following patch.

Before this patch, we were setting the dirty descendants bit in animation-only
restyles and it triggered unnecessary traversal for elements that does not need
the traversal (i.e no need selector matching).

It logically makes more sense for these effects to happen after the attribute has actually been changed and moving them allows us to get rid of the member variable HTMLImageElement::mForceReload.

This is necessary to facilitate the transition to cloning attributes instead of reparsing them.
HTMLImageElement's side effects proved to be a bit trickier than those of many other classes because HTMLImageElement::SetAttr intentionally forces an image reload, even if the attribute value has not been changed. Element::SetAttr, on the other hand, usually ignores attribute changes that do not change the attribute value, exiting before BeforeSetAttr is even called. In order to preserve this behavior, another virtual function |OnAttrSetButNotChanged| was added to the Element class. This function will be called in the case that Element::SetAttr exits early, allowing a forced reload to take place at that time.

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.

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 patch exists to avoid a crash in layout/style/test/test_animations.html. We end up
generating some ::before content, which causes us to style the new subtree at [1]. In
StyleNewSubtree, we fail the !postTraversalRequired assertion because
PrepareAndTraverseSubtree decided to traverse the tree twice (once to style it, and again
to restyle it for animations), and return that a post-traversal is needed.
The reason this issue happens with my NAC patches and not without is that we were previously
filtering out generated ::before content from the servo traversal, so the servo traversal
wouldn't have reached it and (presumably) the animation restyle wouldn't have happened and
we wouldn't have returned true for needing a post-traversal.

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

This fits a bit better with the other stuff, and allows us to add our new NAC
bit with the other NAC related bits, which also happens to be a field that
Servo already has easy access to.
