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.
CLOSED TREE makes big refactorings like this a piece of cake.

This is the second of two big chunks of code moved into the new
RestyleManager class from another sources.
Note that the undisplayed map remains in nsFrameManager, although it
could perhaps have moved.
This is needed for the following patch, which leaves the undisplayed map
in nsFrameManager rather than moving it to RestyleManager (I think one
could argue for either way, but it was easier not to move it).
This propagates the non-inherited (in the nsChangeHint sense, not the
CSS inheritance sense) parts of the parent's change hint through
ReResolveStyleContext so that we can use them in
nsStyleContext::CalcDifference. In the cases where we don't know the
parent's hint, we assume the worst, that all the non-inherited hints
were present in the parent's style change.
This should be a significant performance improvement handling simple
style changes (such as a style attribute change setting a non-inherited
property) on elements with large numbers of descendants that have data
in ForceCompare structs that can't be stored in the rule tree (for
example, margins or widths in em or rem units).
