Revert r330897:
This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.
Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes.

MFC r327295: Start syncing changes from OpenBSD's ip6_id.c instead of ip_id.c.
correct non-repetitive ID code, based on comments from niels provos. - seed2 is necessary, but use it as "seed2 + x" not "seed2 ^ x". - skipping number is not needed, so disable it for 16bit generator (makes the repetition period to 30000)
Obtained from: OpenBSD (CVS rev. 1.2)

Get rid of the RANDOM_IP_ID option and make it a sysctl. NetBSD have already done this, so I have styled the patch on their work:
1) introduce a ip_newid() static inline function that checks the sysctl and then decides if it should return a sequential or random IP ID.
2) named the sysctl net.inet.ip.random_id
3) IPv6 flow IDs and fragment IDs are now always random. Flow IDs and frag IDs are significantly less common in the IPv6 world (ie. rarely generated per-packet), so there should be smaller performance concerns.
The sysctl defaults to 0 (sequential IP IDs).
