I can't see what this is supposed to be doing. The one caller defaults to aCx,
and if not, gets and pushes a context associated with the document, restoring
it to the default compartment.
So this only changes the behavior when we use the aCx that comes in from above,
in which case it's totally not clear to me why we would want to get the default
global here.
The goal here is to get rid of this crap entirely, and make nsCxPusher always
push. But that's a scary change, so we do it in chunks. This patch, in particular,
should have zero behavioral change. This means preserving some very wrong behavior.
For instance, currently SafeAutoJSContext never pushes a damn thing, because the
safe JSContext doesn't have an associated nsIScriptContext. We preserve this
behavior, and in fact convert various similarly-buggy consumers to
SafeAutoJSContext, so that we can hoist the behavioral change into a subsequent
patch.
Use uint64_t where appropriate for mData, fails to build on OpenBSD
otherwise with wrong casts/no matching template.
