list: new helper function to collect snapshots
Wraps the conversion from 'char *name' to virDomainSnapshotPtr in a reusable manner. * src/conf/virdomainlist.h (virDomainListSnapshots): New declaration. * src/conf/virdomainlist.c (virDomainListSnapshots): Implement it. * src/libvirt_private.syms (virdomainlist.h): Export it.
