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.

EXTRA_DIST is not relevant because meson makes a git copy when creating
dist archive so everything tracked by git is part of dist tarball.
The remaining ones are not converted to meson files as they are
automatically tracked by meson.

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.

This calls virFileSetCOW when building a pool with a request to attempt,
but not require, COW to be disabled. The effect is that nothing changes
on non-btrfs filesystems, but btrfs will get COW disabled on the
directory. This setting is then inherited by all newly created files in
the pool, avoiding the need for mgmt app to set "nocow" on a per-volume
basis.

When disabling COW on individual files, we now use the virFileSetCOW
method. Note that this change has a slight semantic difference to the
old implementation.
The original code reported errors but returned success when disabling
COW failed.
With this new code, we will always report an error if the user requested
disabling of COW and we could not honour it, either because btrfs
returned an error, or because the filesystem is not btrfs.

kept the old alias just for API stability. Well, not anymore [2].

Previously gnulib could auto-trigger refresh when running

with the pending meson rewrite it isn't worth worrying

The intent here is to allow the virt drivers to be run directly embedded
in an arbitrary process without interfering with libvirtd. To achieve
this they need to store all their configuration & state in a separate
directory tree from the main system or session libvirtd instances.
This can be useful for doing testing of the virt drivers in "make check"
without interfering with the user's own libvirtd instances.
It can also be used for applications using KVM/QEMU as a piece of
infrastructure to build an service, rather than for general purpose
OS hosting. A long standing example is libguestfs, which would prefer
if its temporary VMs did show up in the main libvirtd VM list, because
this confuses apps such as OpenStack Nova. A more recent example would
be Kata which is using KVM as a technology to build containers.
