Currently, nsGenericHTMLElement::CopyInnerTo uses SetInlineStyleDeclaration to clone CSS attributes. However, if we used SetParsedAttr instead, the declaration block would be addref'ed instead of being cloned.
We need to mark the declaration block as immutable in that situation so that the attribute is copied on write.

Now that the side effects of parsing have been relocated to BeforeSetAttr and AfterSetAttr (Bug 1365092), we can easily switch nsGenericHTMLElement::CopyInnerTo from reparsing attributes to cloning them. They are still reparsed, however, in the case where the owning document is changing since Base URIs may have changed.

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 patch does these things:
1. it moves nsScriptElement, nsScriptLoader, ScriptSettings, nsIScriptElement
and nsIScriptLoaderObserver in dom/script
2. it renames nsScriptElement to mozilla::dom::ScriptElement
3. it renames nsScriptLaoder to mozilla::dom::ScriptLoader

The container of a radio group is the form, if it belongs to a form, or the
document object otherwise.
When moving a radio out of a form, we should add it back to a radio group.
Similary, before moving the radio to a form, we should remove it from the
original radio group.

Currently, attribute and child arrays (implemented in dom/base/nsAttrAndChildArray.h) start out empty. When cloning, the array ends up being resized multiple times in order to add the attributes and children that are being cloned from the original node. This would be quicker if the array was initialized to the correct size in the first place so that resizes are not necessary.
However, preallocating space for children is only necessary when performing a deep clone. Therefore, an additional parameter is being added to the Clone, CopyInnerTo, and CloneDocHelper methods to indicate whether preallocation of children should happen. Attributes are copied either way, so that part of the array is preallocated in both cases.

This switches over from using nsStringBuffer to nsString for URLValueData's
|mString| member. This avoids various tedious conversions and can provide
potential performance improvements by avoiding length calculations.

In the next patch we want to add a method called
GetUnanimatedStyleContextForElementNoFlush but that's much too long. Instead it
seems better to just drop 'ForElement' from all these methods since it should be
fairly obvious we are getting the style context for an element given that the
first argument is an element.

The UpdateState calls in BeforeSetAttr were there in case an AttributeWillChange
observer examined the element state and expected it to be updated to whatever
changes BeforeSetAttr made. But at this point, AttributeWillChange runs before
BeforeSetAttr, and there is no code that runs between BeforeSetAttr and the
subsequent UpdateState in SetAttrAndNotify/UnsetAttr that cares or could care
about the state of the element. So it's safe to do no state updates in
BeforeSetAttr and just do the single UpdateState we already do.

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

Doing QI from nsIEditor to nsIEditorIMESupport doesn't make sense because editor should always support all methods and attributes of nsIEditorIMESupport (it does NOT mean that all nsIEditor implementation need to support IME).
This patch moves all of them to nsIEditor for avoiding redundant QIs.

This patch was written with the help of the following script. Also, manually
add mozilla qualifier to the enum values in nsStyleCoord.h, gfxRect.h, and
Types.h to make it build.
function rename() {
find .\
-type f\
! -path "./obj*"\
! -path "./.git"\
! -path "./.hg"\
\( -name "*.cpp" -or\
-name "*.h" \)\
-exec sed -i -e "s/$1/$2/g" "{}" \;
}
rename "NS_SIDE_TOP" "eSideTop"
rename "NS_SIDE_RIGHT" "eSideRight"
rename "NS_SIDE_BOTTOM" "eSideBottom"
rename "NS_SIDE_LEFT" "eSideLeft"

The only nsGenericHTMLElement::GetEditor callers are
HTMLInputElement::GetEditor/HTMLTextareaElement::GetEditor (the XPCOM-y
versions), which are only called from C++ and only from two places: a11y code,
which forces itself to look like system, and typeaheadfind, which would break
badly if it could not get an editor. So that security check simply shouldn't
exist.
The script API doesn't call down into here _and_ is [ChromeOnly] in the webidl
already.
The spec used to say that getting the .ping property on
HTMLAnchorElement or HTMLAreaElement should return a DOMTokenList of
parsed URLs, but it now says to return a plain string. All other UAs
that implement ping match the new spec, and it's hopefully unlikely that
any sites depend on our old behavior.
