Lower initial drop value to 50, it is enough to hide linearity

Use __FBSDID().

Since we drop NSHUFF values now, set default seed to what it becomes
after srandom(1)

Drop NSHUFF values right after srandom() to remove part of seed -> 1st
value correlation. Correlation still remains because of algorithm limits.

Park & Miller PRNG can be safely initialized with any value but 0 and stuck
at 0 as designed. Its BSD adaptation tries to fight it by mapping 0 to
2147483647 after calculation, but this method not works since 2147483647
seed returns to 0 again on the next interation. Instead of after calculation
mapping, map 0 to another value _before_ calculation, so it never stucks.

$Id$ -> $FreeBSD$

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

add simple srandom() and prototype

<libkern/libkern.h> has moved to <sys/libkern.h> (repository copy).
Since /usr/include/libkern doesn't and shouldn't exist, this is the
least evil way to handle this.

Added $Id$
