It turns out that one-bit filtering makes it hard to select the inverse

omitting all bits within a group means the group is not used for
filtering, and by definition of a group (each snapshot matches exactly
one bit within the group, and the set of bits in the group covers all
snapshots), selecting all bits also makes the group useless.
Unfortunately, virDomainSnapshotListChildren defined the bit
VIR_DOMAIN_SNAPSHOT_LIST_DESCENDANTS as an expansion rather than a
filter, so we cannot make it part of a filter group, so that bit
(and its counterpart VIR_DOMAIN_SNAPSHOT_LIST_ROOTS for
virDomainSnapshotList) remains a single control bit.
* include/libvirt/libvirt.h.in (virDomainSnapshotListFlags): Add a
couple more flags.
* src/libvirt.c (virDomainSnapshotNum)
(virDomainSnapshotNumChildren): Document them.
(virDomainSnapshotListNames, virDomainSnapshotListChildrenNames):
Likewise, and add thread-safety caveats.
* src/conf/virdomainlist.h (VIR_DOMAIN_SNAPSHOT_FILTERS_*): New
convenience macros.
* src/conf/domain_conf.c (virDomainSnapshotObjListCopyNames)
(virDomainSnapshotObjListCount): Support the new flags.

ACK.

I'll try to polish and repost the virDomainListAll series ASAP so that
the dependencies are satisfied.
