Considering 'id' is mandatory for user_creatable objects/backends
and user_creatable_add_type() always has it as an argument
regardless of where from it is called CLI/monitor or QMP,
Fix issue by adding 'id' property to hostmem backends and
set it in user_creatable_add_type() for every object that
implements 'id' property. Then later at query-memdev time
get 'id' from object directly.

This patch implements VHOST_USER_PROTOCOL_F_NET_MTU
protocol feature and VHOST_USER_NET_SET_MTU request so
that the backend gets notified of the user defined host
MTU.
If backend supports VHOST_USER_PROTOCOL_F_REPLY_ACK,
QEMU assumes MTU is valid if success is returned.
Vhost-net driver sends this request through a new
vhost_net_set_mtu vhost_ops entry.

This patch adds support of recording and replaying network packets in
irount rr mode.
Record and replay for network interactions is performed with the network filter.
Each backend must have its own instance of the replay filter as follows:
-netdev user,id=net1 -device rtl8139,netdev=net1
-object filter-replay,id=replay,netdev=net1
Replay network filter is used to record and replay network packets. While
recording the virtual machine this filter puts all packets coming from
the outer world into the log. In replay mode packets from the log are
injected into the network device. All interactions with network backend
in replay mode are disabled.

Because TFTP does not support byte ranges, it was never usable with our
curl block driver. Since apparently nobody has ever complained loudly
enough for someone to take care of the issue until now, it seems
reasonable to assume that nobody has ever actually used it.
Therefore, it should be safe to just drop it from curl's protocol list.
[Jeff Cody: Below is additional summary pulled, with some rewording,
from followup emails between Max and Markus, to explain what
worked and what didn't]
TFTP would sometimes work, to a limited extent, for images <= the curl
"readahead" size, so long as reads started at offset zero. By default,
that readahead size is 256KB.
Reads starting at a non-zero offset would also have returned data from a
zero offset. It can become more complicated still, with mixed reads at
zero offset and non-zero offsets, due to data buffering.
In short, TFTP could only have worked before in very specific scenarios
with unrealistic expectations and constraints.

We leave users to choose whatever heartbeat solution they want,
if the heartbeat is lost, or other errors they detect, they can use
experimental command 'x_colo_lost_heartbeat' to tell COLO to do failover,
COLO will do operations accordingly.
For example, if the command is sent to the Primary side,
the Primary side will exit COLO mode, does cleanup work,
and then, PVM will take over the service work. If sent to the Secondary side,
the Secondary side will run failover work, then takes over PVM's service work.

This is the first step towards having fine-grained critical sections in
dataplane threads, which will resolve lock ordering problems between
address_space_* functions (which need the BQL when doing MMIO, even
after we complete RCU-based dispatch) and the AioContext.
Because AioContext does not use contention callbacks anymore, the
unit test has to be changed.

The QmpInputVisitor has no direct dependency on QMP. It is
valid to use it anywhere that one has a QObject. Rename it
to better reflect its functionality as a generic QObject
to QAPI converter.
The previous commit renamed the files, this one renames C identifiers.

Now that QAPI supports boxed types, we can have unions at the top level
of a command, so let's put our real options directly there for
blockdev-add instead of having a single "options" dict that contains the
real arguments.
blockdev-add is still experimental and we already made substantial
changes to the API recently, so we're free to make changes like this
one, too.

This introduces load-acquire and store-release operations in QEMU.
For now, just use them as an implementation detail of atomic_mb_read
and atomic_mb_set.
Since docs/atomics.txt documents that atomic_mb_read only synchronizes
with an atomic_mb_set of the same variable, we can use the new implementation
everywhere instead of seq-cst loads and stores.

This patch does three things:
- It adds a list of restrictions and ToDos
- It corrects the header --- lines to match the length of the header
- It clarifies the force-raw option

Mark the old commands 'migrate_set_speed' and 'migrate_set_downtime' as
deprecated.
Move max-bandwidth and downtime-limit into migrate-set-parameters for
setting maximum migration speed and expected downtime limit parameters
respectively.
Change downtime units to milliseconds (only for new-command) and set
its upper bound limit to 2000 seconds.
Update the query part in both hmp and qmp qemu control interfaces.

The event currently only contains the BlockBackend name. However, with
anonymous BlockBackends, this is always the empty string. Add the qdev
ID (or if none was given, the QOM path) so that the user can still see
which device caused the event.
Event generation has to be moved from bdrv_eject() to the BlockBackend
because the BDS doesn't know the attached device, but that's easy
because blk_eject() is the only user of it.
