Summary description: An alternative to babel for XeLaTeX and LuaLaTeX

Announcement text:
----------------------------------------------------------------------

Bug fixes:

‣ Language options are now lowercased before they are handled.
This fixes errors when using the options in \MakeUppercase
context (e.g., in headings).
‣ Fix casing value for medieval Latin (this concerns ⟨u⟩ and
⟨V⟩ casing).
‣ Remove hacks in some gloss files where \MakeUppercase has been
redefined to a no-op since the respective scripts do not have
uppercasing. As \MakeUppercase is now locale-aware, these hacks
are no longer needed. This concerns Arabic, Divehi, Hebrew,
Hindi, Kurdish, Persian, Punjabi, Syriac, and Urdu.
‣ Fix Eastern (Mashriq) Arabic numbering direction with LuaLaTeX
for Arabic, Kurdish, Persian, Syriac, and Urdu (amends previous
fix to #213).
‣ French variant=acadian refers to the Canadian French subvariety
as spoken in the Acadian region (as opposed to Quebec French).
To differentiate it we now use a dedicated subtag which can also
be used to access the language (fr-CA-u-sd-canb).
Note that Quebec French is currently connected with fr-CA,
not the more specific fr-CA-u-sd-caqc, although the u extension
is returned if requested via \BCPdata. In practice, the Canadian
subvarieties of French are identical currently, anyway.
‣ Do not blindly de-activate the quote character in languages that
provide shorthands if the shorthands are not used. This allows
to activate the character with other packages such as csquotes (#592).
‣ Do not flood the LaTeX hooks with redundant French itemlabels
and footnote settings (#593).
‣ Fix Korean patching of part format with hyperref (#595).
‣ Make Hebrew numerals expandable (#596).
‣ Avoid superfluous writing of language switches to aux file (#593).

New features:

‣ New option capitalyiwn for Armenian.
‣ New option capitaleszett for German.
‣ New option capitaliota for Greek.
‣ New option datei for Serbian.
‣ New option sectionsep for Arabic, Kurdish, Persian, Syriac,
and Urdu (#589).
‣ Add aliases eastern (= mashriq) and western (= maghrib) to
Arabic numerals.
‣ New date commands \today*, \todayGen, \todayArabic, and
\todayRoman (all with starred counterparts) for Serbian (#524).
‣ Implement basic support for variant=ijekavian in Serbian.
‣ Dutch now hyphenates properly on letters with tremata.
The new option, tremahyphenation, is provided to opt-out
this feature.
‣ Add shorthands "a, "e, "i, "o, "u, "A, "E, "I, "O, "U,
"y, and "Y to Dutch.

Interface changes:

‣ All language options are now lowercase by default (though the
mechanism is case-insensitive anyway). Changes cover Kurdish,
Sanskrit, Serbian.
