It should go int tcp_input.c if any because that's the only file that
always needs it now. If you do not have TCP there will be no
tcp_input and TCPDEBUG will make no sense but there can be a tcp_input
without TCPDEBUG/tcp_debug.

It has been used with the extern in netipx since 1995.

It is exposed to user space so moving it out of the header will break

If you have any other better short term solution to not break anything
I am happy but I could not see one.

As said, I am not happy with the extern either.

Software is harder than hardware  so better get it right the first time.
