Meson doesn't use .libs directory, everything is placed directly into
directories where meson.build file is used.
In order to have working tests and running libvirt directly from GIT we
need to fix all the paths pointing '.libs' directory.

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
directory.

EXTRA_DIST is not relevant because meson makes a git copy when creating

The remaining ones are not converted to meson files as they are

Pass the scheduler element name instead of trying to reconstructing
it from the attribute name.
This has the benefit of not mixing '%s' with regular text in
translatable strings as well as preventing the confusion when
the 's' marking the plural in the element name ('vcpus') is taken
as a first letter of the 'sched' suffix.

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).

The storage pool code now attempts to disable COW by default on btrfs,
but management applications may wish to override this behaviour. Thus we
introduce a concept of storage pool features:
<features>
<cow state='yes|no'/>
</features>
If the <cow> feature policy is set, it will be enforced. It will always
return an hard error if COW cannot be explicitly set or unset.
