Unused context parameter is used

[harumazzz]

Based on what I have seen from the header file quickjs.h, a lot of function require a JSContext, but does not rely on it. Can I ask what is the purpose of this? Below is an image that demonstrates what I mean.

That;s how the original project defined those APIs... I wouldn't mind dropping it. Thoughts @bnoordhuis ?

I've done that already in piecemeal fashion for other APIs so yeah, feel free to remove them.
