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.

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.

Commit v6.4.0-61-g201bd5db63 started to fill the default value for
//cpu/@migratable attribute according to QEMU support. However, active
domains either have the migratable attribute already set or the
capabilities we use for checking the QEMU support were created by older
libvirt which didn't probe for this specific capability. Thus we should
leave active domains alone when parsing their XMLs.

The 'libvirt-tmp-activewrite' bitmap is added during the 'pivot'
operation of block copy and active layer block commit operations
regardless of whether there are any bitmaps to merge, but was not
removed unless a bitmap was merged. This meant that subsequent attempts
to merge into the same image would fail.
Fix it by checking whether the 'libvirt-tmp-activewrite' would be used
by the code and don't skip the code which would delete it.
This is a regression introduced when we switched to the new code for
block commit in <20a7abc2d2d> and for block copy in <7bfff40fdfe5>. The
actual bug originates from <4fa8654ece>.

When doing a block copy, there is another chain of images attached to a

Reviewed-by: Eric Blake <eblake@redhat.com>
The index returned by qemuDomainDiskLookupByNodename is the position in
the backing chain rather than the index we report in the XML.
Since with -blockdev they differ now and additionally the disk source
also has an index we need to fix the 'threshold' events we report:
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.

This partially reverts commit 5331c4804f4f419b9e75741084f926e52413d3a1.
The original commit mistakenly thought virFileCacheLookup did not set
an error. In fact the only case it doesn't set an error for is when
the cache key is NULL. This in fact the fault of the caller for passing
an invalid cache key, so doesn't need to be handled.
This caller bug was fixed by checking for a NULL binary in the
virQEMUCapsCacheLookupDefault method.
