'RELENG_5_3_0_RELEASE'. This commit was manufactured to restore the state of the 5.3-RELEASE image.

Use 'uint32_t' instead of 'long' when a 32-bit integer is intended.

This results in no functional change, aside from fixing a data corruption bug on LP64 platforms. The code here could still use a significant amount of cleanup. PR: 56502 Submitted by: hrs (earlier version)

For type 0 rng lower initial drop to 50, it is enough to hide linearity

Reorganize historic #ifdef section

For rand(3) and random(3) TYPE_0 drop NSHUFF values right after srand{om}()

to remove part of seed -> 1st value correlation. Correlation still remains because of algorithm limits. Note that old algorithm have even stronger correlation, especially in the lower bits area, but not eye-visible, as current one.

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.

Fix the style of the SCM ID's.

I believe have made all of libc .c's as consistent as possible.

Remove __P() usage.

Remove 'register' keyword.

Add a long-overdue nail to the deprecated /dev/urandom interface

by asking some things that need unpredictable numbers to read /dev/random instead.
