We previously (in bug 1491235) adjusted some utility code to make
layout-contained frames behave as if they have no baseline.
But that's not sufficient. To make frames fully report lack-of-a-baseline,
we now do the following for layout-contained frames, as of this patch:
(a) We now leave the ReflowOutput outparam's BlockStartAscent member at its
default value (which is what we do for frames without a baseline like
e.g. nsCheckboxRadioFrame and nsHTMLCanvasFrame). And if the parent cares
about the baseline, it'll then ask directly, using a baseline getter.
(b) We now return 'false' in more implementations of bool-returning
baseline-getter-methods (where 'false' indicates 'no baseline').
(c) We now return the margin-box-bottom edge, in the nscoord-returning
'GetLogicalBaseline()' getter method. (We typically do this by deferring
to the inherited method, which ultimately comes from nsFrame's
implementation). It's appropriate to use the margin-box-bottom edge when
there's no baseline, per the definition of 'vertical-align: baseline',

This patch changes remaining things under `layout/`. However, there are some
places which still need to use `nsIPresShell`. That will be fixed in a
follow up bug.

Additionally, this patch makes `nsFrame.h` stop including `nsIPresShell.h`
and makes each users include `mozilla/PresShell.h` instead. So, this improves
rebuild performance of `nsIPresShell.h` (and `mozilla/PresShell.h` in the
future).
Note that due to `nsIFrame::PresShell()`, `mozilla::` prefix is necessary for
`PresShell` in a lot of classes which are derived from `nsIFrame` even in
`.cpp` files.

`nsPresContext` should use `mozilla::PresShell` directly instead of
`nsIPresShell`. This patch makes it.
Unfortunately, `nsPresContext` and `nsIFrame` have `PresShell()`. Therefore,
we cannot use `PresShell*` in its methods so that this patch uses `mozilla::`
namespace prefix.
It might be better to rename them as `PresShellPtr()` in another bug.

This also adopts the resolution from [1] while at it, making letter-spacing
compute to a length, serializing 0 to normal rather than keeping normal in the
computed value, which matches every other engine.
This removes the SMIL tests for percentages from letter-spacing since
letter-spacing does in fact not support percentages, so they were passing just
by chance.

This is more consistent with what the Rust bits of the style system do, and
removes a pointer from ComputedStyle which is always nice.
This also aligns the Rust bits with the C++ bits re. not treating xul pseudos as
anonymous boxes. See the comment in nsTreeStyleCache.cpp regarding those.
Can't wait for XUL trees to die.

Really sorry for the size of the patch :(
Only intentional behavior change is in the uses of HasLengthAndPercentage(),
where it's easier to do the right thing. The checks that used to check for
(IsCalcUnit() && CalcHasPercentage()) are wrong since bug 957915.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..

We do the following:
CreateRootNode();
nsresult rv = BindToFrame(this);
NS_ENSURE_SUCCESS(rv, rv);
aElements.AppendElement(mRootNode);
That means that if BindToFrame fails, mRootNode will never be appended to
aElements, and thus will never get the native anonymous bits in [1].
BindToFrame should assert, but it indeed can fail due to it being bound to a
different frame in print preview, because nsCSSFrameConstructor's
ReplicateFixedFrames is a massive hack. :(
Just ensure the NAC bit is properly set for now...

This method is not a virtual call, and also looks nicer.
This patch was mostly generated by a Python script, but I manually
cleaned up the code in a few places where statements didn't need to be
split across multiple lines any more.

This patch basically does:
* remove StyleSetHandle and its corresponding files
* revisit #includes of related header files and change correspondingly
* change nsIPresShell::mStyleSet to be UniquePtr<ServoStyleSet>
* change the creating path of ServoStyleSet to pass UniquePtr
* change other mentions of StyleSetHandle to ServoStyleSet*
* remove AsServo() calls on ServoStyleSet
Some unfortunate bits:
* some methods of (Servo)StyleSet only accepts ServoStyleSheet while
many places call into the methods with StyleSheet, so there are many
->AsServo() added to sheets
