in6_v4mapsin6_sockaddr() which allocate the appropriate sockaddr_in* structure and initialize it with the address and port information passed as arguments. Use calls to these new functions to replace code that is replicated multiple times in in_setsockaddr(), in_setpeeraddr(), in6_setsockaddr(), in6_setpeeraddr(), in6_mapped_sockaddr(), and in6_mapped_peeraddr(). Inline COMMON_END in tcp_usr_accept() so that we can call in_sockaddr() with temporary copies of the address and port after the PCB is unlocked. Fix the lock violation in tcp6_usr_accept() (caused by calling MALLOC() inside in6_mapped_peeraddr() while the PCB is locked) by changing the implementation of tcp6_usr_accept() to match tcp_usr_accept().
