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.

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.

Introduce a separate API for retrieving locale set from the host environment

In scenarios where users use OS in one locale set and the App in another,
users should be able to chose which locale set to follow for regional
preferences. This method should be used over getAppLocales for all cases
where the locales are used to format regional preferences related
items like calendars, dates, units etc.

It's silly to use prmem.h within Firefox code given that in our configuration
its functions are just wrappers for malloc() et al. (Indeed, in some places we
mix PR_Malloc() with free(), or malloc() with PR_Free().)
This patch removes all uses, except for the places where we need to use
PR_Free() to free something allocated by another NSPR function; in those cases
I've added a comment explaining which function did the allocation.

Since our platform support is Windows 7+, we can replace nsWin32Locale::GetXPLocale with LCIDToLocaleName.
LCIDToLocaleName has LOCALE_SYSTEM_DEFAULT and LOCALE_USER_DEFAULT, so we should it simply.

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.

I'm adding a helper function mozILocaleService::GetRequestedLocale to simplify
most of the callsites that are looking for the first of the requested locales.
In most cases, I'm just matching the behavior of the code with reusing
LocaleService API instead of direct manipulation on the prefs.
That includes how I handle error case scenarios.
In case of sdk/l10n/locale.js I am reusing LocaleService heuristics over
the custom one from the file since the ones in LocaleService are just
more correct and unified accross the whole platform.
In case of FallbackEncoding I have to turn it into a nsIObserver to listen
to intl:requested-locales-changed.
