cb612491b3 tests/manual/widgets/styles: Extend the style icon display
Refactor the page displaying the standard pixmaps of a style:
- Use a QGroupBox
- Sort items by enumeration name

Add a page displaying the standard icons along with the list of
sizes.

This allows for conveniently checking which resolutions are available.

43c44d05ca Update the overflow functions to include qsizetype
Commit 29bc68cf16 added support for
unsigned and commit 5ff7a3d96e later added
support for int. This commit adds support for qsizetype, which isn't int
on 64-bit platforms.

We do this by reorganizing the code and using the generic version of
__builtin_{add,sub,mul}_overflow from GCC 5 and Clang 3.8, which ICC 18
seems to support now too on Linux. That leaves older versions of GCC and
Clang, as well as MSVC, ICC on Windows, and the GHS compiler, to use the
generic implementations, as I've removed the assembly code those
versions of GCC and Clang on x86 are now uncommon.

Note: any older version of ICC probably breaks. We only support the
latest.

4d898a73e6 QMenuBar: Fix repetitive emission of triggered() when using addAction(QString)
The action which added by QMenuBar::addAction(const QString &text) already
connected relevant signals and slots implicitly, however, while
QMenuBarPrivate::updateGeometry -ing, it reconnects them
if there's a extension button associated with a hidden popup menu.
In that case the QMenuBar::triggered would be fired twice.
Since the QAction's ownership may be changed or added dynamically,
there are still very rare cases like several widgets share the same
QAction object to result in this problem.

on top of an older file. When QFile::open is called with the
ExistingOnly flag, the call will fail if the file does not exist. The
ExistingOnly flag only provides new functionality when used with the
WriteOnly flag. For ReadOnly it provides no change in functionality,
as ReadOnly by itself already never creates.

85aa0fd041 Introduce QIcon::fallbackSearchPaths()
... that will be used if an icon can't be found in the
current theme.

The Icon Theme Specification
https://standards.freedesktop.org/icon-theme-spec/latest/ar01s05.html
states that unthemed icons must be searched in the base directories,
i.e. /usr/share/icons, ... But in practice unthemed icons are
installed into /usr/share/pixmaps and this dir is not used as
a base dir for icon themes. So it's better to explicitly specify
fallback dirs to avoid needless access to the filesystem.

Also some KDE application install their own unthemed icons
(into /usr/share/<appname>/pics), that can't be found by
QIconLoader. With this change it would be possible for them
to specify dirs with unthemed icons and thus be displayed
correctly in non-KDE environments.

[ChangeLog][QtGui][QIcon] Added fallbackSearchPaths() that
will be used to find icons missing in the current icon theme.

abbd26f553 Add QModelIndex::siblingAtColumn and ::siblingAtRow
Data in item models is most often organized in rows, where each column
contains an attribute of the item represented by the row. Often when
sibling is used, it is to request another piece of data from the same
row. Having a specialized version makes this easier and less awkward
to do, simplifying

auto sibling = index.sibling(index.row(), columnOfInterest);

to

auto sibling = index.siblingAtColumn(columnOfInterest);

For symmetry reasons, siblingAtRow(rowOfInterest) was also added.

b14934547a Use TESTDATA for QSsl* tests
Apparently this (undocumented) TESTDATA feature creates resource files,
but lets you use wildcards as well, which is very handy.

The reason I didn't know/realize this when adapting the tests to use a
".qrc"-file* was because some of the test-cases were using relative
paths instead of the 'testDataDir' variable.

This commit fixes the remaining uses of relative paths, removes a
usage of QDir::setCurrent, and adapts QSslSocket to use TESTDATA.

f4436276d9 Skip a date-time test when we don't know what result it should give
The operator_eqeq(data13) test expected the local-time epoch and UTC
epoch to agree precisely if the localTimeType set by the test's
constructor says local time is UTC; however, when the local zone is
*sometimes* ahead of (or behind) UTC, due to DST, localTimeType is
duly set to indicate that, which doesn't preclude the zone agreeing
with UTC at the epoch.  This indeed happens for Europe/London, which
agrees on the epoch but was ahead a few months later.  So we can't
determine what outcome to expect based solely on localTimeType,
although we can be sure of a match when local time is UTC.  So skip
this test when local time isn't UTC (and document what's going on a
bit better).

a5c58d503d Revert "Adapt the QSsl* tests to use the resource system"
This reverts commit e1600c1a73.

The commit missed the fact that TESTDATA exists. Which supports
wildcards and then can automatically pick up new files when added (as
long as they match a wildcard) and then you don't need to maintain a
giant qrc file.

6ca48a847a Fix fallback fonts for non-common writing system
When we request fallback fonts, we cannot discriminate the fonts
based on the writing system support. This is especially important
since common script is now merged with other scripts, meaning that
a common script character will always go through the fallback
mechanism when not supported by the main font. When drawing
for instance a string of Devanagari characters on macOS, we would
get a list of 33 fallback fonts, but almost all of them would be
the default Devanagari font, since none of the other fallbacks
would support that script. Meaning that we would just check the
same font over and over, which makes no sense. The fallback list
has been retrieved specifically for the given script, so we do
not need to consider that when fetching the fonts.

For most of the common set, we will not have noticed the bug,
because at least one of the writing system-specific fallbacks will
have had support for latin characters as well. But when trying to
mix emojis and some non-common script, we would get a box in
place of the emoji, which had been adopted to the main script and
would only be looked for in the fonts supporting this.

Note that this exposed an issue with the QRawFont test on some
systems. When the sample text contained a space, it would
be possible to get a fallback font for this character, since
we now effectively support fallbacks. This is not the correct
behavior, but it is unrelated to this fix, and it was not what
the QRawFont::unsupportedWritingSystem() test was written to
check. I have therefore removed the space from the sample text
to make the test pass, and will make a separate task of fixing
the issue of merging fonts for whitespace characters.

[ChangeLog][QtGui][Text] Fixed a bug where mixing different
writing systems with emojis could lead to missing glyphs.

69496d4e22 Introduce QAbstractItemModel::checkIndex()
When implementing a custom model there's the habit, in each and every
function that takes a QModelIndex, to carefully checking the index
passed by the caller. This index is checked for "legality" (*): does the
index belong to this model, is the index pointing to an existing row and
column, and so on.  These checks are hand-rolled and, as such, slightly
different and possibly incomplete (i.e. wrong) every time.

What's worse, these checks are implemented via "ordinary" code (if
statements). However, passing an illegal index to a QAIM function is a
precondition violation, and as such does not (and must not) be
checked in ordinary conditions, as it triggers undefined behavior. On
the other hand, while debugging a custom model or a custom hierarchy
of (proxy) models, having such checks in place can be a significant
aid.

Enter checkIndex(): a debugging helper for QAbstractItemModel and its
subclasses. checkIndex() centralizes the checks for legality of a
given index. User code is free to assert on it, or have some other
fallback mechanism in case a check fails.

(*) Using "legality" here instead of "validity" in order to avoid
confusion between QModelIndex::isValid() and what checkIndex() really
does.

[ChangeLog][QtCore][QAbstractItemModel] Added
QAbstractItemModel::checkIndex(), a debugging function for
QAbstractItemModel subclasses.
