Developers adding global variables.

[Julian Elischer]

If you are adding globals to the networking code, (or if you have 
added soem globals in the last few months, could you make sure that
I am aware of them?

marko Zec and I are trying to keep teh Vimage tree in perforce
in sync with -current but there is noo automatic way that we would
be noticfied of the sudden appearance of a new global variable
in the networking code.

Today I noticed tcp_do_ecn and tcp_ecn_maxretries but only because
of their proximity to another change.

thanks
