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 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.

The NS_LITERAL_CSTRING macro creates a temporary nsLiteralCString to encapsulate the string literal and its length, but AssignLiteral() can determine the string literal's length at compile-time without nsLiteralCString.

Add additional logic to our language negotation to do apply likelySubtags when a direct match is not available.
Currently, if the user specifies the locale with region, and we do not have a direct for that region, we pick all locales for the same language and other regions in no order.
The example of where it returns suboptimal results:
1) Requested locale "en-CA"
2) Available locales ["en-ZA", "en-GB", "en-US"]
3) Negotiated locales ["en-ZA", "en-GB", "en-US"]
This would not happen, if the user requested a generic "de", "en" etc.:
1) Requested locale "en"
2) Available locales ["en-ZA", "en-GB", "en-US"]
3) Negotiated locales ["en-US", "en-ZA", "en-GB"]
because after not finding a direct match, we would use likelySubtags to extend "en" to "en-Latn-US" and then find the priority match in "en-US".
This patch extends this logic to "en-US" or "de-LU" by adding a step which strips the region tag and then applies likelySubtag on the result.
This means that in absence of direct match the following fallbacks would happen:
"de-LU" -> "de-DE"
"es-CL" -> "es-ES"
"en-CA" -> "en-US"
This does not affect languages that use multiple scripts, so ar, sr and zh are not affected.

By the time the LocaleService destructor is called, by definition sInstance
has been cleared and its preference observers have been removed, since both
are strong references. In practice, this doesn't seem to cause trouble, but it
does lead to worrying warnings at shutdown in debug builds, which are annoying
red herrings when debugging other issues.

Until Firefox 54, font fallback uses user locale. Example, OS is Windows 10 JA with JA UI, Firefox uses JA font for fallback even if Firefox is US version.
But since we changed some locale code on Firefox 55 development cycle, there were some regressions such as bug 1346674. So we changed fallback locale to system locale (instead of Firefox UX locale) for font selection by bug 1348259.
It isn't good for old compatibility, so we should use user locale for font fallback like Firefox 54. Now we can get user locale by OSPreferences::GetRegionalPrefsLocales, use it for font fallback

This should be the only callee affected, given
gfxPlatformFontList::GetFontPrefLangFor already uses case-insensitive string
comparison.
This makes it also consistent with the rest of the functions in the file, which
lowercase their inputs as well.
