU isn't affected, because it runs qmp_check_input_obj() first,
which basically duplicates qmp_dispatch_check_obj()'s checks, plus the
missing one.
Fix by copying the missing one from qmp_check_input_obj() to
qmp_dispatch_check_obj().

by QAPI in blockdev-add:

auth method: either 'cephx' or 'none'
The "server" and "auth-supported" QAPI parameters are arrays. To conform
with the rados API, the array items are join as a single string with a ';'
character as a delimiter when setting the configuration values.

Management tools need to be able to know about every node in the graph
and need a way to address them. Changing the graph structure was okay
because libvirt doesn't really manage the node level yet, but future
libvirt versions need to deal with both new and old version of qemu.
This new option to blockdev-commit allows the client to set a node-name
for the automatically inserted filter driver, and at the same time
serves as a witness for a future libvirt that this version of qemu does
automatically insert a filter driver.

Change the qemu_strtosz() & friends to return -EINVAL when @endptr is
null and the conversion doesn't consume the string completely.
Matches how qemu_strtol() & friends work.
Only test_qemu_strtosz_simple() passes a null @endptr. No functional
change there, because its conversion consumes the string.
Simplify callers that use @endptr only to fail when it doesn't point
to '\0' to pass a null @endptr instead.
