Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

This is unused right now, but will allow to change media feature visibility
without servo/ changes (along with https://github.com/servo/servo/pull/18774).

This patch merges nsAtom into nsIAtom. For the moment, both names can be used
interchangeably due to a typedef. The patch also devirtualizes nsIAtom, by
making it not inherit from nsISupports, removing NS_DECL_NSIATOM, and dropping
the use of NS_IMETHOD_. It also removes nsIAtom's IIDs.
These changes trigger knock-on changes throughout the codebase, changing the
types of lots of things as follows.
- nsCOMPtr<nsIAtom> --> RefPtr<nsIAtom>
- nsCOMArray<nsIAtom> --> nsTArray<RefPtr<nsIAtom>>
- Count() --> Length()
- ObjectAt() --> ElementAt()
- AppendObject() --> AppendElement()
- RemoveObjectAt() --> RemoveElementAt()
- ns*Hashtable<nsISupportsHashKey, ...> -->
ns*Hashtable<nsRefPtrHashKey<nsIAtom>, ...>
- nsInterfaceHashtable<T, nsIAtom> --> nsRefPtrHashtable<T, nsIAtom>
- This requires adding a Get() method to nsRefPtrHashtable that it lacks but
nsInterfaceHashtable has.
- nsCOMPtr<nsIMutableArray> --> nsTArray<RefPtr<nsIAtom>>
- nsArrayBase::Create() --> nsTArray()
- GetLength() --> Length()
- do_QueryElementAt() --> operator[]
The patch also has some changes to Rust code that manipulates nsIAtom.

In addition to the sourceMappingURL comment, there is a second special
comment, "sourceURL", that can be used to set the "display name" of a
style sheet for developer tools. This name is also used as the base
URL for the source-map URL resolution algorithm. sourceURL is
described here:
https://blog.getfirebug.com/2009/08/11/give-your-eval-a-name-with-sourceurl/
This patch changes Firefox to record this URL, if specified, and to
expose it (chrome-only) vai StyleSheet.webidl.

The variables (basicShapeSVGBoxValues, etc.) in property_database.js are
moved to the beginning of the file so that they're defined before usage.

This changes the CSS lexer to extract sourceMappingURL directives from
comments and preserve them; then changes the parser to expose this value
as the style sheet's sourceMapURL.

This patch replaces four functions of the name AssignWithConversion which
are essentially wrappers around CopyASCIItoUTF16 and LossyCopyUTF16toASCII
with direct calls to the latter two functions. The replaced functions are:
void nsCString::AssignWithConversion( const nsAString& aData )
void nsString::AssignWithConversion( const nsACString& aData )
void nsTString_CharT::AssignWithConversion(
const incompatible_char_type* aData,
int32_t aLength = -1);
The last of the three exists inside the double-included nsTString* world and
so describes two functions, giving four in total.
This has two advantages:
* it removes code
* at the call points, it makes clear (from the replacement name) which
conversion is being carried out. The generic name "AssignWithConversion"
doesn't make that obvious -- one had to infer it from the types.
The patch also removes two commented out lines from
editor/composer/nsComposerCommands.cpp, that appear to be related. They are
at top level, where they would never have compiled. They look like
leftovers from some previous change.

In the an+b syntax, this continues to allow comments and spaces like so:
` an + b `. It does not allow `a n+b`, or `- an+b` or `+ an+b` (and the
same for the `an-b` form). Similarly, it does not allow `- b` or `+ b`.
Additionally, it *does* allow `+/*comment*/n+b` or `-/*comment*/n+b`,
but not `+ n+b` or `-n+b`. This is specced; in this one case we
parse two tokens but do not allow whitespace in between.

This matches how Servo handles this, which should be faster when the
value is valid, because we can skip checking lots of keyword tables
in many cases.

scrollbars.css is the only sheet which is parsed as author level, but later
added as agent level in [1]. Add a new enum value so that it can be parsed
as author level in gecko (nsCSSParser::AgentRulesEnabled() will exclude it),
but servo can recognize it as agent level sheet when the sheet is created.
Delete UserRulesEnabled() because no one uses it.
