If `TextControlState` does not have `TextEditor` and its `SetValue()` is called
from `SetUserInput()`, `TextControlState` itself needs to dispatch `beforeinput`
event.
If the value is modified by `beforeinput` event listener, it's intended that
`preventDefault()` is called by the web apps. However, the behavior in this
case is not mentioned by UI Events nor Input Events spec. We should just file
a spec issue instead of emulating Chrome's behavior for now because it requires
more changes, but this case must be an edge case.

This patch adds a lot of `beforeinput` event tests into existing mochitests
which test `input` events. But this does not add tests of canceling
`beforeinput` event because it requires really complicated path until
implementing `beforeinput` actually.
Note that `beforeinput` event is not fired with `Document.execCommand()`.
Therefore, this patch does not add WPT for testing `beforeinput` event.
And unfortunately, WPT cannot test most cases of the new tests.

`AutoEditActionDataSetter` is created in the stack when editor's public method
is called and that guarantees lifetime of global objects in editor such as
editor itself, selection controller, etc.
The dispatcher of `beforeinput` event returns `NS_ERROR_EDITOR_ACTION_CANCELED`
if an event is actually dispatched but canceled. The reason why it's an error
is, editor code must stop handling anything when any methods return error.
So, returning an error code is reasonable in editor module. But when it's
filtered by `EditorBase::ToGenericNSResult()` at return statement of public
methods, it's converted to `NS_SUCCESS_DOM_NO_OPERATION`. This avoids throwing
new exception, but editor class users in C++ can distinguish whether each edit
action is canceled or handled. The reason why we should not throw new
exception from XPCOM API is, without taking care of each caller may break some
our UI (especially for avoiding to break comm-central). Therefore, this patch
does not make XPCOM methods return error code when `beforeinput` event is
canceled.
In most cases, immediately after creating `AutoEditActionDataSetter` is good
timing to dispatch `beforeinput` event since editor has not touched the DOM
yet. If `beforeinput` requires `data` or `dataTransfer`, methods need to
dispatch `beforeinput` event after that. Alhtough this is not a good thing
from point of view of consistency of the code. However, I have no better
idea.
Note 1: Our implementation does NOT conform to the spec about event order
between `keypress` and `beforeinput` (dispatching `beforeinput` event after
`keypress` event). However, we follow all other browsers' behavior so that it
must be safe and the spec should be updated for backward compatibility.
Spec issue: https://github.com/w3c/uievents/issues/220
Note 2: Our implementation does NOT conform to the spec about event order
between `compositionupdate` and `beforeinput`. Our behavior is same as
Safari, but different from Chrome. This might cause web-compat issues.
However, our behavior does make sense from point of view of consistency of
event spec. Additionally, at both `compositionupdate` and `beforeinput`,
composition string in editor has not been modified yet. Therefore, this
may not cause web-compat issues (and I hope so).

Note that this patch makes editor detect bugs that `beforeinput` event hasn't
been handled yet when it dispatches `input` event or modifying `data` and
`dataTransfer` value are modified after dispatching `beforeinput` event with
`MOZ_ASSERT`s.

SpecialPowers.spawn bounces tasks off SpecialPowersParent before sending them
to SpecialPowersChild, which means that any operations which are sent
immediately afterwards and take a more direct route (like zoom changes) will
get to the content process before the task starts running. In the case of
tasks which depending on registering a listener before said operations take
place, this is obviously a problem.
So this patch fixes those cases in this test to wait for the listeners to be
setup before continuing.

There was a race between the add-on adding its pref listener and us flipping the enabled pref. By waiting for
the balrog migration, we give the add-on time to start listening for the pref before setting it.

We don't want to run stream conversion in the parent (since a lot of them require access to the document), so this instead adds a way to find out what their output type will be.

This is generally pretty straightforward, and rewrites nearly all calls. It
skips the ones that it can detect using frame script globals like
`sendAsyncMessage`, though.

Some of these were obvious typos. Others probably reflect once-correct components
that have been combined, split, or otherwise obsoleted; for these I've tried to
use the component associated with the bugs for recent changes to the affected files.
