Keeping a list of ancestor principals in a LoadInfo object, that, at times,
exists in the content process, is not secure. Since ancestor principals are
only ever needed to create a list of frameAncestors, which, in turn, are only
ever accessed from the parent process, we can assemble lists of ancestor
principals and outer windowIDs whenever we are in the parent process and are
either 1) creating a LoadInfo object or 2) deserializing a LoadInfoArgs struct,
received from content process, into a LoadInfo object.

The reply argument that gets passed in is a stack reference which is move
assigned into, so it doesn't make sense as a unique pointer, although the
code could be restructured to return a freshly allocated object instead.
This mostly just eliminates a spurious round trip from UniquePtr to *
and back. The bulk of the patch is renaming uses of |msg| to |aMsg|.

Gcc and Clang dumps gcda files just before an exec** or fork functions.
With ccov enabled, we can dump using a SIGUSR1 but if we're in the middle of dump (because of exec** or fork)
then a gcda file can stay locked and then another process can try to get a lock on it for ever.
So to avoid such a situation, we remove the SIGUSR1 handler just before the fork an set it back just after.

This is more standard, and uses about 4kb less memory when almost empty,
which seems to be the common case in an idle content process. This should save
around 66kb per content process.
The next patch will get ride of this thin wrapper and use nsDataHashtable
directly.

This method is the same as Put(), except that it asserts that the item
is not already present. It also puts the key second. Make it compatible
by hoisting out the assert and reversing the arguments. We can use the
definition of Put() defined in an earlier patch.

nsTHashtable::Remove doesn't assert if the item isn't present. Match that
behavior by removing the assert and putting it at all of the call sites.
This just turns IDMap::Remove into RemoveIfPresent, so merge them.

This function is similar to the Put() method in nsTHashtable, but it lists the
key second and it asserts that the key is not already in the map. This patch
swaps the arguments and hoists the assertion out, where appropriate. Note that
there are a few places that were working around this assert, so for those places
don't include the assert.

GetConstructedEventTarget and GetSpecificMessageEventTarget always return
null. The idea was that subclasses could override them, but nobody does any
more.

We are seeing crashes on aarch64 Fenix devices that appear to be related
to zero-sized messages. But we're seeing the crashes when we're trying
to send the messages on the IO thread, and not where we're dispatching
them from. Add some asserts so we get errors closer to the source, and
add some asserts for other things that we believe to be true and would
be useful to know aren't actually true.

I don't think all this complexity is worth it for having a
marginally-more-realistic testing story. Using the pref just works and we should
do that, I think.

This method always copies, and is redundant with the other getter methods on
IPDL unions. As there is only one caller, it can be removed to simplify the
code, and remove a source of complexity.

Currently, the worker's COEP is saved in WorkerPrivate and not be respected when loading resources in workers.
This patch adds an attribute loadingEmbedderPolicy in nsILoadInfo, which indicates the COEP header the loading must be respected.
The default value of loadingEmbedderPolicy is nsILoadInfo::EMBEDDER_POLICY_NULL.
loadingEmbedderPolicy is initialized with the COEP of the BrowsingContext used for creating LoadInfo.
And it could be set to other value when fetch in workers.

In this bug we're moving away from monolithic JNI headers to class-specific
headers so that we don't have to rebuild the world every time we make a change
to a JNI interface.
