I don't see that in the github repo, but moving from 17->24 is
straightforward once you get the C++ compile/link conversions
straightend out. The one gocha, which i'm guessing is biting you, is any
calls to JS_NewCompartmentAndGlobalObject() need to be converted to
JS_NewGlobalObject() then you need to construct an JSAutoCompartment and
track it for the lifetime of the GlobalObject (or go ahead and try to
use RAII, but that likely requires higher level restructing of the old C
code). The auto compartment stuff caused me some grief when I initially
ported polkit.
