Could it be GIOChannel simply?

1) Chardev is already mostly a wrapper around GIOChannel

2) NBD and VNC could be converted to GIOChannel with relative ease

3) migration is more complicated because (unlike everything else) it
uses a separate thread and blocking sockets, but you could probably
write a GIOChannel-based implementation of QEMUFile.

I found a GIOChannel wrapper for gnutls at
https://github.com/aldebaran/connman/blob/master/gweb/giognutls.c.  It's
not the right license for QEMU (GPLv2-only) but it's only 400 lines of
code.  If necessary I can help with clean-room reverse engineering.
