We will need to keep some QEMU-specific data for each CPU model
supported by a QEMU binary. Instead of complicating the generic
virDomainCapsCPUModelsPtr, we can just directly store
qemuMonitorCPUDefsPtr returned by the capabilities probing code.

The function would return a valid virDomainCapsCPUModelsPtr with empty
CPU models list if query-cpu-definitions exists in QEMU, but returns
GenericError meaning it's not in fact implemented. This behaviour is a
bit strange especially after such virDomainCapsCPUModels structure is
stored in capabilities XML and parsed back, which will result in NULL
virDomainCapsCPUModelsPtr rather than a structure containing nothing.
Let's just keep virDomainCapsCPUModelsPtr NULL if the QMP command is not
implemented and change the return value to int so that callers can
easily check for failure or success.

Rather than returning a direct pointer the list stored in qemuCaps the

Another weird bug appeared concerning qemu namespaces. Basically
the problem is as follows:
1) Issue an API that causes libvirt to create a node in domain's
namespace, say /dev/nvme0n1 with 8:0 as major:minor (the API can
be attach-disk for instance). Or simply create the node from a
console by hand.
2) Detach the disk from qemu.
3) Do something that makes /dev/nvme0n1 change it's minor number.
4) Try to attach the disk again.
The problem is, in a few cases - like disk-detach - we don't
remove the corresponding /dev node from the mount namespace
(because it may be used by some other disk's backing chain). But
this creates a problem, because if the node changes its MAJ:MIN
numbers we don't propagate the change into the domain's
namespace. We do plain mknod() and ignore EEXIST which obviously
is not enough because it doesn't guarantee that the node has
updated MAJ:MIN pair.

When dispatching a message read from client it is first passed
through registered filters. If one of the filters consumes the
message no further processing of the message is done. However,
the filter callbacks are called with the client object locked.
This breaks lock ordering in case of virStream filter, we always
acquire stream private data lock without the client object
locked. In other words, the daemonStreamFilter() does not follow
