Change Details

Refactor `sysctl_sysctl_next_ls()` a bit. Move huge inner loop out of `sysctl_sysctl_next_ls()` into a separate function to simplify it a bit and allow further refactoring.

Refactor `sysctl_sysctl_next_ls()`. * Move huge inner loop out of `sysctl_sysctl_next_ls()` into a separate non-recursive function, returning the next step to be taken. * Update resulting node oid parts only on successful lookup * Make `sysctl_sysctl_next_ls()` return boolean success/failure instead of errno, slightly simplifying logic
