This helper makes it considerably easier for C++ code to import a JS module
and wrap it in an appropriately-defined XPIDL interface for its exports.
Typical usage is something like:
Foo.jsm:
var EXPORTED_SYMBOLS = ["foo"];
function foo(bar) {
return bar.toString();
}
mozIFoo.idl:
interface mozIFoo : nsISupports {
AString foo(double meh);
}
Thing.cpp:
nsCOMPtr<mozIFoo> foo = do_ImportModule(
"resource://meh/Foo.jsm");
MOZ_TRY(foo->Foo(42));

Because it release-asserts the compartment has a single realm.
I also renamed JS_GetCompartmentPrincipals to JS_DeprecatedGetCompartmentPrincipals
to discourage people from using it.

Replace with just unwrapping the key, since there are no users that return anything else for a delegate.

We have a few places where C++ calls ChromeUtils::Import directly.
I fixed these to pass the target object directly instead of an empty Optional<>.

With same-compartment-realms enabled we can call a cross-realm Cu.importGlobalProperties
and we ended up defining properties on the wrong global.

For *incoming* wrappers this preserves behavior. We nuke *outgoing* wrappers
when all realms in the compartment have been nuked. To implement this I moved
the wasNuked flag from XPConnect to JS::Compartment as nukedOutgoingWrappers and
to JS::Realm as nukedIncomingWrappers.
The code to create a dead wrapper in the nuked compartment/realm case was also
moved into the JS engine. I added a shell test for it.

Ensure that "a instanceof b" has Xray semantics, i.e. that when b is a
XrayWrapper, that the wrapped object's getters, `Symbol.hasInstance`
hook and proxy traps are not triggered.
The toolkit/components/mozintl/test/test_mozintlhelper.js test was
updated to explicitly waive Xrays, instead of relying on the previous
behavior where Xrays were automatically waived.

This is a best effort attempt at ensuring that the adverse impact of
reformatting the entire tree over the comments would be minimal. I've used a
combination of strategies including disabling of formatting, some manual
formatting and some changes to formatting to work around some clang-format
limitations.

These macros tend to be handled quite poorly since the clang-format

This is a complete rewrite of the interface while maintaining the same APIs.
Each ID is fully-contained within a single object, does not require a finalizer,
and is cheap to create.
Beyond using reserved slots, this code avoids using custom ClassOps, instead
preferring Symbol.hasInstance and eager constants.
One major change which occurred in this patch was the move from storing a nsCID
to storing the ContractID for JSCID objects. This eliminates the need for the
'refreshCID' method, and hopefully shouldn't have performance implications.
If we discover that there are performance problems there, we can look into
stashing the CID, and re-introduce 'refreshCID', despite its surprising
behaviour.

These two interfaces are effectively never used, so to avoid needing to support
ClassID2JSValue with the new implementation, I remove them entirely.

This mostly consists of changes to the XPCComponents objects to avoid using the
implementation details, and instead use the API defined in part 1.

This lets us get rid of the method 'initalize', which currently needs the
internal representation of JSCID.
This particular method is removed entirely in Part 9, and only exists to keep
intermediate states building & running.

This should be mostly compatible with the original implementation. I tried to
simplify things here to just directly wrap and use JS objects, calling methods
on them. This eliminates the nsXPCConstructor type completely, replacing it with
a JSNative constructor with predefined READONLY | PERMANENT properties.

This is the first part of hiding the implementation of nsIJSID behind the
interface added in Part 1, such that we can substitute that implementation out.
I had to make a couple of changes to fix the errors caused by the new behaviour
in GenerateQI.

The new API tries to be more generic, taking and producing JS::Values. It also
supports creating the more specialized IID and CID types.

This patch introduces 2 new prefs:
- devtools.console.stdout.chrome: if true, console API writes on stdout when
used by chrome code
- devtools.console.stdout.content: console API write on stdout when used by
content code.
