It's useful to use `std::move()` to indicate the frames' ownership in one list
is transferred to the another list.
For a frame list managed by AutoFrameListPtr, after moving its frames to
another list, it can be automatically deleted when it is going out of
scope.

mozilla::ReverseIterator is required for "stashing iterators", but otherwise
std::reverse_iterator can be used and is potentially more efficient.
Also fix some other glitches in iterator type definitions.

AutoFrameListPtr might be used more frequently after we add more APIs to
handle overflow container list and excess overflow container list in
bug 1641085.
The improvements in this patch includes:
* Mark AutoFrameListPtr as MOZ_RAII and final class.
* Move AutoFrameListPtr into mozilla namespace since we don't use layout
sub-namespace that much these days.
* Remove the AutoFrameListPtr type alias in nsGridContainerFrame's
header since it's not used.

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.

The following APIs are changed.
1. Contains() needs to become contains(). (EnumSet's methods have lowercase names.)
2. Use list constructor rather than "|" like a plain enum.
3. Use operator+= instead of operator|=.

This reuses the same code path that was added in bug 1461299 for NAC, but for
generated content as well. DestroyAnonymousContent notifies to the ESM.
Also, remove the NativeAnonymousContentRemoved bit about <svg:use> since it's no
longer NAC.

Use it to implement FindFirstBlock() and FindFirstNonBlock(). This is a
demonstration on how Find() is used. The usage of them will be overhauled in
Part 2 and 3.

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.

Structs in our style system use an arena-style allocation system,
managed by the presshell to which they belong. All of the relevant
overloads that forward allocation requests to the presshell declare
themselves as CPP_THROW_NEW, which indicates that they do not throw
exceptions. The C++ specification states that operator new overloads
that declare themselves to not throw exceptions require a null check on
their return value. However, the relevant presshell allocation method,
AllocateByObjectID, is infallible and will never return a null pointer.
The callers of all of these methods are therefore doing useless
(compiler-generated) null checks. Let's get rid of those useless checks
by removing the CPP_THROW_NEW annotations. This change declares these
methods will return non-null pointers and throw exceptions in case of
errors--but as we don't use exceptions, and AllocateByObjectID will
abort on OOM, everything works out OK.

AllocateByObjectID() is infallible. Therefore the |operator new| of nsFrameList,
nsLineBox and nsRuleNode are too, as is nsRuleNode::CreateRootNode().
The patch also removes a couple of comments duplicated in both .h and .cpp
files.

This patch does the following:
* Move nsIFrame::IntrinsicSize to mozilla::IntrinsicSize so that it can
be forward-declared.
* Move a number of templated inline nsLayoutUtils methods to nsIFrame.
* Use mozilla::layout::FrameChildListID instead of the
nsIFrame::ChildListID typedef in nsLayoutUtils.h.
* Move nsReflowFrameRunnable to its only user, nsProgressMeterFrame.cpp.
* Make a number of functions requiring nsIFrame.h out-of-line.
* Remove the nsIFrame.h #include from nsLayoutUtils.h and add it to the
places which require it implicitly.
"new nsFrameList()" becomes "new (shell) nsFrameList()".
"delete list" becomes "if (list) list->Delete(shell)" - note also that
an additional assertion was added that list is empty when deleted.
"nsAutoPtr<nsFrameList> list(StealSomeFrames())" becomes
"AutoFrameListPtr list(aPresContext, StealSomeFrames())"
Add types to represent identifiers for frame child lists, sets of those
identifiers, and iterators over the child lists of a frame.
Define a enumeration type FrameChildListID representing all of the types
of child lists that frames have (each with a unique bit), a class
FrameChildListIDs for representing any set of FrameChildListID, and a
class FrameChildListIterator for iterating over all of the child lists
of a frame.
