Clean up const usage to avoid excessive casting

Browse Source 
Don't use const on pointers that hold heap allocated data, because that
means functions that free them must cast away the const.

Do use const on pointer parameters or fields that needn't be modified.

Remove pointer casts that are no longer needed after fixing the constness.
