Details:

Assume such scenario:
- screen is built with pipes/fifos support (default in 4.0.x)
- some sessions are started and detached
- screen is updated to git version (or in future some 4.1.x release).
git/4.1.x uses sockets now by default (commit
b4aa8750b45e7b75ab5a837503dc0a6b2e177bf9)

Now you won't be able to reattach pipe/fifo sessions because socket version
understands socket only. This breaks upgrade path.

What IMO should be done is to have screen undestand both - fifos and sockets
at runtime but only create the one being "default".

So for new sessions socket would be used but screen would still be able to
reattach fifo based sessions.
