ReferrerPolicy gets tossed back and forth as a uint32_t and
ReferrerPolicy enum in header file. Expose ReferrerPolicyValues from
webidl file and use consistently in native code.

This requires replacing inclusions of it with inclusions of more specific prefs
files.
The exception is that StaticPrefsAll.h, which is equivalent to StaticPrefs.h,
and is used in `Codegen.py` because doing something smarter is tricky and
suitable for a follow-up. As a result, any change to StaticPrefList.yaml will
still trigger recompilation of all the generated DOM bindings files, but that's
still a big improvement over trigger recompilation of every file that uses
static prefs.
Most of the changes in this commit are very boring. The only changes that are
not boring are modules/libpref/*, Codegen.py, and ServoBindings.toml.

When we unlink, we may null out the mFontFaceSet pointer, but still keep
mInFontFaceset as true. Which can cause null dereference bugs as described in
comment 0.
This is mostly a speculative fix since I think that's a plausible cause for a
bug like that, but it may not be the only cause for the crash.

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.
Referrer policy argurment is passed from sheet/doc to URLExtraData, default
value is RP_Unset. We use default value in some cases, particularly when there's
no certain spec talks about that (svg for example)

This patch is an automatic replacement of s/NS_NOTREACHED/MOZ_ASSERT_UNREACHABLE/. Reindenting long lines and whitespace fixups follow in patch 6b.

This patch does the following things:
* Create a new class ServoFontFaceRule for CSSOM of @font-face rule
which mostly follows how nsCSSFontFaceRule was implemented.
* Remove the old nsCSSFontFaceRule and binding code to create it.
* Have FontFace backed by Servo data via making mRule and mDescriptors
of the class hold RawServoFontFaceRule like ServoFontFaceRule.
To keep this patch small, it effectively just delays the conversion
from Servo data to nsCSSValue from parsing to using. This may cause
worse performance if the font set is flushed repeatedly. Supposing we
don't flush font set very frequently, it may not be a big deal.
We may still want to remove the intermediate nsCSSValue conversion at
some point, and have everything converted to their final form directly
when used, but that can happen in followups.
There are some unfortunate bits from this change:
* We lose style sheet for logging in FontFaceSet. This is probably not
all that worse, because we wouldn't have that before either if the
page doesn't use CSSOM to visit it. But we should figure out some
approach to fix it anyway.
* InspectorFontFace no longer shares the same rule object as CSSOM.
This isn't really a problem if the @font-face rule isn't very mutable.
Unless we want to make the rule returned from InspectorFontFace to be
mutable (i.e. via inspector), not using the same object probably isn't
too bad.
This patch switches the code we use to serialize stuff in FontFace and
CSSFontFaceRule, which leads to some failures in tests. Specifically,
the expected changes including:
* Value of font-family now can be serialized to identifier sequence like
font-family property. The old code always serializes it to string,
but it doesn't seem to have different requirement than the property.
Blink can serialize to identifier as well.
* Family name inside local() is also changed to use the same way as
family names elsewhere (i.e. can be identifier sequence). Blink has
the same behavior as the old code, but I don't think it's a big deal.
* The order of descriptors serialized gets changed. I don't think it
matters at all.
* Empty string as font-family via using string syntax is no longer
considered invalid for FontFace. I don't find it is mentioned anywhere
that it should be specifically treated invalid.

The new StaticPrefs machinery means that StylePrefs can be removed.
Note that this approach mirrors all static prefs into Rust, but I have only
updated structs.rs for the prefs that Stylo uses.
On a CLOSED TREE, since a sheriff closed the tree while I was about to land this
via autoland.

We have ServoCSSParser class, and I think it's better to move those
Servo FFI into this class to avoid including ServoBindings.h everywhere.

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.

Here we add a new UserFontLoadState value, STATUS_LOAD_PENDING, which
represents the state just after a gfxUserFontEntry's url()-valued source
would being loading, except that we can't start the load due to being
on a Servo style worker thread. In that case, we defer the work of
initiating the load until just after the Servo traversal is finished.
URLs that can normally be loaded synchronously, such as data: URLs
and script-implemented protocols marked as synchronous, must be
handled asynchronously when encountered during Servo traversal, since
various main-thread only work (in FontFaceSet::SyncLoadFontData) must
happen. This is a user visible change from stock Gecko, but should
only happen when font metrics for a data: URL font are requested
due to ch/ex unit resolution when layout hasn't previously requested
the font load. Hopefully nobody relies on synchronous resolution of
ch/ex units with data: URLs.
We unfortunately also can't pick gfxUserFontEntry objects out of the
UserFontCache during Servo traversal, since validating the cache
entry involves doing content policy checking, which is not thread-safe
(due in part to taking strong references to nsIPrincipals).
Platform fonts and ArrayBuffer-backed DOM FontFace objects continue
to be handled synchronously.
The PostTraversalTask does not take a strong reference to the
gfxUserFontEntry object, since it is held on to by the DOM FontFace
object, which itself won't go away before the PostTraversalTask
is run.

The PostTraversalTask does not take a strong reference to the FontFace
object, since as a DOM object, we can't call AddRef/Release on it
from the Servo style worker threads. The FontFace objects that we
encounter are all held on to by the FontFaceSet, and none of the
work that we do during font loads should drop FontFace objects
from the FontFaceSet. (That only happens under
nsIDocument::FlushUserFontSet, which is only called on the
main thread.)
