nsContentUtils::ExtractErrorValues converts `aSourceSpecOut` from
UTF-16 to UTF-8, which is generally not what we want. This patch
introduces a new version of ExtractErrorValues that doesn't perform
the conversion. To keep the patch short and avoid rewriting existing
clients, the existing version of the function is left in place.

Early in the startup the channel creation might fail,
in nsStringBundle load and any further attempts are prevented which
leads to broken ocaization support for the process. Let's wait until
the child process learns about the chrome URLs registered on the parent
side with the preloads.
This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

In order to let necko postpone the load of favicon, we have to set request context ID to the http channel that is created to load favicon.
This patch starts with passing a request context ID to nsContentUtils::LoadImage and makes other necessary changes to set the request context ID to the channel.
It a stateless wrapper around static methods in nsHTMLTags and nsHTMLElement,
and hence an unnecessary layer of indirection that just adds complexity and

nsHTMLElement methods.

We call attributeChangedCallback in two cases:
1. When any of the attributes in the observed attribute list has changed,
appended, removed, or replaced.
2. When upgrading an element, for each attribute in element's attribute list
that is in the observed attribute list.

Bug 1334051 - Part 3: Optimize attributeChanged callbacks. r=smaug
The failure mode in the attached crashtest is an inconsistency in the flattened
tree. Specifically, we null out mVideoControls in an nsVideoFrame, but defer
the UnbindFromTree call on that NAC element, which measn that its mParent still
points to the nsVideoFrame's mContent. Because all this stuff runs off of script
runners, and the anonymous content destroyer is not guaranteed to run before
other potential script runners, we end up running arbitrary script while the
tree mismatch exists. This script calls back into ProcessPendingRestyles, which
causes trouble.
We could build a separate deferral mechanism, but it's not clear that we actually
need to defer the unbind anymore. The deferred unbind was added in bug 489008,
which predated a lot of simplifications in layout/dom interaction.

This patch makes the media statistics report values with a fixed frames per second
and a dynamic dropped ratio when resistance fingerprinting is enabled. The dropped
rate is decided by the video resolution that it will report a fixed dropped rate
when the video resolution is greater than 480p. And It will report a zero dropped
rate if the video is below or equal to 480p. In addition, it adds three new prefs
that allow us to change the value of frames per second, the dropped ratio and the
threshold of target video resolution. The three prefs are
'privacy.resistFingerprinting.video_frames_per_sec', 'privacy.resistFingerprinting.video_dropped_ratio'
and 'privacy.resistFingerprinting.target_video_res'. The default values of them
are 30, 5 and 480, which means 30 frames per second, 5 percent dropped ratio and
480p.
This also adds a new helper function 'nsContentUtils::ShouldResistFingerprinting(nsIDocument* aDoc)'
for checking whether fingerprinting resistance is enabled for a given docuemnt.
If it is a chrome document, this function will indicate that fingerprinting
resistance is not enabled regardless of the pref 'privacy.resistFingerprinting'.
If it is a content document, the result will depend on the pref.

The list returned by getElementsByName is cached, however, it's rebuilt
frequently due to content mutations. We can avoid rebuilding the list when
the attribute changed is not the name attribute. We can also speed up the
name matching process by skipping the elements that do not have a name
attribute.

DOM Standard defines that offset of Range is unsigned long. However, nsRange uses int32_t to them.
This patch makes nsRange use uint32_t instead. However, this patch does NOT allow to set over INT32_MAX as offset values since a lot of users of nsRange cannot treat the values as over INT32_MAX because a lot of internal APIs take int32_t as offsets.
For easier to search such points, this patch adds static_cast<int32_t> to uint32_t variables when they are used for int32_t arguments.
And note that nsContentUtils::ComparePoints() behaves odd. It accepts negative offset and compares such value with valid offset simply. This patch still uses int32_t offset variables in nsRange::CompareNodeToRange() even though it may be negative value if nsINode::IndexOf() returns -1 because the caller of it depends on this behavior.

This patch adds a new service for fingerprinting resistance, which is called
nsRFPService. This service will be put in /toolkit/components/resistfingerprinting.
This service is responsible for observing the change of pref 'privacy.resistfingerprinting'
and doing underlying jobs. And it also in charge of caching pref setting of
'privacy.resistfingerprinting' and changing environment value 'TZ'.
This service will be initialized within nsContentUtils::Init(). During initialization,
it will store the original TZ value and set the value according to 'privacy.resistfingerprinting'.
It also changes environment value 'TZ' and calls nsJSUtils::ResetTimeZone() in
response to the change of the pref.
This service is only a nsIObserver for now. In the future, however, it will be
responsible for more fingerprinting resistance jobs, like changing prefs after
'privacy.resistfingerprinting' is changed.
The environment variable 'TZ' will be set to 'UTC' when 'privacy.resistFingerprinting'
is true. By doing so, Firefox will use UTC as its local time zone instead of the
default local time zone. This prevents a browser be fingerprinted through the local time zone.
After the 'privacy.resistFingerprinting' is turned off, the service will restore
'TZ' back to the original TZ setting, the user's setting or the default system timezone.
