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

Original issue is that Microsoft Dynamics CRM uses invalid lang attribute in <xsl:sort>.
<xsl:sort order="descending"
select="@displayname[$sortColumnName='displayname'] |
@name[$sortColumnName='name'] |
exslt:node-set($FriendlyTypeNames)/types/type[@xmlName=current()/@datatype and $sortColumnName='datatype']"
lang="$languageName"/>
Our XSLT implementation detects "$languageName" as locale name, then use it to nsICollation.
Until Gecko 54 for Windows, even if using invalid locale name for nsICollation, it uses platform locale as fallback. But from 55, we use same implementation as macOS's to use ICU. So this issue occurs. ICU implementation doesn't use fallback locale if it is invalid.
We should use fallback locale if locale is invalid. Most code for fallback locale such as FallbackEncoding uses application locale, so use it.

HasRTLChars() appears in profile of attachment 8848015 after landing the patches
for bug 1391538 because the landing made text in <input> or <textarea> always
treated as non-single byte characters. Therefore, HasRTLChars() is now called
by nsTextFragment::SetTo() a lot in editors.
HasRTLChar() checks if it's in an RTL character for each character until it
becomes true. However, if character is less than the minimum RTL character,
U+0590, it works faster at least for Western languages.

These are all easy cases where an nsXPIDLCString local variable is set via
getter_Copies() and then is only used in ways that nsCStrings can also be used

nsStringBundle has two public methods GetStringFrom{ID,Name}() and two

Most of the names passed to nsIStringBundle::{Get,Format}StringFromUTF8Name
have one of the two following forms:
- a 16-bit C string literal, which is then converted to an 8-bit string in
order for the lookup to occur;
- an 8-bit C string literal converted to a 16-bit string, which is then
converted back to an 8-bit string in order for the lookup to occur.
This patch introduces and uses alternative methods that can take an 8-bit C
string literal, which requires changing some signatures in other methods and
functions. It replaces all C++ uses of the old methods.
The patch also changes the existing {Get,Format}StringFromName() methods so
they take an AUTF8String argument for the name instead of a wstring, because
that's nicer for JS code.
Even though there is a method for C++ code and a different one for JS code,
|binaryname| is used so that the existing method names can be used for the
common case in both languages.
The change reduces the number of NS_ConvertUTF8toUTF16 and
NS_ConvertUTF16toUTF8 conversions while running Speedometer v2 from ~270,000 to
~160,000. (Most of these conversions involved the string
"deprecatedReferrerDirective" in nsCSPParser.cpp.)

LocaleService serves two main functions. It is a central place for all code in the
engine to learn about locales, but it also does the language negotiation and selection.
The former is relevant in all processes, but the latter should only be performed
by the "main" process. In case of current Desktop Firefox, the parent process
is the one performing all the language negotiation, and content processes should
operate in the "client" mode.
In Fennec, there's a Java app on top of Gecko which should work as a "server"
and then all processes, including parent process of Gecko is merely a "client" for that.
This refactor finalizes this duality making it easily configurable to define in
which mode a given LocaleService operates.
The server-client model allows all clients to stay in sync with the server,
but operate transparently for all callers just returning the right values.
In order to initialize LocaleService in the client mode in child process with the
right locales I'm adding the list of app locales to the XPCOMInitData,
and then fire LocaleService::SetAppLocales in the child process initialization.
In order to keep the list up to date, I'm adding intl:app-locales-changed to
the list of observed topics, and when triggered, I send the updated list
to the child process, which updates LocaleService::SetAppLocales with the new
list.

StringBundle caches bundles, so when language chain changes we should

This also affects localized prefs like intl.accept_languages.

This patch fixes a regression that we hit on Fennec when we handed over control
over language negotiation to LocaleService in bug 1347306.
The problem is that we currently do not have good Android bindings for
OSPreferences::GetSystemLocale and in result we could not negotiate
languages between user-selected OS locales and available locales.
The temporary solution implemented here binds android OS preferences to
`intl.locale.os` pref which is set on Locale:OS event in browser.js.
In LocaleService we add a listener on the pref to renegotiate languages
when OS locale changes.
