Michal Privoznik 4f159d4269 lib: Finish using struct zero initializer manually 
There are some cases left after previous commit which were not
picked up by coccinelle. Mostly, becuase the spatch was not
generic enough. We are left with cases like: two variables
declared on one line, a variable declared in #ifdef-s (there are
notoriously difficult for coccinelle), arrays, macro definitions,
etc.

Finish what coccinelle started, by hand.
