[PATCH 2/2] Reload snapshots on SIGHUP

[Philipp Hahn <hahn@xxxxxxxxxxxxx>]

On receiving SIGHUP, libvirtd currently only reloads all persistent
configs for qemu domains, but fails to reload the associated snapshot
data.

Copy code from qemudStartup() to qemudReload() to iterate over all
domains and call qemuDomainSnapshotLoad() for every domain.

This depends on commits 9e093f0b4cc5a5fc455a4893d73dc0f2c5355161 to fix
SIGHUP and on 839a5295ef568727b025f9546c1720279f49fe62 to fix a memory
leak.
