300aaec2f9 Fix digit grouping when digits are surrogat pairs
This is a follow-up to commit ed2b110b6a
to fix indexing errors. Added the test that should have accompanied
that commit, which found some bugs, and refined the Indian number
formatting test (on which it's based).

Make variable i in the loops that insert grouping characters in a
number be consistently a *character* offset - which, when each digit
is a surrogate pair, isn't the same as an index into the
QString. Apply the needed scaling when indexing with it, not when
setting it or decrementing it. Don't assume the separator has the same
width as a digit.

Differences in index no longer give the number of digits between two
points in a string, so actively track how many digits we've seen in a
group when converting a numeric string to the C locale. Partially
cleaned up the code for that in the process (more shall follow when I
sort out digit grouping properly, without special-casing India).

9121829916 QRegularExpression: rename AnchoredMatchOption to AnchorAtOffsetMatchOption
The name of the option may cause confusion due to the fact
that it's not _fully_ anchoring the match, only anchoring it
at the offset passed to match() -- in other words, it's a
"left" anchoring. Deprecate the old name and introduce
a new one that should explain the situation better.

[ChangeLog][QtCore][QRegularExpression] The AnchoredMatchOption
match option has been deprecated in favor of
AnchorAtOffsetMatchOption, which should better describe
that the match is only anchored at the offset.

less by accident) on standard formats. In particular, this now means

c58249c327 tst_qstringapisymmetry: start testing char16_t, too
No surprises, as char16_t is transparently handled by QChar overloads.

Ok, one surprise: we seem to have QChar <> QByteArray relational
operators, but they don't work for char16_t. Probably members of
QChar, so LHS implicit conversions are disabled. Didn't investigate,
because it needs to be fixed at some point anyway, but that point is
not now.

ed2b110b6a Allow surrogate pairs for various "single character" locale data
Extract the character in its proper unicode form and encode it in a
new single_character_data table of locale data. Record each entry as
the range within that table that encodes it. Also added an assertion
in the generator script to check that the digits CLDR gives us are a
contiguous sequence in increasing order, as has been assumed by the
C++ code for some time. Lots of number-formatting code now has to take
account of how wide the digits are.

This leaves nowhere for updateSystemPrivate() to record values read
from sys_locale->query(), so we must always consult that function when
accessing these members of the systemData() object. Various internal
users of these single-character fields need the system-or-CLDR value
rather than the raw CLDR value, so move QLocalePrivate's methods to
supply them down to QLocaleData and ensure they check for system
values, where appropriate first.

This allows us to finally support the Chakma language and script, for
whose number system UTF-16 needs surrogate pairs.

Costs 10.8 kB in added data, much of it due to adding two new locales
that need surrogates to represent digits.

[ChangeLog][QtCore][QLocale] Various QLocale methods that returned
single QChar values now return QString values to accommodate those
locales which need a surrogate pair to represent the (single
character) return value.

- ibid., called with non-ascii content and CaseInsensitive fails
  (this was discussed on the ML, with tentative agreement that
  it's a feature, not a bug; waiting for QUtf8String(View) for a
  fix, then).
- As was the case when we did this exercise with the relational
  operators, QString(Ref)/QChar is not noexcept (will fix)

These have been QEXPECT_FAIL'ed.

Not much of the cartesian product is implemented at all, yet.  These
have been #ifdef'ed with NOT_YET_IMPLEMENTED to see what's still
missing.

4e7af2061e Merge remote-tracking branch 'origin/wip/cmake' into dev
This pulls the CMake port, which not only adds CMake files but also
modifies existing code. A brief summary of "seemingly unrelated" changes:

    * configure.json was re-formatted to not use multi-line strings. That
      is an extension of the Qt JSON parser but not JSON compliant, which
      is needed for the configure.json-to-cmake conversion script (python).
    * Some moc inclusions were added due to CMake's slightly different way
      of handling moc. With the changes the files build with qmake and cmake.
    * Since CMake just grep's for the Q_OBJECT macro to determine whether to
      call moc (instead of doing pre-processing like qmake), the existing use
      of "Q_OBJECT" in our documentation was changed to \Q_OBJECT, which cmake
      doesn't see and which is now a qdoc macro.
    * QTestLib's qFindTestData was extended to also search in the source
      directory known at build time.

What this change also brings is a new way of building modules in Coin by using
YAML configuration files that describe the steps of building and testing in Coin
specific terms. The platform configuration files in qt5 are instructed to use the
old Coin built-in way of testing ("UseLegacyInstructions" feature) but for any
configurations that do not have this, these yaml files in the coin/ sub-directory
are used and shared across repositories.

71fa90a37c Enable system locale to skip digit-grouping if configured to do so
On macOS it's possible to configure the system locale to not do digit
grouping (separating "thousands", in most western locales); it then
returns an empty string when asked for the grouping character, which
QLocale's system-configuration then ignored, falling back on using the
base UI locale's grouping separator. This could lead to the same
separator being used for decimal and grouping, which should never
happen, least of all when configured to not group at all.

In order to notice when this happens, query() must take care to return
an empty QString (as a QVariant, which is then non-null) when it *has*
a value for the locale property, and that value is empty, as opposed
to a null QVariant when it doesn't find a configured value. The caller
can then distinguish the two cases.

Furthermore, the group and decimal separators need to be distinct, so
we need to take care to avoid cases where the system overrides one
with what the CLDR has given for the other and doesn't over-ride that
other.

Only presently implemented for macOS and MS-Win, since the (other)
Unix implementation of the system locale returns single QChar values
for the numeric tokens - see QTBUG-69324, QTBUG-81053.

We have long (since 4.5.1) coerced it to lower-case, for no readily
apparent, much less documented, reason. CLDR says most locales use an
upper-case E for this - let's actually use what CLDR says we should
use.

The code that matches the exponent separator was doing so
case-insensitively in any case; that needed adaptation now that the
separator's case isn't pre-determined; and, in any case, should have
been done using case-folding rather than upper-casing. In the process,
removed some spurious checks for "'e' or 'E'" in the result, since the
exponent separator is always represented by 'e' (and an 'e' might also
be present for the separate reason of its use as a beyond-decimal
digit representing fourteen).

[ChangeLog][QtCore][QLocale] QLocale::exponential() now preserves the
case of the CLDR source, where previously it was lower-cased.

577d698b8e QString::isLower/isUpper: redo the implementation
Use QStringIterator rather than indexed loops. This fixes handling of
non-BMP code points (which may be lower or uppercase, see the test).

Change also the semantics of the functions, adopting Unicode §3.13
definitions: a string is lowercase/uppercase if it's equal to its
own toLower/toUpper folding.

As a side effect, empty strings are now correctly reported to be
lowercase AND uppercase.

[ChangeLog][Important Behavior Changes] The semantics of
QString::isLower() and QString::isUpper() have been changed to match the
Unicode specification. Now lowercase (resp. uppercase) strings are
allowed to contain any character; a string is considered lowercase
(resp. uppercase) if it's equal to its own toLower() (resp. toUpper())
folding.  Previously, a non-letter character would make the string not
lowercase nor uppercase, and the mere presence of an uppercase (resp.
lowercase) letter would make isLower() (resp. isUpper()) return false,
even if the letter wouldn't change under case folding.  As a
consequence, now empty strings are lowercase and uppercase.

[ChangeLog][QtCore][QString] Fixed a number of bugs of
QString::isLower() and QString::isUpper(). Empty strings are now
correctly reported to be lowercase (resp. uppercase), and strings
containing code points outside the BMP are now correctly handled.
Note that the behavior of these functions has also been changed.

50f3ccd782 QStringView: add a test for overload resolution versus QString
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).

a2ddd96ac8 Introduce QString(View)::isValidUtf16
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.

[ChangeLog][QtCore][QStringView] Added QStringView::isValidUtf16.

[ChangeLog][QtCore][QString] Added QString::isValidUtf16.
