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.

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
(i.e. no null checks or implicit conversions to |char*|).
In every case the patch trivially replaces the nsXPIDLCString with an
nsCString. (Also, there are a couple of unused nsXPIDLCString variables that
the patch simply removes.)
This patch introduces a new registry for localization resources to replace
ChromeRegistry. It uses asynchronous I/O and iterators to generate
permutations of possible sources of language resources for use in the new
Localization API.
In the initial form the API handles packages resources and has API for
interacting with the AddonsManager which will report language packs.

This patch lands the core of the new localization API:
* Parser for the Fluent syntax called "FTL"
* Resolver for the Fluent logic
* MessageContext class which is a central class for storing and operating
on Fluent messages.

This removes about 2/3 of the occurrences of nsXPIDLString in the tree. The
places where nsXPIDLStrings are null-checked are replaced with |rv| checks.
The patch also removes a couple of unused declarations from
nsIStringBundle.idl.
Note that nsStringBundle::GetStringFromNameHelper() was merged into
GetStringFromName(), because they both would have had the same signature.
