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. Closes: <https://github.com/shadow-maint/shadow/issues/1120> Link: <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=117059> Link: <https://software.codidact.com/posts/292718/292759#answer-292759> Signed-off-by: Alejandro Colomar <alx@kernel.org>
