libvirt/daemon/remote.c
Erik Skultety 8cd1d546e6 util: Export remoteSerializeTypedParameters internally via util 
Same as for deserializer, this method might get handy for admin one day.
The major reason for this patch is to stay consistent with idea, i.e.
when deserializer can be shared, why not serializer as well. The only
problem to be solved was that the daemon side serializer uses a code
snippet which handles sparse arrays returned by some APIs as well as
removes any string parameters that can't be returned to older clients.
This patch makes of the new virTypedParameterRemote datatype introduced
by one of the pvious patches.
