Note that nsMathMLContainerFrame and its subclasses are unchanged since
they are not target of fullscreen (and thus no backdrop frame), and they
have an assertion to ensure we really don't pass any unexpected list in.
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.

In inline layout there's no need to do anything with overflow areas
since RelativePositionFrames handles it. Apparently doing some of the
work messes things up somehow, so the easy fix is to make the inline
::first-letter codepath behave more like nsInlineFrame and not do any
messing with overflow areas. So this moves the rest of the overflow
code in nsFirstLetterFrame::Reflow into the float-only codepath. There
don't appear to be any ordering issues with the movement, since the code
that the FinishAndStoreOverflow call is moved across deals with creating
and destroying continuations of the child.
All the added tests pass with the patch, but without the patch
overflow-inline-nooverflow.html fails.
This is the actual fix for the bug. This changes the vertical sizing of
inline ::first-letter frames to work like inlines (and size based on
font metrics), so that the line-height calculation that happens later
will produces the same results as inlines would produce.
In the case we're concerned with of having a text frame child that's
0x0, this changes the inline ::first-letter from from being 0x0 to
having a height that is determined from the font metrics.
There's no need for these calls to be done in the inline ::first-letter
codepath.
In particular, nsLineLayout::ReflowFrame (called a few lines above)
calls SetRect and DidReflow, while nsLineLayout::RelativePositionFrames
(which is called at the end of inline reflow) calls
FinishAndStoreOverflow.
This patch makes no changes other than duplicating the code previously
after the if/else on both branches of the if/else.
The next two patches in this series will completely rewrite the half in
the non-floating (i.e., inline) codepath (the else branch).
This changes this code to do things in the normal way, which is to use a
separate nsHTMLReflowMetrics for each Reflow, rather than (as this code
was) reusing the one for the nsFirstLetterFrame for its text frame
child.
