This is necessary in order to parse style attributes using the subject
principal of the caller, rather than defaulting to the page principal.

In order to tailor certain security checks to the caller that is attempting to
load a particular piece of content, we need to be able to attach an
appropriate triggering principal to the corresponding requests. Since most
HTML content is loaded based on attribute values, that means capturing the
subject principal of the caller who sets those attributes, which means making
it available to AfterSetAttr hooks.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

The main purpose of defining this is to make conversion of places that
use the non-CC variant easier. There are many more places that could
be converted to use these new macros, if somebody felt motivated.

In order to speed up IsDisabled(), instead of querying for the @disabled
attribute, we're now using the NS_EVENT_STATE_DISABLED flag to know whether an
element is disabled.
It is safe to use the NS_EVENT_STATE_DISABLED flag for the following reasons:
- For form elements, nsGenericHTMLFormElement::IsDisabled() is only called on
form elements that can be disabled; form elements that can't be disabled
overrides IsDisabled() to return false directly.
And, before this patch, NS_EVENT_STATE_DISABLED flag is set by
nsGenericHTMLFormElement::IntrinsicState() if and only if IsDisabled() in all
cases when CanBeDisabled() is true, and when CanBeDisabled() is false then
IsDisabled() is always false and the flag is not set.
- For non form elements, optgroup and option have the flag matching
IsDisabled(). Note that option's IsDisabled() should also refer to optgroup's
(if it exists) disabled state, which was not done before this patch.
For this to work correctly, we need to set NS_EVENT_STATE_DISABLED earlier,
that is, in AfterSetAttr(), before any consumer of IsDisabled().
We also need to update the flag whenever the element's parent (e.g. fieldset or
optgroup) disabled state changes and when moving into/out of a parent
container.
Note that NS_EVENT_STATE_DISABLED/ENABLED is now part of the
EXTERNALLY_MANAGED_STATES.

In order to facilitate the movement of code with side-effects called by Element::SetAttr to Element::BeforeSetAttr and Element::AfterSetAttr, Element::AfterSetAttr should have access to the old value of the attribute. This includes information about whether there was previously a value set or not.
Accomplishing this involved passing an additional argument through functions that find and change the old attribute value in order to ensure that we can differentiate between an empty old value and an absent old value (attribute was not set).
Note that while I tried to ensure that accurate values (and their absence) are reported to Element::AfterSetAttr, I largely ignored SVG. While the old value reported for SVG values should be however accurate the value already being reported to SetAttrAndNotify was, SVG elements do not currently report unset values properly because they will never pass a null pointer to SetAttrAndNotify.

This removes the requirement that BeforeSetAttr comes before AttributeWillChange
(which needs the preparsed new value).

With this patch, the disabled state is still kept in the nsPresState,
but we will only honor that if the state saved asks as to re-enable the
control.
The behavior is changed so that controls disabled by JavaScript will be
kept enabled as the JavaScript world gets reloaded.

Enable nsAttrValue::EnumTable to be initialized with enum. So, we could get rid
of the castings in EnumTable. Fix EnumTable initialization comment.
For those untyped enumerations, declare them with uint8_t, as to other typed
enumerations with type size larger than int16_t, force casting to int16_t.
Use {nullptr,0} instead of {0} to represent the last entry.

The user can switch to the main <summary> by tab key, and toggle the
<details> by either 'space' key or 'enter' key.
'return' key is handled with 'keypress', and the 'space' key is handled
with 'keyup' like the HTMLInputElement.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
