Zhe Weng 194d0cdec9 net/procfs: Simplify logic for tcp/udp stats
By:
1. Take out net_ip_binding_laddr/raddr macro
2. INET6_ADDRSTRLEN is long enough for all address buffer and no need to
   add 0 to the end of buffer since inet_ntop will do so

Zhe Weng 075eb6a6d2 net/udp: Change conn->readahead to I/O buffer chain
When using IOB queue to store readahead data, we use one IOB for each
UDP packet. Then if the packets are very small, like 10Bytes per packet,
we'll use ~1600 IOBs just for 16KB recv buffer size, which is wasteful
and dangerous. So change conn->readahead to a single IOB chain like TCP.

Benefits:
- Using memory and IOBs more efficiently (small packets are common in
  UDP)

Side effects:
- UDP recv buffer size may count the overhead
- A little bit drop in performance (<1%, more seek & copy)
