This makes string can be transported between client and server.
For compatibility,
o new server should not send strings to old client if it
doesn't see the flag VIR_DOMAIN_TYPED_STRING_OKAY.
o new client that wants to be able to send/receive strings
should always set the flag VIR_DOMAIN_TYPED_STRING_OKAY;
if it is rejected by a old server that doesn't understand
VIR_DOMAIN_TYPED_STRING_OKAY, then the client should have
a second try with out flag VIR_DOMAIN_TYPED_STRING_OKAY
to cope with an old server.
Ideas of compatibility are coming from Eric, thanks.
