We enable compilation of FOG/Glean on _all_ platforms.
We disable Glean initialization and metric recording on Android (GeckoView) by respecting MOZ_GLEAN_ANDROID.
This way GeckoView just works, consumers don't need to think about it (except in tests, these need to be disabled for Android builds).
Stubbing out the metric implementations will happen in the commits after
this one.

Non-SHIP bfcache seems to be rather complicated here, since it needs to explicitly store inner windows and what not.
SHIP should be able to handle this in a simpler way.
It is possible that some ordering needs still tweaking.

This makes the naming more consistent with other functions called
Insert and/or Update. Also, it removes the ambiguity whether
Put expects that an entry already exists or not, in particular because
it differed from nsTHashtable::PutEntry in that regard.

When binding delegates blur() to BrowsingContext::Blur, the remote side skips
the check given that there is no js on the stack, but we should not skip the
check. This only affects design-mode which allows the focus moving to the root

I'm not sure which category is more appropriate. However, with the current
marker chart layout, DOM markers are displayed further up than JS markers,
so this change makes them more easily visible in the marker chart.

This lifts a bunch of string conversions higher up the stack, but allows
us to make the servo code use utf-8 unconditionally, and seemed faster
in my benchmarking (see comment 0).
It should also make a bunch of attribute setters faster too (like
setting .cssText), now that we use UTF8String for them (we couldn't
because we couldn't specify different string types for the getter and
setters).

Rework the MediaKeys class to shutdown when its parent inner window is destroyed
rather than the document it's created in. This is done to mitigate the case
where a MediaKeys is created in an about:blank document that has not yet
undergone its async load (i.e. blank document that will stay blank, blank
documents loading to other pages will still clobber their keys on load). This
specifically addresses cases where sites could create an iframe, not wait for
load, create a MediaKeys in the iframe, and then find the keys had become
unusable.
This is achieved by associating MediaKeys instances with their inner window and
having the window notify keys when a window is going to be destroyed. I decided
to use this approach rather than have MediaKeys observe for window destruction
for a few reasons:
- The keys would need to support weak references to use the observer service in
the desired way. Implementing this interface on the MediaKeys adds a
non-trivial level of complexity and means the keys would implement the WeakPtr
interface (already in place prior to this patch) and also the NS weak
reference interface, which I found confusing.
- If the inner window stores pointers to MediaKeys created in it, it can be self
aware of if EME activity is taking place within it. The allows us to better
identify EME activity in documents. Historically one of the ways we'd
determined EME activity by checking if media elements have MediaKeys attached,
but this had lead to issues where if MediaKeys are created but not attached
to a media element we overlook them. With this patch's changes, we can also
have a document check its inner window to see if there are any MediaKeys. This
patch uses this to extend our check to avoid bfcaching pages with EME content.
- There appears to be prior art using a similar approach for audio contexts and
peer connections, which I assume is sensible and I'm not reinventing the wheel
by following.

Only for top windows because for nested iframes they could get around
this without being noticed by reloading themselves which is not great.

Currently, the gamepad code uses a uint32_t as a handle and does some trickery
with it by trying to create a unique ID and adding an offset to it for VR code.
This can (and has) led to errors where the developer forgets to perform the
arithmetic and sends the wrong number to the wrong manager.
This change created a strongly-typed handle that remembers which service it
belongs to. This should eliminate such accidents.

On Nightly, for now. This allows websites to get the real viewport size.
The rounded size has caused problems in the past (see bug 1648298 / bug
1648265), and changing it would be ideal.
I told the CSSWG that we can experiment with this on Nightly to
alleviate (or prove) compat concerns, in which case we'd need to use a
different solution, see https://github.com/w3c/csswg-drafts/issues/5260.

This is only the basic outline.
It doesn't do anything yet, but compile.
As there are no metrics generated for it it can't look up anything.
To note: Actual metric types are implemented in XPIDL later.
The following (priviliged) JavaScript code will soon work (if the
corresponding metrics would be defined):
const { Glean } = ChromeUtils.import("resource://gre/modules/Glean.jsm");
Glean.shared.test_only.count_things.add(1);

This changes the way we deal with page use counters so that we can
handle out of process iframes.
Currently, when a parent document is being destroyed, we poke into all
of the sub-documents to merge their use counters into the parent's page
use counters, which we then report via Telemetry. With Fission enabled,
the sub-documents may be out of process. We can't simply turn these
into async IPC calls, since the parent document will be destroyed
shortly, as might the content processes holding the sub-documents.
So instead, each document during its initialization identifies which
ancestor document it will contribute its page use counters to, and
stores its WindowContext id to identify that ancestor. A message is
sent to the parent process to notify it that page use counter data will
be sent at some later point. That later point is when the document
loses its window. It doesn't matter if the ancestor document has
already been destroyed at this point, since all we need is its
WindowContext id to uniquely identify it. Once the parent process has
received all of the use counters it expects to accumulate to a given
WindowContext Id, it reports them via Telemetry.
Reporting of document use counters remains unchanged and is done by each
document in their content process.
While we're here, we also:
* Limit use counters to be reported for a pre-defined set of document
URL schemes, rather than be based on the document principal.
* Add proper MOZ_LOG logging for use counters instead of printfs.

There is similar API in `Document`, but they indicate whether a node has been
observed by any mutation receiver, not only by `MutationObserver` of JS.
However, I'd like to know the percentage of web apps which use
`MutationObserver`, but not use `beforeinput` events. Therefore, this patch
adds similar API into `nsPIDOMWindowInner` as same as `beforeinput` and
ignores `MutationObserver`s which are created by chrome script and addons.
