  Extract buffers management code from tcp.c and

 it to tcp_buf.c
 tcp.c keeps all the generic code and will be also used by
 the vhost-user functions.
 
 Also compare mode to MODE_PASTA, as we will manage vhost-user
 mode (MODE_VU) like MODE_PASST.   
 
 Something in this series breaks the pasta_podman/bats test, number 19
 in that script (Single TCP port forwarding, IPv4, tap). I'm bisecting
 now...

    tap: use in->buf_size rather than sizeof(pkt_buf)
    
    buf_size is set to sizeof(pkt_buf) by default. And it seems more correct
    to provide the actual size of the buffer.
    
    Later a buf_size of 0 will allow vhost-user mode to detect
    guest memory buffers.
