netpoll: expose UDP packet builder helpers for netconsole
Promote each from file-static to EXPORT_SYMBOL_GPL and forward-
declare them in include/linux/netpoll.h so netconsole can call
them once netpoll_send_udp() moves out.
These exports are kept until the end of the series, when
al of them move into netconsole.
No functional change.
