* new APIs
get_parent(self, domname, snapname, flag = 0)
children_num(self, domname, snapname, flag)
children_names_list(self, domname, snapname, flag)
the flag in children_num and children_names_list could be in 0-7,
which is the OR operation result of
(VIR_DOMAIN_SNAPSHOT_LIST_DESCENDANTS |
VIR_DOMAIN_SNAPSHOT_LIST_METADATA |
VIR_DOMAIN_SNAPSHOT_LIST_LEAVES)
* deleted redundancy spaces and fixed a typo in function domain()
* getConnect(), getDomain() and getName() API are not added in,
current snapshotAPI requires user to offer connection obj, domain
name and snapshot name.
