a50ccbd240 avutil/tests/lfg.c: added proper normality test 
The Chen-Shapiro(CS) test was used to test normality for
Lagged Fibonacci PRNG.

Normality Hypothesis Test:

The null hypothesis formally tests if the population
the sample represents is normally-distributed. For
CS, when the normality hypothesis is True, the
distribution of QH will have a mean close to 1.

Information on CS can be found here:

This reverts commit faa9d29829.

This change became superfluous when support for C11 atomics was introduced.
Reverting it will make the removal of this implementation in an upcoming
merge conflict free.

554bc4eea8 avcodec, avutil, avformat: remove AVOption requirement for some fields 
Allow all struct fields to be accessed directly, as long as they're
public.

Before this change, many fields were "public", but could be accessed via
AVOption only. This meant they were effectively not public, but were
present for documentation purposes, which was incredibly confusing at
best.
