We already have a way for a single RDP client connection to be passed from a parent process to a child using a combination of environment variable (RDP_FD) and env var (--env-socket) This patch allows a bound socket fd (as opposed to a client connection) to be established in a parent process and provided to the rdp backend. WSLg uses this to set up an AF_VSOCK socket for communication between a Windows RDP client and a weston compositor running under a hypervisor.
