block: Accept node-name for block-stream
In order to remove the necessity to use BlockBackend names in the
external API, we want to allow node-names everywhere. This converts
block-stream to accept a node-name without lifting the restriction that
we're operating at a root node.
In case of an invalid device name, the command returns the GenericError
error class now instead of DeviceNotFound, because this is what
qmp_get_root_bs() returns.

As libvirt makes use of the DeviceNotFound error class, we must add

returns GenericErrors.

nbd-server: Use a separate BlockBackend
The builtin NBD server uses its own BlockBackend now instead of reusing
the monitor/guest device one.
This means that it has its own writethrough setting now. The builtin
NBD server always uses writeback caching now regardless of whether the
guest device has WCE enabled. qemu-nbd respects the cache mode given on
the command line.
We still need to keep a reference to the monitor BB because we put an
eject notifier on it, but we don't use it for any I/O.

nbd-server: Allow node name for nbd-server-add
There is no reason why an NBD server couldn't be started for any node,
even if it's not on the top level. This converts nbd-server-add to
accept a node-name.
Note that there is a semantic difference between using a BlockBackend
name and the node name of its root: In the former case, the NBD server
is closed on eject; in the latter case, the NBD server doesn't drop its
reference and keeps the image file open this way.

block/io: reuse bdrv_co_pwritev() for write compressed
For bdrv_pwrite_compressed() it looks like most of the code creating
coroutine is duplicated in bdrv_prwv_co(). So we can just add a flag
(BDRV_REQ_WRITE_COMPRESSED) and use bdrv_prwv_co() as a generic one.
In the end we get coroutine oriented function for write compressed by using
bdrv_co_pwritev/blk_co_pwritev with BDRV_REQ_WRITE_COMPRESSED flag.

block: simplify drive-backup
Now that we can support boxed commands, use it to greatly reduce the
number of parameters (and likelihood of getting out of sync) when
adjusting drive-backup parameters.

drive-backup: added support for data compression
The idea is simple - backup is "written-once" data. It is written block
by block and it is large enough. It would be nice to save storage
space and compress it.
The patch adds a flag to the qmp/hmp drive-backup command which enables
block compression. Compression should be implemented in the format driver
to enable this feature.
There are some limitations of the format driver to allow compressed writes.
We can write data only once. Though for backup this is perfectly fine.
These limitations are maintained by the driver and the error will be
reported if we are doing something wrong.

test-coroutine: Fix coroutine pool corruption
The test case overwrites the Coroutine object with 0xff as a way to
assert that the coroutine isn't used any more. However, this means that
the coroutine pool now contains a corrupted object and later test cases
may get this corrupted object and crash.
This patch saves the real content of the object and restores it after
completing the test. The only use of the coroutine pool between those
two points is the deletion of co2. As this only means an insertion at
the head of an SLIST (release_pool or alloc_pool), it doesn't access the
invalid list pointers that co1 has during this period.

coroutine: Let CoMutex remember who holds it
In cases of deadlocks, knowing who holds a given CoMutex is really
helpful for debugging. Keeping the information around doesn't cost much
and allows us to add another assertion to keep the code correct, so
let's just add it.

coroutine: Assert that no locks are held on termination
A coroutine that takes a lock must also release it again. If the
coroutine terminates without having released all its locks, it's buggy
and we'll probably run into a deadlock sooner or later. Make sure that
we don't get such cases.
