socket: Allow selection of TCP Congestion Avoidance algorithm to socket
Hi, attached path extends socket configurables with another knob - TCP Congestion Avoidance selection. Linux implements handful of those, useful in various situations. For example, TCP Low Priority may be used by FTP service to gracefully yield bandwidth for more important TCP/IP streams. Until recently TCP_CONGESTION was Linux-specific, recently FreeBSD 8 and OpenSolaris gained compatible support.
