	src/sys/net: if_gre.c if_gre.h
	src/sys/netinet: ip_gre.c

Log Message:
If we do not recognize the protocol of a received packet, then
increase ifi_noproto.  If the GRE header contains routing options,
increase the input-error count, ifi_ierrors.

While I am here, make some cosmetic changes: remove unnecessary
'proto' argument from gre_input3().  Shorten some staircases.
