tools/virsh.c: Remove vshNameSorter for nobody uses it
tools/virsh-secret.c:
* vshSecretSorter to sort secret object by name
* vshSecretListFree to free the secret objects list.
* vshSecretListCollect to collect the secret objects, trying to use
new API first, fall back to older APIs if it's not supported.
