In the presence of multiple overloads of a function taking either
QString or QStringView, QStringView should always be preferred.
The rationale is that the QStringView overload may have been
added "later" (read: the function was written when QStringView
was not available yet, so it took QString), and the fact that
a function with the _same name_ offers a QStringView overload
implies the function never needed to store/own the string in
the first place.
Add a (compile-time) test for this preference. This is in
preparation for a future QString(char16_t*) constructor
(in Qt 5.15 / Qt 6).

QString(View)s can be built or manipulated in ways that make them
contain/refer to improperly encoded UTF-16 data. Problem is,
we don't have public APIs to check whether a string contains
valid UTF-16. This knowledge is precious if the string is to be fed in
algorithms, regular expressions, etc. that expect validated input
(e.g. QRegularExpression can be faster if it can assume valid UTF-16,
otherwise it has to employ extra checks).
Add a function that does the validation.

QByteArray::fromBase64 was liberal in its input, simply skipping
over invalid characters. As a side-effect of this, it had
no error reporting, meaning it could not be used to convert
fromBase64 _and_ validate the input in one go.
Add more option flags to make fromBase64 strictly validate
its input. Since we want to know whether it has succeeded
or not, and the existing fromBase64 overloads do not
allow for that, introduce a new function that returns
an optional-like datatype.
While at it: base64 decoding can be done in-place; add an
rvalue overload to enable this use case.

This was used to support QFlags f = 0 initialization, but with 0 used
as a pointer literal now considered bad form, it had been changed many
places to QFlags f = nullptr, which is meaningless and confusing.

Released on October 4th.
Adds Windows names for two time zones, Qyzylorda and Volgograd.
Added languages Chickasaw (cic), Muscogee (mus) and Silesian (szl).
Norwegian number formatting has flipped back to using colon rather
than dot as time separator; it's flipped back and forth over the last
several CLDR releases. The dot form is present as a variant, the
colon form was long given as the normal pattern, then went away; but
now it's back as a contributed draft and that's what we pick up.
The MS-Win time-zone ID script was iterating a dict, causing random
reshuffling when new entries are added. Fixed that by doing the
critical iteration in sorted order.
Omitted locales ccp_BD and ccp_IN due to QTBUG-69324.
