There's nothing preventing the flat tree from changing while the document
doesn't have a shell. In that case, we really really don't want to lose track
of elements with stale style data, since then we'll mess up.
It's ok to _not_ clear the style data when the document goes into the BFCache
though, because the document is thrown away if other document runs script and
touches the cached DOM.

The difference between nsDocument::IsWebAnimationsEnabled and
nsContentUtils::AnimationsAPICoreEnabled is that the former checks the caller
type and treats the preference as set for system callers which is particularly
needed for enabling things like the getProperties() API for DevTools etc.
Generally in API-facing call sites we have a JS context / CallerType and so we
want to distinguish between system callers and non-system callers. However, for
a few internal uses--specifically filling-in missing keyframes--we don't care
about the caller type and always follow the pref setting.
That may or not be quite what we want, but this patch doesn't change that except
for one call site: KeyframeUtils::GetKeyframesFromObject. This patch changes
GetKeyframesFromObject from *not* checking the caller type to checking the
caller type. That seems to be the correct behavior here since this is called
from KeyframeEffectReadOnly::SetKeyframes(JSContext*, JS::Handle<JSObject*>,
ErrorResult&) (i.e. a JS API-facing call site) where we *should* enable the full
API when the caller is chrome code.

This flag would be used to help us decide whether website could be allowed the autoplay.
The media related implementation would be implemented in bug1382574.

This is a large patch which tries to switch many of the external consumers of
nsGlobalWindow to instead use the new Inner or Outer variants.

This makes it a bit more straight-forward to change the system font scale,
preserving the sync MediaFeatureChanged event.
This also avoids notifying media queries when the shell is not initialized.
In particular, the patch in bug 1404545 allows calling MediaFeatureValuesChanged
on a still-initializing pres-shell. This is nasty, and all this initialization
order is kind of a mess, but I'm not reworking it for now...
Also, this drops the invalidation of font-inflation when a doctype is added to
the document. GetViewportInfo() already relies on the doctype not changing, as
noted in a comment.

There are several ways that expanded principals can be used as triggering
principals for requests. While that works fine for security checks, it also
sometimes causes them to be inherited, and used as result principals in
contexts where expanded principals aren't allowed.
This patch changes our inheritance behavior so that expanded principals are
downgraded to the most appropriate constituent principal when they would
otherwise be inherited.
The logic for choosing the most appropriate principal is a bit suspect, and
may eventually need to be changed to always select the last whitelist
principal, but I chose it to preserve the current principal downgrade behavior
used by XMLHttpRequest for the time being.

Add a new member mAllowPaymentRequest on nsIDocument and following related
methods,
bool AllowPaymentRequest() const
void SetAllowPaymentRequest(bool aAllowPaymentRequest)
mAllowPaymentRequest is used to check if PaymentRequest is allowed to use on
the document. According to the spec
https://html.spec.whatwg.org/multipage/iframe-embed-object.html#allowed-to-use
the mAllowPaymentRequest should be true under following situations
1. The document is the top level content document.
2. The document is the same origin with its parent document and its parent
document's mAllowPaymentRequest is true.
3. The document is different origin with its parent document but its
parent node is an iframe with allowpaymentrequest flag and the parent
document's mAllowPaymentRquest is true.
This patch also include following mochitests
1. test for allowpaymentrequest flag changing. The flag change effect should
not be applied to the document immediately, it should be updated while
the browsing context is updated.
2. test for effect propagation in the nested iframe.
Per spec, document objects have a throw-on-dynamic-markup-insertion counter,
which is used in conjunction with the create an element for the token algorithm
to prevent custom element constructors from being able to use document.open(),
document.close(), and document.write() when they are invoked by the parser.
Every time a document is destroyed, we record whether MathML was enabled,
which is set to true when a MathML element was bound to the document.
'mathml.doc_count' will report how many such documents existed during a
session. It should be compared to MIXED_CONTENT_PAGE_LOAD, which counts the total number of all page loads.

The current API makes the life time and ownership of the result array unclear
without careful reading. The result array is always owned by the principal,
and its lifetime tied to the lifetime of the principal itself. Returning a
const array reference makes this clear, and should prevent callers from
accidentally modifying the returned array.

There are currently some corner cases where channels that are eventually
loaded into documents (mainly <img src="data:image/svg+xml,") can inherit
expanded principals from a caller. Since documents aren't allowed to have
expanded principals, this causes crashes.
This patch is a short term workaround for the issue, until we have a longer
term solution that prevents the channels from inheriting the expanded
principals to begin with.

In this patch, we read the stylo blocklist into nsLayoutUtils's global static
variable during nsLayoutUtils::Initialize(). So, we can decide if we should
fallback to use Gecko backend while updating style backend for a document.
We add "layout.css.stylo-blocklist.blocked_domains" and
"layout.css.stylo-blocklist.enabled" to ContentPrefs.cpp because they are read
very early (during nsLayoutUtils::Initialize).
