qapi: place outermost object on qiv stack
This is a slight change in the implementation of QMPInputVisitor
that helps when adding strict mode.
Const QObjects cannot be inc/decref-ed, and that's why QMPInputVisitor
relies heavily on weak references to inner objects. I'm not removing
the weak references now, but since refcount+const is a lost battle in C
(C++ has "mutable") I think removing const is fine in this case.

qapi: untangle next_list
Right now, the semantics of next_list are complicated. The caller must:
* call start_list
* call next_list for each element *including the first*
* on the first call to next_list, the second argument should point to
NULL and the result is the head of the list. On subsequent calls,
the second argument should point to the last node (last result of
next_list) and next_list itself tacks the element at the tail of the
list.
This works for both input and output visitor, but having the visitor
write memory when it is only reading the list is ugly. Plus, relying
on *list to detect the first call is tricky and undocumented.
We can initialize so->entry in next_list instead of start_list, leaving
it NULL in start_list. This way next_list sees clearly whether it is
on the first call---as a bonus, it discriminates the cases based on
internal state of the visitor rather than external state. We can
also pull the assignment of the list head from generated code up to
next_list.

$ grep Tibor qemu-doc.texi
by Tibor "TS" Schütz.
$ man ./qemu.1 | grep Tibor
by Tibor "TS" SchA~Xtz.
This patch allows utf8 in man/pod docs.
Initially it was split into two parts and sent on 2012-02-02.
Resending it again (3rd time) now in merged form. If any
other generalizations of $(POD2MAN) are needed it can be done
in a separate patch. Current form of $(POD2MAN) is choosen
to be able to easily change it if some implementation does
not support utf8 or resulting output has issues with local
man(1) program/macros.
First, add @documentencoding in scripts/texi2pod.pl:
Currently our texi2pod ignores @documentencoding even if it is set
properly in *.texi files. This results in a mojibake in documents
generated from qemu.pod (which is generated from qemu-doc.texi by
texi2pod), because the rest of the tools assumes ASCII encoding.
This patch recognizes first @documentencoding in input and places
it at the beginning of output as =encoding directive.
Second, run pod2man with --utf8 option to enable utf8 in manpages:
This option makes no difference for manpages which contains only
ascii chars. But for manpages with actual UTF8 characters (qemu
docs contains these), this change allows to see real characters
instead of mojibakes or substitutes.

bit is 1, and it is cast to a intptr_t and then to uint64_t, such

surface.mem = (intptr_t)ssd->buf;
This causes the sign bit to be extended which causes a wrong address to

Introduce "xen-save-devices-state"
- add an "is_ram" flag to SaveStateEntry;
- register_savevm_live sets is_ram for live_savevm devices;
- introduce a "xen-save-devices-state" QAPI command that can be used to save
the state of all devices, but not the RAM or the block devices of the
VM.
Changes in v8:
- rename save-devices-state to xen-save-devices-state.
Changes in v7:
- rename save_devices to save-devices-state.
Changes in v6:
- remove the is_ram parameter from register_savevm_live and sets is_ram
if the device is a live_savevm device;
- introduce save_devices as a QAPI command, write a better description
for it;
- fix CODING_STYLE;
- introduce a new doc to explain the save format used by save_devices.

This commit is more or less obvious. What it caused is less obvious:
SCSI CD drives failed to eject under Linux, though for example the

The actual chain of events is quite complex and somehow involves

spice-core.c which registered both a type initializer and a machine
