QTimeLine appears to have very poor timing characteristics. Historical
CI logs show roughly one failure in every twenty-five test runs on
Windows, and less frequent failures on Mac and Linux.
The root of the problem seems to be that QTimeLine's currentTime
counter appears to run at a variable speed and the only guarantee is
that it is slower than wall time. The frameChanged() test
function waited for double the expected duration of the timeline and
still found that the timeline had failed to finish in about one in every
thirty test runs. The interpolation() test function also failed for the
same reason, though less often.
This commit makes the frameChanged test more strict so that the poor
timing will be demonstrated more often, waiting only 1.5 times the
duration instead of double the duration. It also makes the test fail
gracefully so that this known issue won't disrupt CI when the test is
made significant in a later commit.

QTimeLine::currentTime() is an integer in the range [0..duration], not a
float in the range [0.0..1.0]. The aim of the test appears to be to
verify that currentTime() is at least 90% of the way to duration() when
the timeline is almost due to finish, so verify that and give the
corresponding 10% tolerance on reaching the end state.

For example, a URL with no username is one where it's set to QString()

empty-but-present username, for which toString(RemovePassword) will
return "http://@kde.org", keeping the empty-but-present username.

By having the default value equal to zero, we follow the principle of
least surprise. For example, if we had
url.path()
and we refactored to
url.path(QUrl::DecodeSpaces)
Then instead of ensuring spaces are decoded, we make spaces the only
thing encoded (unicode, delimiters and reserved characters are
encoded).
Besides, modifying the default can only be used to encode something
that wasn't encoded previously, so having the enums as Encode makes
more sense.
As a side-effect, toEncoded() does not support any extra encoding
options.

But do not allow it in other parts of the URL. I could allow it in the

In order to do that, make DecodeReserved use two bits and have
PrettyDecoded set only one of them. That way, toString(PrettyDecoded)
can be distinguished from toString(PrettyDecoded | DecodeReserved),
just as path(PrettyDecoded) can be distinguished from
path(PrettyDecoded & ~DecodeDelimiters).
Also, take the opportunity to avoid decoding the reserved characters
in the query. Keep them encoded as they should be.

There's little value in having the DecodeUnambiguousDelimiters option
since neither QUrl nor QUrlQuery can return values that are ambiguous
in that particular context, ever.
This option could be used to encode a character if, when placed
in a URL, it would need to be encoded. Such cases are hash (#) or
question marks (?) in the path component, or slashes (/) and at signs
(@) in the userinfo.
However, we don't need two enums for that, since there are no
other characters that can appear in either form. Still, leave two bits
for this enum. In the future, if we want to split the gen-delims from
the sub-delims, we are able to.

Refactor the way that QUrl stores and returns the components of the
URL so that ambiguous delimiters (gen-delims that could change the
meaning of the parsing) are interpreted correctly. Previously, QUrl
called "unambiguous" the form found in a full URL, even though each
item in isolation could have more characters decoded.
Now, instead, store only the fully decoded form. To recreate the
compound forms (the full URL, as well as the user info and the
authority), we need to do more processing.
This commit applies to the user name, password, path and fragment
only. The scheme, host and port do not need this work because they are
special; the query is handled separately.

There were two constuctors offering essentially the same functionality.
One taking the QStatic*Data<N> struct, the other what essentially
amounts to a pointer wrapper of that struct. The former was dropped and
the latter untemplatized and kept, as that is the most generic and
widely applicable. The template parameter in the wrapper was not very
useful as it essentially duplicated information that already maintained
in the struct, and there were no consistency checks to ensure they were
in sync.
In this case, using a wrapper is preferred over the use of naked
pointers both as a way to make explicit the transfer of ownership as
well as to avoid unintended conversions. By using the reference count
(even if only by calling deref() in the destructor), QByteArray and
QString must own their Data pointers.
Const qualification was dropped from the member variable in these
wrappers as it causes some compilers to emit warnings on the lack of
constructors, and because it isn't needed there.
To otherwise reduce noise, QStatic*Data<N> gained a member function to
directly access the const_cast'ed naked pointer. This plays nicely with
the above constructor. Its use also allows us to do further changes in
the QStatic*Data structs with fewer changes in remaining code. The
function has an assert on isStatic(), to ensure it is not inadvertently
used with data that requires ref-count operations.
With this change, the need for the private constructor taking a naked
Q*Data pointer is obviated and that was dropped too.
In updating QStringBuilder's QConcatenable specializations I noticed
they were broken (using data, instead of data()), so a test was added to
avoid this happening again in the future.
An unnecessary ref-count increment in QByteArray::clear was also
dropped.

It is an extension coming from the use case when you, for instance, need to
implement a countdown timer in client codes, and manually maintain a dedicated
variable for counting down with the help of yet another Timer. There might be
other use cases as well. The returned value is meant to be in milliseconds, as
the method documentation says, since it is reasonable, and consistent with the
rest (ie. the interval accessor).
The elapsed time is already being tracked inside the event dispatcher, thus the
effort is only exposing that for all platforms supported according to the
desired timer identifier, and propagating up to the QTimer public API. It is
done by using the QTimerInfoList class in the glib and unix dispatchers, and the
WinTimeInfo struct for the windows dispatcher.
It might be a good idea to to establish a QWinTimerInfo
(qtimerinfo_win{_p.h,cpp}) in the future for resembling the interface for
windows with the glib/unix management so that it would be consistent. That would
mean abstracting out a base class (~interface) for the timer info classes.
Something like that QAbstractTimerInfo.

While QArrayDataPointer offers generic detach() functionality, this is
only useful for operations that may modify data, but don't otherwise
affect the container itself, such as non-const iteration, front() and
back().
For other modifying operations, users of the API typically need to
decide whether a detach is needed based on QArrayData's requirements
(is data mutable? is it currently shared?) and its own (do we have
spare capacity for growth?).
Now that data may be shared, static or otherwise immutable (e.g.,
fromRawData) it no longer suffices to check the ref-count for
isShared().
This commit adds needsDetach() which, from the point-of-view of
QArrayData(Pointer), answers the question: 'Can contained data and
associated metadata be changed?'.
This fixes QArrayDataPointer::setSharable for static data (e.g.,
Q_ARRAY_LITERAL), previously it only catered to shared_null.
SimpleVector is also fixed since it wasn't checking Mutability and it
