[libvirt] [PATCH 06/11] Separate internal node suspend APIs from public API



From: "Daniel P. Berrange" <berrange redhat com>

The individual hypervisor drivers were directly referencing
APIs in virnodesuspend.c in their virDriverPtr struct. Separate
these methods, so there is always a wrapper in the hypervisor
driver. This allows the unused virConnectPtr args to be removed
from the virnodesuspend.c file. Again this will ensure that
ACL checks will only be performed on invocations that are
directly associated with public API usage.
