It isn't declared in cni.h.  IMO we shouldn't document or export any
_Jv_ function, only `Jv' functions.

Yes, it does.

I'm not sure this is what you want.  It doesn't make sense to store
the result of _Jv_AllocBytes in a RawData field.  Those fields aren't
scanned, and as _Jv_AllocBytes returns collectible memory, it won't be
considered live.  You probably just want JvMalloc or plain old malloc.
