Here you remove index >= (*array).len() check.

get_ptr() does this check. It is safe, actually.

Panicing on a null pointer changes the behaviour of the ffi, i think we should avoid this. If it's null, we should return a 0

@r10s what do you think about this? Is it likely that we break android/ios at some points with this change?
<Jikstra> we have to be careful with panics in the ffi just because array is a null pointer
<Jikstra> the api allowed us to do weird stuff, panicing will break all apps based on -core-rust
<link2xt[m]> yes, but such panics can be easily debugged
<link2xt[m]> if FFI call panics, it panics immediately
<link2xt[m]> and then you know you should not pass invalid value into it
<link2xt[m]> a simple if is enough to fix it in this case, but it may happen to be an actual bug
