Fix strncmp to not blindly read past string end #164
Currently strcmp calls strncmp with usize::MAX which causes a panic due to the use of from_raw_parts.
thread 'main' panicked at library/core/src/panicking.rs:155:5:
unsafe precondition(s) violated: slice::from_raw_parts requires the pointer to be aligned and non-null, and the total size of the slice not to exceed `isize::MAX`
This issue is triggered, for instance, when trying to create a keyboard widget.
This PR changes the implementation of strncmp to iterate over the strings up to the specified size but stopping on null bytes.
