The new value tapfd enables removing slirp4netns features. Rather than having it figure out where to create a tap network, the opened tap file descriptor can now be inherited to slirp4netns and used as is. This removes the need for forking and attaching a namespace as well as readiness communication, but it also removes the ability to choose the name of the network interface or configuring it.
