Remove superfluous casts
- Every non-const pointer converts automatically to void *. - Every pointer converts automatically to void *. - void * converts to any other pointer. - const void * converts to any other const pointer. - Integer variables convert to each other. I changed the declaration of a few variables in order to allow removing a cast. However, I didn't attempt to edit casts inside comparisons, since they are very delicate. I also kept casts in variadic functions, since they are necessary, and in allocation functions, because I have other plans for them. I also changed a few casts to int that are better as ptrdiff_t. This change has triggered some warnings about const correctness issues, which have also been fixed in this patch (see for example src/login.c). Signed-off-by: Alejandro Colomar <alx@kernel.org>
