212683cae4 Bug 965898 - Don't use a FilteringWrapper to get an unfiltered view in ChromeObjectWrapper. r=gabor 
This is necessary because subsequent patches cause us to assert when invoking
getPropertyDescriptor on a FilteringWrapper for which |Policy| denies both GET
and SET.

This stuff is really a mess. I'm looking forward to it going away.

previously had a waiver and decide whether or not to extend it.

65f180179d Bug 1034262 - Honor the wantXrays of both sides of the membrane when computing same-origin wrappers. r=gabor 
The basic problem in the testcase is that one compartment requests same-origin
Xrays via wantXrays=true (the default for Sandboxes) while the other does not.
The current code only considers the wantXrays flag of the compartment performing
the access, so we end up in a situation where we have same-origin compartments,
but Xray in one direction and Transparent in the other.

This is a problem for crossCompartmentFunction.apply(null, [arg]). If both
globals get transparent wrappers, there's obviously no problem. And if both
globals get XrayWrappers, then the |apply| happens on the XrayWrapper of the
function in the caller's compartment. So the Array is unpacked in the caller's
compartment, and again we have no problem.

But if the caller gets Transparent and the callee gets Xrays, then we end up
invoking |apply| from the callee's side, which then gets an XrayWrapper to the
array. This XrayWrapper may do surprising things, leading to the odd situation
in the testcase.

Same-origin Xrays are kind of broken anyway, but I don't think we'll ever be
able to get rid of them. So the most sensible thing to do is probably to honor
the flag (if set) from either compartment. This patch does that.

f99be51d16 Bug 1034239 - Replace GentlyOpaque with an "Xray-to-nothing" wrapper. r=gabor 
I did this wrong before. Making this a SecurityWrapper means that the caller does
not subsumes the target, and that the target therefore needs to be protected
from the caller. But GentlyOpaque was supposed to be an analog of PermissiveXray
for use when no useful XrayTraits exist, so it should behave similarly.

If we make this a Filtering Security Wrapper, we get a bunch of assertions where we
expect CheckedUnwrap to succeed for a chrome-side wrapper. And we can't making it
a Filtering Non-Security Wrapper, because then the filtering policy isn't even
consulted (an optimization in jsproxy.cpp).

Really, we want all of the Xray machinery (like the ability to waive and to place
expandos), and we just don't want to resolve any properties. This patch does this.
