As Chrome and Safari didn't block autoplay when haiving user input on editable content, it causes a compatible issue on Firefox because we only allow user inputs happening on non-editable content to activate document.
It seems that we don't really need to restrict that user inputs, which can activate document, should only occur on non-editable content.
Even if they occur on non-editable content, it might still have a chance to annoy user, it's totally depending on websites' design.

When contents notify IME or requests something to IME, they need to use
an `nsIWidget` instance which may have focus if active, and handles
native keyboard/IME events since that knows correct native IME context.
Currently, such widget exactly matches with the result of
`nsPresContext::GetRootWidget()`. However, this is unclear for most developers.
Therefore, this patch creates a wrapper method of it named
`nsPresContext::GetTextInputHandlingWidget()`. Then, also adds
`BrowserParent::GetTextInputHandlingWidget()` wraps it. Finally, makes
`IMEStateManager` call `GetTextInputHandlingWidget()` of them.

We check surrogate pair at specific index in `nsTextFragement` in a lot of
places. This requires boundary check of the index so that it can cause
security issue and crash reason with simple mistake, and also it steals
your time to understand the code what it does especially when it's a
part of an `if` condition.
Therefore, this patch adds new API to `nsTextFragment` and makes the all
surrogate pair handlers of `nsTextFragument` use new API.

`IMEContentObserver` treats `<br>` elements as linefeed, but ignores padding
`<br>` elements. Padding `<br>` element for last empty line was inserted as
normal `<br>` element and then, its attribute was set by editor. Therefore,
`IMEContentObserver` needed to observe attribute changes. However, editor
stops using attribute to mark as padding and stops inserting as normal `<br>`
element first (i.e., inserting `<br>` after setting its flag). Therefore,
`IMEContentObserver` does not need to observe attribute changes anymore.

Editor creates a `<br>` element to end of a block if last line
of the block is empty because caret should be placed as there is an empty
line. Such special `<br>` element has `type` attribute whose value is "_moz".
However, adding/removing the attribute is expensive and such hacky attribute
shouldn't be referred nor changed by web apps.
Therefore, this patch makes `HTMLBRElement` take another specific flag whether
it's a special node for empty last line. For making the meaning clearer,
this patch calls the such `<br>` elements as "padding `<br>` element for
empty last line" insead of "moz-br". So, this patch also includes a lot of
renaming methods and variables, and modifying related comments.
Note that with this change, `IMEContentObserver` counts the padding `<br>`
element in `<textarea>` because it's inserted before setting the new flag
and setting the flag does not cause DOM tree mutation. This issue will be
fixed by the following patches.

Editor creates a `<br>` element when it's root element is empty.
Then, it's stored by `TextEditRules::mBogusNode` and used for checking
whether the editor is empty quickly. However, this `<br>` element has
`mozeditorbogusnode` attribute whose value is `true`. However, adding or
removing the attribute is not cheap and web apps can refer such illegal
attribute.
Therefore, this patch makes `HTMLBRElement` take a specific flag whether
it's a bogus node or not. However, this means that this hacky thing will be
exposed outside editor module. For making what is the bogus node clearer,
this patch calls the such `<br>` elements as "padding `<br>` element for
empty editor". So, this patch also includes a lot of renaming methods and
variables, and modifying related comments.

This was an oversight in bug 1520154. We kept the -moz- version in the specified
value but not the computed value.
That's a very peculiar way of making aliases work. This makes them work
consistently as many other aliases instead.
Also, add an assert that would've caught this much much earlier.

If copying selected password is allowed by `TextEditor`, we should allow to
drag it too because web apps usually request to input new password twice,

First, we need to make `nsCopySupport::FireClipboardEvent()` keep handling
`eCopy` and `eCut` event even in password field, only if `TextEditor` allows
them.
Then, we need to make `nsPlainTextSerializer::AppendText()` not expose
masked password for making users safer. Although `TextEditor` does not allow
`eCopy` nor `eCut` when selection is not in unmasked range. Fortunately,
retrieving masked and unmasked password from `nsTextFragment` has already
been implemented in `ContentEventHandler.cpp`. This patch moves it into
`EditorUtils` and makes `ContentEventHandler.cpp` and `nsPlaintextSerializer`
share it.

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

This is what other browsers do, and it does make sense to me, it's useless to
try to scroll a frame with no scroll range in a given direction.
I think all callers of this function should be treated like this, so this is
more like a RFC / feedback request than a patch per se.
The wheel handling code already checks scroll range, so there's no difference of
behavior in that case, if I'm reading the code right.
There are a few other functions that check the result of
GetPerceivedScrollingDirections(), but I think if we change this we should
change this consistently.
I also think that if we do this we should rename the method to something like
GetAvailableScrollingDirections() or such.
Anyhow, wdyt? I should also add a test for this if we go with this.

Unmasking is an optional style of showing password. Therefore, if callers of
`nsIEditor::Unmask()` specify middle of surrogate pair(s), it may mean that
they want to expand the unmask range from shorter range which does not include
the high and/or low surrogate. Therefore, one of the surrogates is in unmasked
range, we unmask the surrogate pair. However, we handle this in a lot of
places, i..e., we have duplicated code. This can get rid of these duplicates
with making `nsIEditor::Unmask()` expand the range automatically.

Now, the anonymous text node has raw value of password so that we shouldn't
allow users to drag the text since another user may have typed the password
and left from the device.
Note that we've supported the operation, however, it does not make sense
since the dragging data is masked text.
Additionally, Chrome also doesn't support dragging text in password fields.
So, we have no reason to support dragging raw value from password fields.

My preference was to annotate most of the failing tests with `fail-if` so that
if they start passing, the `fail-if` needs to be removed and they need to keep
passing. That doesn't work for tests that timeout, or which trigger failures
from their cleanup functions, however, so those tests need skip-if. And tests
with fail in their cleanup functions likely leave the browser in an
inconsistent state for subsequent tests, anyway, so really should be skipped
regardless.
There are some remaining tests which still fail because of crashes. I chose
not to skip them here, but to fix the crashes in separate bugs instead.
