Allow setting socket/tcp options for server sockets.

[timgws]

This patch will enable users to set options such as SO_REUSEADDR and TCP_NODELAY on new sockets that are created before being passed to the connection emitter.

nodejs by default sets TCP_NODELAY and SO_REUSEADDR to true. I wanted an easy way to replicate this behaviour in my PHP application, so I added the setTCPOption and setSocketOption functions to enable these options to be set.

I like the API and the feature.

One more thing I'd like to see is error handling. socket_set_option returns false if the option can't be applied. Could you check the return type and emit and error if that happens?

Thanks for the PR @timgws and the elaborate README!

I'm a bit surprised this appears to use socket_set_option() (from ext-sockets) on stream socket resources. Could you provide some info on which platforms has this been tested on?

I think you'll find it is necessary to do:
$real_socket = socket_import_stream($socket);
socket_set_option($real_socket, ...);
(on Windows at least you can't just call socket_set_option on a stream resource)

Thanks for your effort and filing this PR, but unfortunately we've never been able to get this to work properly.

I believe some of this may have been resolved via #64 in the meantime.

As such, I'm closing this due to a lack of feedback for now. If you feel this is still relevant, please comment on this and we can reopen this 👍
