Currently some TCP socket option information is stored in SkOptsEntry,
which is a little confusing.
SkOptsEntry should only contain socket options that are common to
all sockets.
In this commit move the TCP-specific socket options from SkOptsEntry
to TcpOptsEntry.

Currently some of the TCP socket option information is stored in the
TcpStreamEntry, but the information in the TcpStreamEntry is only
restored after the TCP socket has established connection, which
results in these TCP socket options not being restored for
unconnected TCP sockets.
In this commit move the TCP socket options from TcpStreamEntry to
TcpOptsEntry and add dump_tcp_opts() and restore_tcp_opts() for TCP
socket options dump and restore.

We found that sometimes a restored tcp socket doesn't work.
A reason of this bug is incorrect window parameters and in this case
tcp_acceptable_seq() returns tcp_wnd_end(tp) instead of tp->snd_nxt. The
other side drops packets with this seq, because seq is less than
tp->rcv_nxt ( tcp_sequence() ).
We need to restore window parameters to avoid such side effects.

But keep @protobuf as a symlink: we have
