Add a new config option IPSEC_FILTERGIF to control whether or not
packets coming out of a GIF tunnel are re-processed by ipfw, et. al.
By default they are not reprocessed. With the option they are.
This reverts 1.214. Prior to that change packets were not re-processed.
After they were which caused problems because packets do not have
distinguishing characteristics (like a special network if) that allows
them to be filtered specially.
This is really a stopgap measure designed for immediate MFC so that
4.8 has consistent handling to what was in 4.7.
