With meson we no longer have .libs directory with the actual binary so
we have to take a different approach to detect if running from build
directory.
This is not as robust as for autotools because if you select --prefix
in the build directory it will incorrectly enable the override as well
but nobody should do that.
We have to modify some of the tests to not add current build path into
PATH variable and use the full path for virsh instead. Otherwise it
would be impossible to figure out that we are running virsh from build

When doing an external snapshot we migrate memory to a file as a form of
taking the memory state. This creates a problem as qemu deactivates all
active bitmaps after a successful migration. This means that calling
'query-named-block-nodes' will return an empty list of bitmaps for
devices. We use the bitmap list to propagate the active bitmaps into the
overlay files being created which is required for backups to work after
a snapshot. Since we wouldn't propagate anything a subsequent backup
will fail with:
invalid argument: missing or broken bitmap 'testchck' for disk 'vda'
To fix this, we can simply collect the bitmap list prior to the
migration.

CVE-2020-14339
When building domain's private /dev in a namespace, libdevmapper
is consulted for getting full dependency tree of domain's disks.
The reason is that for a multipath devices all dependent devices
must be created in the namespace and allowed in CGroups.
However, this approach is very fragile as building of namespace
happens in the forked off child process, after mass close of FDs
and just before dropping privileges and execing QEMU. And it so
happens that when calling libdevmapper APIs, one of them opens
/dev/mapper/control and saves the FD into a global variable. The
FD is kept open until the lib is unlinked or dm_lib_release() is
called explicitly. We are doing neither.
However, the virDevMapperGetTargets() function is called also
from libvirtd (when setting up CGroups) and thus has to be thread
safe. Unfortunately, libdevmapper APIs are not thread safe (nor
async signal safe) and thus we can't use them. Reimplement what
libdevmapper would do using plain C (ioctl()-s, /proc/devices
parsing, /dev/mapper dirwalking, and so on).

Since with -blockdev they differ now and additionally the disk source

1) If it's the top level image we must always trigger the event without
any suffix as we did until now
2) We must report the correct index
3) We must report the correct index also for the top level image, when
blockdev is used.
This means that we need to potentially emit 2 events, one for the device
without the index and then when blockdev is used and the top level image
has an index we must do it also with the index.
This will fix it for blockdev cases, while also not removing previous
semantics.
