Rather than recording how many leaked (ghost) windows we see at
various times, I think it will be more useful over all to record what
the maximum number of ghost windows we see during a single
ping. Hopefully this will show up in a way that generates automated
alerts better than GHOST_WINDOWS.
If this works out, I'll make this telemetry measure permanent and
remove GHOST_WINDOWS.

nsStyleStructList.h was initially made generated in bug 873368 to avoid
manually maintaining boilerplate for if-dispatch, while the if-dispatch
was replaced by jump table in bug 1171842, so the boilerplate went away.
However, in bug 1122781 (before bug 1171842), boilerplate for dependency
check, so it still needs to be generated.
The dependency table is removed in the previous patch, so we no longer
have any boilerplate in the style struct list, and thus it doesn't need
to be generated anymore.

The path service was created to allow us to track resources that were part of
legacy add-ons, and to map URIs ponting to those resources to add-on IDs, so
that we could apply special behavior to them.
We have better ways to track resources belonging to WebExtensions, so this
code does not benefit them in any significant way.
The only remaining legacy extensions are system add-ons, which we control, and
do not need the path service in order to track.

A ghost window is a window that is:
a) detached
b) we think it should have gone away
c) it has been in that state for a while
Right now, criterion b holds if the detached window does not have the
same eTLD as any window that is not detached. However, this can cause
false positives when a page leaks a cross-origin iframe.
This patch changes criterion b to be that it holds if the window is
not in the same tab group as any non-detached window. This should
match better with the goal of ghost windows, which is to identify when
pages don't go away after their tab is closed.

This combines the GhostWindowsReporter with the nsWindowMemoryReporter. It has
the benefit of removing a reporter of a single value and also guarantees that
we use the latests ghost windows value that is calculated in
|nsWindowMemoryReporter::CollectReports| rather than a possibly cached value
from a previous run.

This change requires new code to measure HashMaps, which uses the new
'malloc_enclosing_size_of' functions that can measure a heap block from an
interior pointer.
The patch changes MallocSizeOfFn to a newtype, and introduces
MallocEnclosingSizeOfFn alongside.
It also adds new traits: MallocSizeOfBox, MallocSizeOfVec, MallocSizeOfHash.
These each contain a single method that does shallow measurement of the
relevant type, which is often useful. (This is a different style to the
existing MallocSizeOf trait, which does deep measurement, but I'm moving away
from the always-deep-measurement style because it's less flexible.)

This patch splits up the existing "layout/style-sets" measurement into
"layout/gecko-style-sets", or "layout/servo-style-sets/stylist/rule-tree" and
"layout/servo-style-sets/other". (Additional things will be measured under
"layout/servo-style-sets/" later, such as cascade data.)
This requires introducing a new type, ServoStyleSetSizes, for transferring the
multiple measurements from Rust code to C++ code.

This patch just moves code around, so that the reporting is done in the same
order that the nsWindowSizes fields are declared. This makes it easier to see
whether anything has been missed.

This patch moves measurement of ComputedValues objects from Rust to C++.
Measurement now happens (a) via DOM elements and (b) remaining elements via
the frame tree. Likewise for the style structs hanging off ComputedValues
objects.

The 'servo-style-structs' and 'computed-values' sub-trees are new. (Prior to
this patch, ComputedValues under DOM elements were tallied under the the
'dom/element-nodes' sub-tree, and ComputedValues not under DOM element were
ignored.) 'servo-style-structs/sundries' aggregates all the style structs that
are smaller than 8 KiB.
Other notable things done by the patch are as follows.
- It significantly changes the signatures of the methods measuring nsINode and
its subclasses, in order to handle the tallying of style structs separately
from element-nodes. Likewise for nsIFrame.
- It renames the 'layout/style-structs' sub-tree as
'layout/gecko-style-structs', to clearly distinguish it from the new
'layout/servo-style-structs' sub-tree.
- It adds some FFI functions to access various Rust-side data structures from
C++ code.
- There is a nasty hack used twice to measure Arcs, by stepping backwards from
an interior pointer to a base pointer. It works, but I want to replace it
with something better eventually. The "XXX WARNING" comments have details.
- It makes DMD print a line to the console if it sees a pointer it doesn't
recognise. This is useful for detecting when we are measuring an interior
pointer instead of a base pointer, which is bad but easy to do when Arcs are
involved.
- It removes the Rust code for measuring CVs, because it's now all done on the
C++ side.

This patch does the following.
- Moves nsWindowSizes from nsWindowMemoryReporter.h to its own file,
nsWindowSizes.h, so it can be included more widely without exposing
nsWindowMemoryReporter.
- Merges nsArenaMemoryStats.h (which defines nsTabSizes and nsArenaMemoryStats)
into nsWindowSizes.h.
- Renames nsArenaMemoryStats as nsArenaSizes, and nsWindowSizes::mArenaStats as
nsWindowSizes::mArenaSizes. This is the more usual naming scheme for such
types.
- Renames FRAME_ID_STAT_FIELD as NS_ARENA_SIZES_FIELD.
- Passes nsWindowSizes to PresShell::AddSizeOfIncludingThis() and
nsPresArena::AddSizeOfExcludingThis(), instead of a bunch of smaller things.
One nice consequence is that the odd nsArenaMemoryStats::mOther field is no
longer necessary, because we can update nsWindowSizes::mLayoutPresShellSize
directly in nsPresArena::AddSizeOfExcludingThis().
- Adds |const| to a few methods.
