qSwap() is a monster that looks for ADL overloads of swap() and also
detects the noexcept of the wrapped swap() function, so it should only
be used when the argument type is unknown. In the vast majority of
cases, the type is known to be efficiently std::swap()able or to have
a member-swap. Call either of these.
For the common case of pointer types, circumvent the expensive trait
checks on std::swap() by providing a hand-rolled qt_ptr_swap()
template, the advantage being that it can be unconditionally noexcept,
removing all type traits instantiations. Don't document it, otherwise
we'd be unable to pick it to 6.2.
Effects on Clang -ftime-trace of a PCH'ed libQt6Gui.so build:
before:
**** Template sets that took longest to instantiate:
[...]
27766 ms: qSwap<$> (9073 times, avg 3 ms)
[...]
2806 ms: std::swap<$> (1229 times, avg 2 ms)
(30572ms)
after:
**** Template sets that took longest to instantiate:
[...]
5047 ms: qSwap<$> (641 times, avg 7 ms)
[...]
3371 ms: std::swap<$> (1376 times, avg 2 ms)
[qt_ptr_swap<$> does not appear in the top 400, so < 905ms]
(< 9323ms)
As a drive-by, remove superfluous inline keywords and template
ornaments.

At the moment we have two main strategies for dealing with move
assignment in Qt:
1) move-and-swap, used by "containers" (in the broad sense): containers,
but also smart pointers and similar classes that can hold user-defined
types;
2) pure swap, used by containers that hold only memory (e.g. QString,
QByteArray, ...) as well as most implicitly shared datatypes.
Given the fact that a move assignment operator's code is just
boilerplate (whether it's move-and-swap or pure swap), provide two
_strictly internal_ macros to help write them, and apply the macros
across corelib and gui, porting away from the hand-rolled
implementations.
The rule of thumb when porting to the new macros is:
* Try to stick to the existing code behavior, unless broken
* if changing, then follow this checklist:
* if the class does not have a move constructor => pure swap
(but consider ADDING a move constructor, if possible!)
* if the class does have a move constructor, try to follow the
criteria above, namely:
* if the class holds only memory, pure swap;
* if the class may hold anything else but memory (file handles,
etc.), then move and swap.
Noteworthy details:
* some operators planned to be removed in Qt 6 were not ported;
* as drive-by, some move constructors were simplified to be using
qExchange(); others were outright broken and got fixed;
* some contained some more interesting code and were not touched.

The asymmetry is intentional: the getters can use toLatin1() because the
called functions, with a QUrl::FullyEncoded parameter, return ASCII
only. This gives a small performance improvement over the need to run
the UTF-8 encoder.
However, the data passed to setters could contain non-ASCII binary data,
in addition to the percent-encoded data. We can't use fromUtf8 because
it's binary and we can't use toPercentEncoded because it already encoded.

This class is meant to replace the QUrl functionality that handled
key-value pairs in the query part of an URL. We therefore split the
URL parsing code from the code dealing with the pairs: QUrl now only
needs to deal with one encoded string, without knowing what it is.
Since it doesn't know how to decode the query, QUrl also becomes
limited in what it can decode. Following the letter of the RFC,
queries will not encode "gen-delims" nor "sub-delims" nor the plus
sign (+), thus allowing the most common delimiters options to remain
unchanged.
QUrlQuery has some undefined behaviour when it comes to empty query
keys. It may drop them or keep them; it may merge them, etc.
