Subject: [PATCH] Use repr(transparent) for wrapper structs

`repr(transparent)` provides stronger guarantees that the struct will have the exact same representation as its only field. And `Context` didn't even *have* an explicit representation, not even `repr(C)`!!

Because of all the transmutation that this library does between wrapper types and the types that they wrap, those guarantees are quite important, don't you think? :)
