In order for the SendSideCongestionController to work properly, it needs the
timestamp at which the packets were sent. This is set by calling
Call::OnSentPacket when a packet is sent. Without the sent timestamp, it drops
the estimated available bandwidth so low that only one simulcast stream will
be allocated any bandwidth.

Bug 1624802 - Run some dom/quota xpcshell tests in a child process as well; r=dom-workers-and-storage-reviewers,sg

For now, only test_listOrigins.js, test_originWithCaret.js and test_simpledb.js
can run in a child process because they don't need to set preferences or access
files in the profile directory.
We will be able to run more tests in a child process once we have SpecialPowers
for xpcshell implemented using JSProcessActors and when we expose the base
directory used by QuotaManager through a new QuotaManagerService method (to
avoid getting the profile directory using nsIDirectoryService because that
doesn't work in a child process).

With this patch both events will be emitted when sub frames are
loaded or destroyed.

Because more work is necessary before we can enable general frame
support in Remote Protocol all the code has been put behind the
preference "remote.frames.enabled'. Only if it's true (which is
not the default) the events are emitted.

Bug 1593226 - [remote] Create a single context observer per content session. r=remote-protocol-reviewers,maja_zf

Domains would have created their own instance of the context observer,
which results in duplicated event listeners and observer notifications
to be registered.

This is still not ideal for the observer notifications, which should be
registered only once, but still an improvement for now. Bug 1635568 will
finally fix that.

Per https://html.spec.whatwg.org/#selector-read-write:

> The :read-write pseudo-class must match any element falling into one
> of the following categories [...]:
>
>   * input elements to which the readonly attribute applies, and that
>     are mutable (i.e. that do not have the readonly attribute
>     specified and that are not disabled)
>
>   * textarea elements that do not have a readonly attribute, and
>     that are not disabled.
>
>   * elements that are editing hosts or editable and are neither
>     input elements nor textarea elements.

This fixes the `:disabled` bits.

This matches Safari behavior and the spec, but not Chrome, which has our
behavior.

Fix the WPT, which had multiple issues, as :read-only is defined to be
just the opposite of :read-write. This will pass as soon as I unprefix
the pseudo-class.
