network: Add virNetworkObj Get/Set API's for @dnsmasqPid and @radvdPid
In preparation for making the object private, create/use a couple of API's to get/set the obj->dnsmasqPid and obj->radvdPid. NB: Since the pid's can sometimes changed based on intervening functions, be sure to always fetch the latest value. Signed-off-by: John Ferlan <jferlan@redhat.com>
