I have no idea what this code is trying to do, leave it be.

qmath(3) test: Replace overcomplicated abomination with arc4random(3)
The horrific GENRAND construction bent over backwards to construct 64-bit
signed integers from the 31-bit output of random(3) for about 20 numbers per
test. Reproducibility wasn't a goal: random(3) was seeded with
srandomdev(3). Speed is not a factor for generating 20 integers with
arc4random(3). Range is not a factor: all uses did not bound the range
beyond that of the full [INT64_MIN, INT64_MAX]. Just use arc4random(3).

Introduce <sys/qmath.h>, a fixed-point math library from Netflix.
This makes it possible to perform mathematical operations
on
fractional values without using floating point. It operates on Q
numbers, which are integer-sized, opaque structures initialized
to hold a chosen number of integer and fractional
bits.
For a general description of the Q number system, see the "Fixed Point
Representation & Fractional Math" whitepaper[1]; for the actual
API see the qmath(3) man page.
This is one of dependencies for the upcoming stats(3) framework[2]
that will be applied to the TCP stack in a later commit.
