The -Winaccessible-base switch was added for GCC 10. Older GCCs had no
way to suppress the warnings, and the existing suppression of
-Winaccessible-base caused a warning of its own:
qcompilerdetection.h:1125:49: warning: unknown option after ‘#pragma GCC diagnostic’ kind [-Wpragmas]

Since GCC 8 and 9 are slowly fading away as supported compilers, the
simplest fix to get a clean build is to suppress all warnings for the
test on these compilers, by passing -w, as suggested by
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90449.
Short of moving the affected code into a separate header file and
applying `#pragma GCC system_header` to it, there appears to be no
other way to get rid of the warning.

The problem with non-legacy mode is that the backend uses the same
filename for the system semaphore file and for the shared memory file.
What happens is that when we try to call attach(), a semaphore is
created. Later in attach() we set unix_key, because ftok() returns
a valid handle (it uses the file which was created for semaphore).
After that, an attempt to actually attach to a shared memory fails, but
no clean-up is done.
So, a later call to create() sees that unix_key is already valid, but
it cannot properly clean it, because it does not actually refer to
any shared memory.
Fix it by cleaning up unix_key and nativeKeyFile if shmget() call in
attach() fails.

These special member functions have no purpose.
We never *documented* their semantics. Any code using them is
unconditionally wrong (which semantics was it assuming?), so we can
accept the SIC (type A). If a user needs such a copy, they would have to
reason on the intended semantics (relaxed? acquire/release?) and be
explicit in their code. Especially for assignment, they would need
understand the consequences of the memory ordering that apply on _each_
atomic object involved and not on the assignment operation as a whole
(there are no such semantics).
Testing this change on qtbase has already found bugs.
From a purely technical point of view: we don't guarantee lock-free
atomics nor we require them from the underlying platform. An atomic is
therefore allowed to be implemented as a mutex protecting a value, and
mutexes are not copiable. std::atomic follows the exactly same pattern
(not copiable nor copy-assignable) for exactly the same reasons, and Qt
atomics are implemented on top of std:: ones.
[ChangeLog][QtCore] The copy constructor and assignment operators of
Qt atomic classes (QAtomicInteger, QAtomicPointer) have been removed.
Their usage in user code should be considered a programming error, as no
memory ordering semantics were ever documented for these operations (and
therefore relying on any specific semantic would be relying on
undocumented, unportable behavior). This matches the API of the
std::atomic class in C++. Note that you can still use explicit
load/store operations to transfer a value across two Qt atomic objects,
and therefore use the memory ordering specified for the load/store
operations.

- Fix a narrowing conversion warning, qt_make_pollfd() takes an int
- Remove an unused include

When the array type is QJniObject or a subclass, then we need to
explicitly release the local reference returned by GetObjectArrayElement
in the QJniArray::at implementation. Do this by constructing the
QJniObject via fromLocalRef, which does exactly that.
Amends 80d4d55e25.
Add a test case that stresses the local reference pool, and fix the old
test case (which operates on a QJniArray<jobject>) to also release the
local references.

The format is changed from 6.7 to support more than UINT32_MAX - 1
elements. The format used to have a quint32 size. Now if the size is
larger or equal to 0xfffffffe (2^32 -2) the old size is an extend
value 0xfffffffe followed by one quint64 with the actual value. The
32 bit size with all bits set is still used as null value.

[ChangeLog][QtCore][QStringList] Added lastIndexOf() overloads that take
a QString/QStringView/QLatin1StringView and a Qt::CaseSenitivity
parameters. Prior to this calling lastIndexOf() would call the methods
inherited from the base class. This change is source compatible and
existing code should continue to work.

Now that users can pass a QStringMatcher to do the matching, change the
existing overload to not use QStringMatcher.
Thanks to Giuseppe D'Angelo for the idea of passing a QStringMatcher to
filter instead of using a magic number to decide whether to use
QStringMatcher or not.
Results of running filter() and filter_stringMatcher, times are in msecs

Drive-by change: optimize tst_QStringList::populateList().
[ChangeLog][QtCore][QStringList] Added filter(const QStringMatcher &)
overload, which may be faster for large lists and/or lists with very
long strings.
[ChangeLog][Possible Performance Changes][QtCore][QStringList] Changed
the implementation of filter(QStringView) overload to not use
QStringMatcher by default. Using QStringMatcher adds overhead, so it is
beneficial/faster when searching for a pattern in large lists and/or
lists with long strings, otherwise using plain string comparison is
faster. If using QStringMatcher makes a difference in your code, you can
use the newly added filter(QStringMatcher) overload.

Instead of the previous realpath() comparison resulting from the symlink
processing. parseMountInfo() was extracting the device number from
/proc, so this information was already readily available.
We must take care of anonymous block devices (major == 0). Certain
filesystems, such as btrfs, always use them, so we must still stat() the
device path to get the real block device.
This implementation assumes that udev only creates entries in the
/dev/disks/by-label directory that are symlinks to real devices, but
that must already be the case because they are in /dev in the first
place. An alternative implementation would be to compare the inode and
host device (st_dev) of the entry, if different /dev entries could have
different labels. I don't think that's possible. But multiple /dev
entries for the same device is definitely possible.
Pick-to: 6.6
