I haven't managed to find a way stuff should unexpectedly die around these
functions, so add a few diagnostics to catch this hopefully, before papering
over the bug / backing out / adding a kungfudeathgrip.

And start tracking the loader ASAP to be on the safe side.
Both sides already take care of cleaning up pointers on destruction.

All classes deriving from nsIFrame that did not have any subclasses themselves
(at the time of writing this patch) have been marked with `final`.
Some other Layout classes have also been made final, but this was opportunistic
while working on nsIFrame subclasses, and is definitely not exhaustive, further
patches welcome; refer to bug 1332680.
Advantages of marking a class final include:
- Allowing the compiler to devirtualize some method calls (i.e., calling
virtual functions directly instead of going through the vtable),
- Indicating that the class is not currently subclassed,
- Preventing subclassing without being aware that this would remove the
finalization benefits of the parent class.
`final` does not signify that these classes should *never* be subclassed, this
is left for developers to decide.

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

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 (a) moves ownership of the gfxUserFontSet into FontFaceSet, (b) moves
nearly all of the functionality of nsUserFontSet into FontFaceSet, and (c)
adds a class that inherits from gfxUserFontSet so that we can override some
of its virtual functions and delegate them to the FontFaceSet.
