* tools/virsh.c (malloc, calloc, realloc, strdup): Enforce that
within this file, we use the safe vsh wrappers instead.
(cmdNodeListDevices, cmdSnapshotCreate, main): Fix violations of
this policy.
---
Hmm, I also noticed that we're inconsistent on strdup/vshStrdup in
this file; separate cleanup patch for that coming up soon.
The bulk of this patch is code motion.
