Because the ip_id code initialisation is a specific case of shuffling a set of incrementing integers (and not an arbitrary set of values) it is possible to populate the array as we shuffle it in a single forward pass. Clever optimisation from didickman AT gmail.com; ok deraadt@ mcbride@

Add a arc4random_uniform() that returns a uniformly distributed number in the range 0 <= x < upper_bound Please use this new API instead of "arc4random() % upper_bound", as it avoids the "modulo bias" that favours small results when upper_bound is not a power of two. feedback deraadt@ mcbride@; ok deraadt@

replacement algorithm. initialize a 64K-short buffer using Durstenfeld shuffle. Upon allocation, swap-permute the new value to a random slot in the 0..32K-1 th entry of the buffer as we move forward, ensuring randomness but also satisfying the non-repeating property we need. Also avoid the value of 0, since IP ID's of 0 are special. Inspired by Dillon's implementation. We believe this is easier to read though, initializes with less bias, handles the ID of 0 properly, and wins speed tests. Thanks a lot to mcbride and djm for doing a bunch of statistical and speed analysis, and comments from nordin ok mcbride djm

First step towards more sane time handling in the kernel -- this changes things such that code that only need a second-resolution uptime or wall time, and used to get that from time.tv_secs or mono_time.tv_secs now get this from separate time_t globals time_second and time_uptime. ok art@ niklas@ nordin@

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)

Merge in -current from two days ago in the SMP branch. As usual with merges, they do not indicate progress, so do not hold your breath for working SMP, and do not mail me and ask about the state of it. It has not changed. There is work ongoing, but very, very slowly. The commit is done in parts as to not lock up the tree in too big chunks at a time.
