Revert previous patch generated by badnull.cocci script, and apply the new one.
The main difference is that assert and assert-like functions are not touched
anymore.

Apply badzero.cocci, badnull.coci and badnull2.cocci
This should convert all cases where there's a comparison to NULL to simpler
forms. This patch applies the following transformations:
code before patch ||code after patch
===============================================================
return a == NULL; return !a;
return a != NULL; return !!a;
func(a == NULL); func(!a);
func(a != NULL); func(!!a);
b = a == NULL; b = !a;
b = a != NULL; b = !!a;
b = a == NULL ? c : d; b = !a ? c : d;
b = a != NULL ? c : d; b = a ? c : d;
other cases:
a == NULL !a
a != NULL a

Since badzero.cocci depends on coccinelle knowledge about a variable being a pointer
and about a function returning a pointer, maybe there are false negatives.
