2fbe460245 QAndroidActivityResultReceiver: avoid double(triple)-lookup
The code used the if (!contains()) { insert() } anti-pattern,
necessitated by Qt's deviation from the STL of allowing insert() to
overwrite an existing entry, causing two lookups of the same key.

Fix by recording the size prior to the execution of the indexing
operator and taking a size increase as the cue to populate the (new)
entry. This way, we look up the key only once.

Also fix two instances of double lookup caused by the if (contains())
{ value() } anti-pattern.

07034b765e Use Authz API to query permissions info in Windows filesystem backend
Microsoft documentation for GetEffectiveRightsFromAclW function that
was used previously has this at the top of the page:

> GetEffectiveRightsFromAcl is available for use in the operating
> systems specified in the Requirements section. It may be altered
> or unavailable in subsequent versions. Instead, use the method
> demonstrated in the example below.

This says to me that the function is deprecated. In addition to
that, it is not able to handle ACLs that are not in "canonical"
order, returning ERROR_INVALID_ACL. Such ACLs are useful to
represent POSIX permissions in Windows, and are produced by
Cygwin for example.

This patch uses Authz API referenced by the message quoted above.
The used API is available starting from Windows XP/Windows Server
2003. This API also allowe to perform access checks given access
token, and so allows to use similar code all permission checks.

7fe5611365 QHash: optimize value(key) and key(value) callers
... by not injecting potentially-expensive temporary objects into the
caller's stack frame.

Default arguments are a convenient way to avoid overloads, but if the
defaulted argument isn't a Trivial Type, and the common use case is
not to pass the extra argument explicitly, the construction of the
temporary can dominate the call's runtime.

Since QHash is generic code, we don't know whether T or Key are
expensive or cheap to construct, so use overloading instead of default
arguments to avoid injecting needless code into call sites.

Changes][QHash/QMultiHash] The value(key) and key(value) functions are

argument) to avoid injecting temporary objects into the caller's stack

71faedc5b4 Fix deserializing Qt 5.x fonts through QDataStream
In Qt 5, fonts had both singular family and plural families properties,
and both were stored separately when streaming through QDataStream. The
families list was treated as an extension of family in this case, and
the primary font family was always the singular family property.

In Qt 6, it has been merged into one and family() is now just a
convenience for families().at(0).

But when reading files generated with Qt 5, we would ignore the fact
that these were previously separated. We would first read the family
entry into the families list, and then we would later overwrite this
with  an empty families list.

Instead, we detect streams created with Qt 5.15 or lower and make sure
we append the families list instead of overwriting it in this case. In
addition, we need to make sure we split up the list again when
outputting to Qt 5.x.

This adds a file generated with QDataStream in Qt 5.15 to the test to
verify.

[ChangeLog][Fonts] Fixed a problem deserializing the family of fonts
that had been serialized using QDataStream in Qt 5.

4bee9cdc0a macOS: Fix QSlider's knob positioning on Monterey
QMacStyle has a single NSSlider that is used to render any QSlider. For
each QStyle API operating on a slider, the style sets the slider up with
respecive properties. On macOS 12, the NSSlider maintains some states
that make QSlider instances influence each other's knob position when
rendering, resulting in uncontrollable jumping of the slider.

This can be fixed by not using startTrackingAt/stopTracking APIs, which
are however the only way we have to make the slider knob get rendered
pressed - there is no property in NSSlider(Cell), and none of the NSCell
attributes have any effect. So we need to use startTrackingAt, and work
around the side effect by reinitializing the NSSlider by calling
initWithFrame.

This fixes the positioning error, but also causes flickering of the knob
when dragging. To fix the flickering, we have to always call
startTrackingAt for a slider that is pressed, even for calls to
setupSlider that are made in QStyle APIs that are not drawing anything.

Also tried with no complete success (either positiong bug or flicker):
* call prepareForReuse on the NSView
* always call stopTracking on the NSSlider

can't allocate it at compile time. However, we can resize(SIGSTKSZ) a
QVarLengthArray that's probably big enough anyway. At the same time,
increase the compile-time size to 32k, to match what our Catch2
harness for the self-test uses.

771657e55f Test the return from sigaction()
If we fail to install our own action, the contents of oldact are noise
anyway, so we can't use them to decide anything; and, in any case, we
didn't replace the prior action, so have no duty to restore it.

In the process, restructure and comment the code to make it easier to
follow what's going on and why. Package a conditional in a lambda to
make the #if-ery less problematic. This should also make it easier to
hack any other complications into the condition, should they arise.

8926eb86c6 Fix formatting of dates before 1601 in MS system locale
The relevant MS system calls (say they) don't support date formatting
for years < 1601 (but apparently do in fact) and the year field of the
data structure is unsigned, so can't support years < 0. As a result,
the windows back-end for QSystemLocale failed for negative years.
So replace year < 1601 with a place-holder and substitute after
formatting.

Added new tests (based loosely on one in qtdeclarative that failed) to
verify that this actually works. These reveal that macOS also fails to
handle negative years; marked as expected failure there pending a fix.

8dea25d501 Add a note on the sign of daylight-saving offsets
Given that at least one zone has a negative offset (so that it's in
standard time for most of the year, including summer, and
daylight-saving time relatively briefly during winter), QTimeZone's
docs should explain what that means.

Base class dtors should be virtual and public or else protected and
non-virtual. This one was neither of these.

be undefined behavior.
