sockets: helper functions for qemu (Gerd Hoffman)

This patch creates a new source file qemu-sockets.c with a bunch of
helper functions to create listening and connected sockets.

New features of this code are (a) support for searching for a free
port in a given range and (b) support for IPv6.

The following patches put that code into use.
