Move all the TCP parts using internal buffers to tcp_buf.c and keep generic TCP management functions in tcp.c. Add tcp_internal.h to export needed functions from tcp.c and tcp_buf.h from tcp_buf.c With this change we can use existing TCP functions with a different kind of memory storage as for instance the shared memory provided by the guest via vhost-user.
