Replace strncpy with strlcpy

[philipphofmann]

Description

Our codebase uses strncpy, which is unsafe according to the Apple Secure Coding Guide. We should replace it with strlcpy. Worth investigating if KSCrash has already fixed this.

If we can simply replace strncpy with strlcpy, cause the code has test coverage we should do this quickly. If replacing is a bit complicated, needs refactoring to make things testable, we should reconsider the priority.

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!
