Detailed Description

(function, data, user, datanotify, usernotify) tuples used by the callback-flavoured lists and queues to store deferred work without losing track of ownership.

Two variants are provided: RFuncCallbackCtx for callbacks returning void and RFuncReturnCallbackCtx for callbacks returning rboolean. The r_func_callback_ctx_* / r_func_return_callback_ctx_* inline accessors initialise the tuple, invoke its destroy notifiers, and call the wrapped function with the correct argument order.
