Where is "open" in "core.sys.linux.unistd"?

Because file descriptors are created in different ways.

For example, `open` exists for files 
[here](https://github.com/dlang/druntime/blob/master/src/core/sys/posix/fcntl.d)

But opening a socket is done via the `socket` system call 
[here](https://github.com/dlang/druntime/blob/master/src/core/sys/posix/sys/socket.d)

They don't take the same arguments (nor should they).

But reading/writing, closing these file descriptors is always the same.
