std.stdio.openNetwork should be moved to different place

While I think it is useful in principle, it should not be in std.stdio.

It causes any program importing std.stdio, to link to network stack including functions like gethostname, which with most libc will cause issues with static linking.

It also slows down all the std.stdio imports for everybody, while maybe 0.001% of people actually us that function.

A much better approach would be to have a function that accepts a TCP socket, and converts it to std.stdio.File.

Such function should be in own module, like std.socket.file, or something like this.

This way user is in a control of all connection settings, and function does just one thing.

Right now openNetwork is too hermetic and does multiple things.
