The patches fix ambiguity between a getter and a signal by changing the
getter name, but we still have to rename the signal to follow the signals

924b97d6ab Fix QDateTimeEdit's handling of invalid time in dst gap
During a spring forward, a time-zone omits an hour. A QDateTime with
such an hour is invalid, but QDateTimeEdit's handling of this invalid
time was not done correctly.

With this fix, up/down changes of any field that would result in an
invalid date-time corrects the time to be valid, while leaving as
much as possible of the user-entered data unchanged. To do that, we
rely on QDateTime::toMSecsSinceEpoch to return a value even for such
an invalid time, which then can be used to construct a valid
QDateTime.

Edits that would result in an invalid hour are reverted to the
previous when pressing return, if correctionMode is
CorrectToPreviousValue. This change also implements support for
CorrectToNearestValue, which uses the same mechanism as when stepping
over an invalid time.

Include a test that verifies that the various interactions result
in a reasonable value. Since QDateTimeEdit does not respect the
timezone or timespec of the QDateTime it is initialized with, we
have to find the first hour of daylight saving time for a year
that we know works for most time zones. Failing that, we have to
skip the tests. Verified in a wide range of time zones.

0ad4f86729 Purge QRegExp use in QDateTime's rfcDateImpl()
Replace with a parser which actually does the job right, fixing
various infelicities in the parsing in the process.
Make the parser strict about formatting.

Adjusted tests to match. Fixed some QTime invalidity tests to each
test only one invalidity at a time (the invalid year and day tests
also used an invalid month).

[ChangeLog][QtCore][QDateTime] The parser for the Qt::RFC2822Date
format is now stricter, requiring the text to exactly match the form
of one of the relevant formats. A valid date or time will still be
parsed, even if the other part of the content is invalid, as long as
it (and any offset, if present) has the right form. In particular, the
parser now rejects texts with trailing cruft (other than space).

fd4be84d23 Add an expansion limit for entities
Recursively defined entities can easily exhaust all available
memory. Limit entity expansion to a default of 4096 characters to
avoid DoS attacks when a user loads untrusted content.

Added a setter and getter to allow modifying the expansion limit.

[ChangeLog][QtCore][QXmlStream] QXmlStreamReader does now by default
limit the expansion of entities to 4096 characters. Documents where
a single entity expands to more characters than the limit are not
considered well formed. The limit is there to avoid DoS attacks through
recursively expanding entities when loading untrusted content. The
limit can be changed through the QXmlStreamReader::setEntityExpansionLimit()
method.

e5acaa12e3 QObject: treat T* -> bool conversions as narrowing
Following wg21.link/LWG3228, it was found that a proper variant fix
requires that T* -> bool conversions be treated as narrowing
conversions in subclause wg21.link/dcl.init.lst. wg21.link/P1957R2 was
accepted in Prague 2020 as a DR and retroactively applies to older C++
standards.

Since we hard-code the algorithm of [dcl.init.lst], we can and must
add this manually.

[ChangeLog][QtCore][QObject] For the purposes of
QT_NO_NARROWING_CONVERSIONS_IN_CONNECT, pointer
(incl. pointer-to-member) to bool conversions are now considered
narrowing. This matches the resolution of a defect report in C++
itself.

c58ee54a70 tst_qtcpsocket::bind - amend the recent fix
0. The recent patch fixed the case when we can suddenly (meaning from
a particular version of Darwin) bind on a port number 1. Unfortunately,
it's not the case for IPv4 and while fixing one test case, the patch broke
another - so this patch addresses this.
1. Unfortunately, binding on a fixed port 1 on macOS made the test flaky
- we run this 'bind' several times and sometimes OS thinks port is already
bound (because of the previous test case) - closing the connection seems
to fix this problem (thus this patch do this also).
2. As a bonus a proper resource management added (aka RAII) where we would
previously leak a socket in case some QCOMPARE failed.

962a3d8a98 Stabilize QFileSystemModel::dirsBeforeFiles test
Make the test operate in its own temporary directory, so that entries
left behind by other test functions don't impact this test.

Also, call QFileSystemModel::sort explicitly; it would otherwise only
be done once through a single-shot timer, and the test processes events
until the model is populated, which might not process that delayed
sorting. Since dirsBeforeFiles tests the sorting algorithm and not
the sorting logic, best to do this explicitly.

In case of sort failure, print diagnostics.

1821f5163d Fix font and palette propagation for themed children created at runtime
Widgets have a default palette and font that is influenced by several
factors: theme, style, QApplication-wide overrides, and the parent's.
If an application sets a font or palette on a parent, then widgets
inherit those settings, no matter when they are added to the parent.

The bug is that this is not true for widgets that have an application-
wide override defined by the platform theme. For those, we need to merge
parent palette and font attributes with the theme, and this is currently
not done correctly, as the respective masks are not merged and inherited.

This change fixes this for fonts and palettes. Children are inheriting
their parent's inheritance masks, combined with the mask for the
attributes set explicitly on the parent. This makes the font and palette
resolving code correctly adopt those attributes that are set explicily,
while leaving everything else as per the theme override.

The test verifies that this works for children and grand children added
to a widget that has a palette or font set, both when themed and
unthemed. Children with own entries don't inherit from parent.

The QFont::resetFont test had to be changed, as it was testing the
wrong behavior. If the child would be added to the parent before the
font property was set, then the test would have failed. Since this
change makes sure that children inherit fonts in the same way, no
matter on when they are added to their parent, the test is now
modified to cover both cases, and ensures that they return identical
results.

[ChangeLog][QtWidgets][QWidget] Fonts and palette settings are inherited
by children from their parents even if the children have application-
wide platform theme overrides.

f9086ebd01 QShaderGenerator: Allow more expressions in input nodes
Currently QShaderGenerator will crash when encountering some expressions
in input nodes.

For example, this node prototype would make it crash:
"VERTEX_COLOR": {
  "outputs": ["color", "alpha"],
  "rules": [
    "headerSnippets": ["in vec4 vertexColor;"],
    "substitution": "vec3 $color = vertexColor.rgb;
                     float $alpha = vertexColor.a;"
  ]
}
