Log Message:
inpcb: integrate data structures of PCB into one

Data structures of network protocol control blocks (PCBs), i.e.,
struct inpcb, in6pcb and inpcb_hdr, are not organized well.  Users of
the data structures have to handle them separately and thus the code
is cluttered and duplicated.

The commit integrates the data structures into one, struct inpcb.  As a
result, users of PCBs only have to handle just one data structure, so
the code becomes simple.

One drawback is that the data size of PCB for IPv4 increases by 40 bytes
(from 248 bytes to 288 bytes).
