qapi: Move include/qapi/qmp/ to include/qobject/

The general expectation is that header files should follow the same
file/path naming scheme as the corresponding source file. There are
various historical exceptions to this practice in QEMU, with one of
the most notable being the include/qapi/qmp/ directory. Most of the
headers there correspond to source files in qobject/.

This patch corrects most of that inconsistency by creating
include/qobject/ and moving the headers for qobject/ there.

This also fixes MAINTAINERS for include/qapi/qmp/dispatch.h:
scripts/get_maintainer.pl now reports "QAPI" instead of "No
maintainers found".

block: Add blockdev-set-active QMP command

The system emulator tries to automatically activate and inactivate block
nodes at the right point during migration. However, there are still
cases where it's necessary that the user can do this manually.

Images are only activated on the destination VM of a migration when the
VM is actually resumed. If the VM was paused, this doesn't happen
automatically. The user may want to perform some operation on a block
device (e.g. taking a snapshot or starting a block job) without also
resuming the VM yet. This is an example where a manual command is
necessary.

Another example is VM migration when the image files are opened by an
external qemu-storage-daemon instance on each side. In this case, the
process that needs to hand over the images isn't even part of the
migration and can't know when the migration completes. Management tools
need a way to explicitly inactivate images on the source and activate
them on the destination.

This adds a new blockdev-set-active QMP command that lets the user
change the status of individual nodes (this is necessary in
qemu-storage-daemon because it could be serving multiple VMs and only
one of them migrates at a time). For convenience, operating on all
devices (like QEMU does automatically during migration) is offered as an
option, too, and can be used in the context of single VM.

block: Inactivate external snapshot overlays when necessary

Putting an active block node on top of an inactive one is strictly
speaking an invalid configuration and the next patch will turn it into a
hard error.

However, taking a snapshot while disk images are inactive after
completing migration has an important use case: After migrating to a
file, taking an external snapshot is what is needed to take a full VM
snapshot.

In order for this to keep working after the later patches, change
creating a snapshot such that it automatically inactivates an overlay
that is added on top of an already inactive node.

backup: add minimum cluster size to performance options

In the context of backup fleecing, discarding the source will not work
when the fleecing image has a larger granularity than the one used for
block-copy operations (can happen if the backup target has smaller
cluster size), because cbw_co_pdiscard_snapshot() will align down the
discard requests and thus effectively ignore then.

To make @discard-source work in such a scenario, allow specifying the
minimum cluster size used for block-copy operations and thus in
particular also the granularity for discard requests to the source.

[active disk] [temp.img]

In this case discard-after-copy does two things:

- discard data in temp.img to save disk space
- avoid further copy-before-write operation in discarded area

Note that we have to declare WRITE permission on source in
copy-before-write filter, for discard to work. Still we can't take it
unconditionally, as it will break normal backup from RO source. So, we
have to add a parameter and pass it thorough bdrv_open flags.

blockdev: Fix blockdev-snapshot-sync error reporting for no medium

When external_snapshot_abort() rejects a BlockDriverState without a
medium, it creates an error like this:

error_setg(errp

blockdev: Fix blockdev-snapshot-sync error reporting for no medium

When external_snapshot_abort() rejects a BlockDriverState without a
medium, it creates an error like this:

error_setg(errp, "Device '%s' has no medium", device);

Trouble is @device can be null. My system formats null as "(null)",
but other systems might crash. Reproducer:

1. Create a block device without a medium

-> {"execute": "blockdev-add", "arguments": {"driver": "host_cdrom", "node-name": "blk0", "filename": "/dev/sr0"}}
<- {"return": {}}

3. Attempt to snapshot it

-> {"execute":"blockdev-snapshot-sync", "arguments": { "node-name": "blk0", "snapshot-file":"/tmp/foo.qcow2","format":"qcow2"}}
<- {"error": {"class": "GenericError", "desc": "Device '(null)' has no medium"}}

Broken when commit 0901f67ecdb made @device optional.

Use bdrv_get_device_or_node_name() instead. Now it fails as it
should:

<- {"error": {"class": "GenericError", "desc": "Device 'blk0' has no medium"}}

blockdev: Fix block_resize error reporting for op blockers

When block_resize() runs into an op blocker, it creates an error like
this:

error_setg(errp, "Device '%s' is in use", device);

Trouble is @device can be null. My system formats null as "(null)",
but other systems might crash. Reproducer:

1. Create two block devices

-> {"execute": "blockdev-add", "arguments": {"driver": "file", "node-name": "blk0", "filename": "64k.img"}}
<- {"return": {}}
-> {"execute": "blockdev-add", "arguments": {"driver": "file", "node-name": "blk1", "filename": "m.img"}}
<- {"return": {}}

2. Put a blocker on one them

-> {"execute": "blockdev-mirror", "arguments": {"job-id": "job0", "device": "blk0", "target": "blk1", "sync": "full"}}
{"return": {}}
-> {"execute": "job-pause", "arguments": {"id": "job0"}}
{"return": {}}
-> {"execute": "job-complete", "arguments": {"id": "job0"}}
{"return": {}}

Note: job events elided for brevity.

3. Attempt to resize

-> {"execute": "block_resize", "arguments": {"node-name": "blk1", "size":32768}}
<- {"error": {"class": "GenericError", "desc": "Device '(null)' is in use"}}

Broken when commit 3b1dbd11a60 made @device optional. Fixed in commit
ed3d2ec98a3 (block: Add errp to b{lk,drv}_truncate()), except for this
one instance.

Fix it by using the error message provided by the op blocker instead,
so it fails like this:

<- {"error": {"class": "GenericError", "desc": "Node 'blk1' is busy: block device is in use by block job: mirror"}}

Fixes: 3b1dbd11a60d (qmp: Allow block_resize to manipulate bs graph nodes.)

stream: Allow users to request only format driver names in backing file format

Introduce a new flag 'backing-mask-protocol' for the block-stream QMP
command which instructs the internals to use 'raw' instead of the
protocol driver in case when a image is used without a dummy 'raw'
wrapper.

The flag is designed such that it can be always asserted by management
tools even when there isn't any update to backing files.

The flag will be used by libvirt so that the backing images still
reference the proper format even when libvirt will stop using the dummy
raw driver (raw driver with no other config). Libvirt needs this so that
the images stay compatible with older libvirt versions which didn't
expect that a protocol driver name can appear in the backing file format
field.

commit: Allow users to request only format driver names in backing file format

Introduce a new flag 'backing-mask-protocol' for the block-commit QMP
command which instructs the internals to use 'raw' instead of the
protocol driver in case when a image is used without a dummy 'raw'
wrapper.

The flag is designed such that it can be always asserted by management
tools even when there isn't any update to backing files.

The flag will be used by libvirt so that the backing images still
reference the proper format even when libvirt will stop using the dummy
raw driver (raw driver with no other config). Libvirt needs this so that
the images stay compatible with older libvirt versions which didn't
expect that a protocol driver name can appear in the backing file format
field.

block: remove bdrv_co_lock()

The bdrv_co_lock() and bdrv_co_unlock() functions are already no-ops.

There isn't a clean way to split this patch and the reviewers are likely
the same group of people, so I decided to do it in one patch.
