Alejandro Colomar 0b8c0c893c lib/, src/: Use NULL instead of 0 as a null pointer constant ...

GCC 15 will add -Wzero-as-null-pointer-constant for deprecating it,
and I'm working on a paper for deprecating it from ISO C too.
Let's remove any uses in our code base.

I've done this change by building GCC from master, adding
-Werror=zero-as-null-pointer-constant to ./autogen.sh, and fixing every
error that showed up.
