[PATCH] lib: Prohibit parallel connections with tunneled migration
As discussed on the developer list, parallel migration connections
are not compatible with tunneled migration
https://www.redhat.com/archives/libvir-list/2020-January/msg00463.html
Prohibit the concurrent use of parallel and tunneled migration options.

I added the check to all migration entry points except virDomainMigrate3,
where the p2p and tunneled options are already prohibitied.
