The double-swap technique I used was flawed and broke on
self-assignment. What I had meant to use was the move-and-swap
technique. Thanks to Peppe for pointing it out.
This also fixes a compiler bug in the Green Hills compiler. It was
finding the wrong "swap" function in qSwap:
using std::swap;
swap(value1, value2);
It's supposed to find swap(QCborValue &, QCborValue &) due to argument-
dependent lookup. It's instead finding std::swap<QCborValue>, which
recurses.

Similar to the QJsonObject issue of the previous commit (found with the
same tests, but not the same root cause). One fix was that copying of
byte data from the QByteArray to itself won't work if the array
reallocates. The second was that
assign(*that, other.concrete());
fails to set other.d to null after moving. By calling the operator=, we
get the proper sequence of events.
[ChangeLog][QtCore][QCborMap] Fixed some issues relating to assigning

A simple 16k file can produce deep enough recursion in Qt to cause stack
overflow. So prevent that.
I tested 4096 recursions just fine on my Linux system (8 MB stack), but
decided 1024 was sufficient, as this code will also be run on embedded
systems that could have smaller stacks.
[ChangeLog][QtCore][QCborValue] fromCbor() now limits decoding to at
most 1024 nested maps, arrays, and tags to prevent stack overflows. This
should be sufficient for most uses of CBOR. An API to limit further or
to relax the limit will be provided in 5.15. Meanwhile, if decoding more
is required, QCborStreamReader can be used (note that each level of map
and array allocates memory).

QDateTimeEdit very aggressively prevents user input that would result in
values that are outside the dateTimeRange. While keyboardTracking is on
this makes sense, as otherwise the dateTimeChanged signal would be
emitted after each section, with a value that is outside the range.
However, this prevented users from entering a date that is allowed, but
where sections of the date are above or below the respective section in
the maximum or minimum value.
If keyboardTracking is off, QDateTimeEdit only emits the dateTimeChanged
signal at the end of editing, when focus is lost or the return key is
pressed, and then it enforces that the value is within the range anyway.
This change makes the parser ignore the range during editing if
keyboardTracking is off, thus allowing the user to enter a date where
temporary values are outside the range.
The test makes sure that we don't get signals emitted with out-of-range
values, testing both with and without keyboard tracking.

Constantly re-reading the timezone information only to be told the exact

a lot of QTimeZone creation, for example, V4's DateObject - which
creates them a lot (in DaylightSavingTA).
This performance problem was identified when I noticed that a
QDateTime binding updated once per frame was causing >100% CPU usage
(on a desktop!) thanks to a QtQuickControls 1 Calendar (which has a
number of bindings to the date's properties like getMonth() and so
on).
The newly added tst_QTimeZone::systemTimeZone benchmark gets a ~90%
decrease in instruction count:
--- before
+++ after
PASS : tst_QTimeZone::systemTimeZone()
RESULT : tst_QTimeZone::systemTimeZone():
- 0.024 msecs per iteration (total: 51, iterations: 2048)
+ 0.0036 msecs per iteration (total: 59, iterations: 16384)
Also impacted (over in QDateTime) is
tst_QDateTime::setMSecsSinceEpochTz(). The results here are - on the
surface - less impressive (~0.17% drop), however, it isn't even
creating QTimeZone on a hot path to begin with, so a large drop would
have been a surprise.
Added several further benchmarks to cover non-system zones and
traverse transitions.
