Marc Mutz aa37e67ef7 Port from qAsConst() to std::as_const()
We've been requiring C++17 since Qt 6.0, and our qAsConst use finally
starts to bother us (QTBUG-99313), so time to port away from it
now.

Since qAsConst has exactly the same semantics as std::as_const (down
to rvalue treatment, constexpr'ness and noexcept'ness), there's really
nothing more to it than a global search-and-replace, with manual
unstaging of the actual definition and documentation in dist/,
src/corelib/doc/ and src/corelib/global/.

Thiago Macieira a94731c2ad tst_QTcpServer: use a random port number in addressReusable
Just in case the same test is being run in parallel. We do that by
creating a listening TCP server in the test process. This test is
supposed to test the address reusability, so a clean close on a server
that never accepted a connection should not cause reusability issues.

Edward Welbourne 97470a7838 tst_QUuid::fromString(): tweak a test to avoid data-tag collision
Two of the uuidA test cases had an open-brace for the string and no
close; one of them ended with a space (which, apparently, is valid).
Since the data-tag was constructed by formatting the string in a
fixed-width field, padding with spaces, these two cases coincided.

Fortunately the only uuidB test-case had closing as well as opening
braces, so we can just switch the test for "trailing space is not an
error" to use it, instead.

Volker Hilsheimer 2ef130a41d JNI: add generic support for array-types
The typeSignature for a type T[] is always "[" + typeSignature<t>, so we
can just implicitly support arrays of any known type. To prevent support
for multi-dimensional arrays, make sure that the underlying type is not
also an array.

By adding a QJniTypes::isArrayType in addition (that is true for any
type with a signature starting with '['), methods like
QJniObject::callMethod could then return a special QJniArray type that
provides array-specific functionality.

As a drive-by, and since all lines need to be touched to add braces,
replace std::is_same<>::value with std::is_same_v.

Volker Hilsheimer 109e088c7c Make sure that palette cache keys are unique
After 1d961491d8, palettes are different
if they either have different brush data, or a different private. Two
privates can share data, but still must generate different cache keys.
The cacheKey has so far been composted of the serial number of the Data
struct, and a detach number that is incremented when we detach the
private.

This failed for two reasons:

- the implicit copy constructor of the Data class copied the serial
number, when it should have incremented it. Fix that by member-
initializing the serial number rather than doing it only in the default
constructor. The member initialization is also executed for the copy
constructor.

- the detach_no logic as it was implemented does not guarantee that two
copies of the same palette that share data, but have different resolve
masks (and thus different privates) have different detach_no values.
Use a static serial counter for that number as well.

Amend the test case to verfiy that cache keys, and the elements of the
cache keys, change when they are expected to.

Eskil Abrahamsen Blomfeldt 1fe7144a07 Introduce QGlyphRun::stringIndexes()
This introduces a way to trace each entry in the glyph index
array to a specific index in the original text passed to
QTextLayout, as well as a convenience function to access
the original string from the QGlyphRun.

The index information is stored in the logClusters array internally
in Qt, but it contains the inverse information: For each
character in the output string, it contains an index into the
glyph array. In order to get the string indexes for each glyph,
which makes a lot more sense in the context of the QGlyphRun
API, we need to do a little search to construct the data.

To avoid adding unnecessary allocations, we make the new APIs
opt-in. If you do not specify anything, you will only get the
glyph indexes and glyph positions as before. However, you
can now specify exactly which parts of the layout to extract
using an optional flags parameter.

This also adds a manual test which can be very handy to
visualize QTextLayouts and how they are split into QGlyphRuns.

Giuseppe D'Angelo 42b66bd809 QTaggedPointer: disable operator= with an empty initializer list
Given a QTaggedPointer, users may write

  taggedPtr = {};

to mean "reset it". This is error-prone: due to overload resolution,
this actually ends up calling QTaggedPointer<T>::operator=(T *),
which changes the pointer but *not* the tag, and not the implicitly
declared QTaggedPointer<T>:operator=(const QTaggedPointer<T> &)
which would reset both pointer and tag.

Given the idiomatic usage of {} is indeed to perform a full reset (cf.
std::exchange(obj, {}), std::take, etc.), work around this by disabling
the operator= overload for pointers in case an initializer list is
passed. In other words, make `={}` fall back to the implicitly
declared overload.

Note, this breaks some usages, such as

  taggedPtr = {rawPtr};

but at least we get a compile error for these, and they don't look
common at all.

[ChangeLog][QtCore][QTaggedPointer] The operator assignment
taking a raw pointer has been reimplemented in order to avoid
subtle issues when assigning `{}` to a QTaggedPointer. This will
cause code that assigns a braced-init-list to a QTaggedPointer object
to stop compiling (for instance, `tagPtr = {ptr}` is now ill-formed).

Edward Welbourne 18439a449f Support serializing time-zone fields in date-times more flexibly
[ChangeLog][QtCore][QDateTime] The 't' format character in a
toString() template can now be repeated to get alternatives to the
(unparseable) zone abbreviation. Thus 'tt' now gets the zone offset
without colon, [+-]hhmm; 'ttt' gets the same with colon, [+-]hh:mm,
and 'tttt' gets the zone name. Previously, each 't' was replaced by
another copy of the abbreviation.

Edward Welbourne 0bc92c01e3 Support parsing time-zone specifiers more selectively
[ChangeLog][QtCore][QDateTime] The 't' format used in fromString() can
now be repeated to restrict parsing to particular forms. Thus 'tt' now
matches the [+-]hhmm offset format (no colon), 'ttt' the [+-]hh:mm
offset format (with colon), and 'tttt' matches an actual zone
name. When used singly, 't' still matches anything the parser knows
how to interpret as a zone specifier.

repeated forms, as for QDateTime::fromString().
