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.

testSchemaDir is a helper which invokes the schema test using virTestRun

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
the lock ordering.

Commit <f136b83139c63f20de0df3285d9e82df2fb97bfc> reworked process
affinity setting but did not take cgroups into account which introduced
an issue when starting VM with custom cpuset.cpus for the whole machine
group.
If the machine group is limited to some pCPUs libvirt should not try to
set a VM to run on all pCPUs as it will result in permission denied when
writing to cpuset.cpus.
To fix this the affinity has to be set separately from cgroups cpuset.

uint64_t. This one is explicitly aligned to 8 bytes, while
uint64_t can be aligned to 4 bytes (on 32 bits). We've used
explicit typecast to uint64_t to shut compiler which would
otherwise complain of assigning a pointer into an integer. Well,
we have uintptr_t just for that.
