cbd33cb557 Add missing dependencies of tests on their helper programs
This ensures that a command such as

  $ ninja tst_qlocale && ninja tst_qlocale_check

will automagically build the syslocaleapp program that the test runs
from a subtest. Similar for testlib's selftests and tst_QProcess.

As a drive-by, pruned some legacy comments from when CMakeLists.txt
files were generated from .pro files.

b631440902 JSON parsing: fix incorrect sign-extension for decoding bad escapes
The parser was lenient in accepting backslashes followed by invalid
characters, but accidentally sign-extended everything above 0x7f causing
broken outputs that weren't valid UTF-16 either.

For example, the sequence "\\\xff" (backslash followed by 0xff) produced
sequence "\ud7bf\udfff" (U+D7BF is not a surogate pair).

92185d417d Fix BASE argument of qt_add_resources
The BASE argument of qt_add_resources now denotes the root point of the
alias of the file.  Before, BASE was merely prepended to every file that
got passed to qt_add_resources.

Old behavior:
    qt_add_resources(app "images"
        PREFIX "/"
        BASE "../shared"
        FILES "images/button.png")

Alias is "../shared/images/button.png", and pro2cmake generated
QT_RESOURCE_ALIAS assignments to fix this.

New behavior:
    qt_add_resources(app "images"
        PREFIX "/"
        BASE "../shared"
        FILES "../shared/images/button.png")

The alias is "images/button.png".  No extra QT_RESOURCE_ALIAS assignment
is needed.

The new behavior is in effect for user projects and for Qt repositories
that define QT_USE_FIXED_QT_ADD_RESOURCE_BASE.  Qt repositories will be
ported one by one to this new behavior.  Then the old code path can be
removed.

366bdcde97 Correct prefix reported for end element in QXmlStreamReader
Before this change, QXmlStreamReader prefix value was always an empty
string for EndElement when the documentation state : "Returns the prefix
of a StartElement or EndElement."

The error was a missing update of the prefix value when parsing
EndElement.

I updated the tests data which were also wrong because no prefix were
reported even for </a:foo>. No new test is necessary, I think, the test
data already cover the cases of EndElement with a prefix and without one
(unchanged here).

58bea7f3a2 QCborStreamReader::next: don't allocate too much memory in a QBA
Because CBOR strings are encoded in UTF-8, it's possible that the string
that won't fit a QString in UTF-16 would still fit QByteArray in UTF-8
(e.g., anything US-ASCII and most Latin text).

The previous solution was an improvement because we used to read into a
QByteArray then convert the QByteArray to QString, thus using 3x the
amount of memory (1x in QByteArray, 2x in QString). The previous commit
skipped the middle allocation and made the regular readString() function
do the decoding either directly on source memory or by reading in small
chunks (16 kB).

Future improvement for Qt 6.1: add readStringChunk(char16_t *, qsizetype)
so we can do the validation / skipping at O(1) memory.

9a55f40937 QCborStreamReader: avoid allocating result if data is insufficient
By calling the internal readStringChunk() function with a QByteArray
pointer, QCborStreamReader::readByteArray() can now avoid allocating the
resulting buffer until the internals have confirmed that there is
sufficient data in the incoming buffer. As a result, we first detect the
EOF condition before we conclude the payload would have been too big for
QByteArray (validation()) test. Meanwhile, the hugeDeviceValidation()
test ends up with a few conditions where it would have copied 1 GB of
data, so limit that too.

We make a choice of reporting OOM vs DataTooLarge only if QByteArray
fails to allocate in the first place (QByteArray::resize() ->
Q_CHECK_PTR -> qBadAlloc, QtCore is always built with exceptions on).

The QCborValue unit test needed a temporary work around until we apply
the same allocation fix (see next commit).

1869615fc9 QChar: make construction from integral explicit
QChar should not be convertible from any integral type except from
char16_t, short and possibly char (since it's a direct superset).

David provided the perfect example:

  if (str == 123) { ~~~ }

compiles, with 123 implicitly converted to QChar (str == "123"
was meant instead). But similarly one can construct other
scenarios where QString(123) gets accidentally used (instead of
QString::number(123)), like QString s; s += 123;.

Add a macro to revert to the implicit constructors, for backwards
compatibility.

The breaks are mostly in tests that "abuse" of integers (arithmetic,
etc.). Maybe it's time for user-defined literals for QChar/QString,
but that is left for another commit.

[ChangeLog][Potentially Source-Incompatible Changes][QChar] QChar
constructors from integral types are now by default explicit.
It is recommended to use explicit conversions, QLatin1Char,
QChar::fromUcs4 instead of implicit conversions. The old behavior
can be restored by defining the QT_IMPLICIT_QCHAR_CONSTRUCTION
macro.

1df02b5f98 Fix conversions to JSON from QVariant
After reimplementing Qt JSON support on top of CBOR, there were
unintended behavior changes when converting QVariant{, List, Map} to
QJson{Value, Array, List} due to reusing the code for converting
QVariant* types to CBOR types, and from CBOR types to corresponding JSON
types. In particular, conversions from QVariant containing QByteArray to
JSON has been affected: according to RFC 7049, when converting from
CBOR to JSON, raw byte array data must be encoded in base64url when
converting to a JSON string. As a result QVariant* types containing
QByteArray data ended up base64url-encoded when converted to JSON,
instead of converting using QString::fromUtf8() as before.

There were also differences when converting QRegularExpression.

Reverted the behavior changes by adding a flag to internal methods for
converting CBOR to JSON, to distinguish whether the conversion is done
from QVariant* or CBOR types. These methods now will fall back to the old
behavior, if the conversion is done using QJson*::fromVariant*().

Additionally fixed QJsonValue::fromVariant conversion for NaN and
infinities: they should always convert to QJsonValue::Null. This works
correctly when converting from variant to QJsonArray/QJsonObject, but has
been wrong for QJsonValue.

Added more tests to verify the expected behavior.

[ChangeLog][Important Behavior Changes] Restored pre-5.15.0 behavior
when converting from QVariant* to QJson* types. Unforeseen consequences
of changes in 5.15.0 caused QByteArray data to be base64url-encoded; the
handling of QRegularExpression was also unintentionally changed. These
conversions are now reverted to the prior behavior. Additionally fixed
QJsonValue::fromVariant conversions for NaN and infinities: they should
always convert to QJsonValue::Null.

4a69cd7f72 Restrict comparison of variants
Comparing two variants will not try to convert the types
of the variant anymore. Exceptions are when both types are
numeric types or one type is numeric and the other one a
QString. The exceptions are there to keep compatibility with
C++ and to not completely break QSettings (which needs automatic
conversions from QString to numeric types).

[ChangeLog][Important Behavior Changes] Comparing two
variants in Qt 6 will not try attempt any type conversions before
comparing the variants anymore. Instead variants of different type
will not compare equal, with two exceptions: If both types are numeric
types they will get compared according to C++ type promotion rules. If
one type is a QString and the other type a numeric type, a conversion
from the string to the numeric tpye will be attempted.
