title: Does golang provide htonl/htons?
body: <p>In C programming, when I want to send an integer across network, we need to use htonl() or htons() to convert the integer from host byte order
  to network byte order before sending it.</p>
  
  <p>But in golang, I have checked the net package, and can't find the similar functions like htons/htonl. So how should I send an integer when using golang? Do I need to implement htons/htonl
   myself?</p>
