39daa368d4 Torrent example: Use QByteArray toPercentEncoding
The hand-rolled loop produced incorrect output and was subsequently
rejected by trackers.

The torrent example doesn't support modern features though, so it's
still a bit hit-or-miss whether a torrent will work. E.g. downloading an
Arch iso does not work since it relies on DHT, PeX and HTTP seeds.

aa37e67ef7 Port from qAsConst() to std::as_const()
We've been requiring C++17 since Qt 6.0, and our qAsConst use finally
starts to bother us (QTBUG-99313), so time to port away from it
now.

Since qAsConst has exactly the same semantics as std::as_const (down
to rvalue treatment, constexpr'ness and noexcept'ness), there's really
nothing more to it than a global search-and-replace, with manual
unstaging of the actual definition and documentation in dist/,
src/corelib/doc/ and src/corelib/global/.

dd562b3672 Replace qExchange with std::exchange
None of these users require C++20 constexpr or C++23 noexcept, the
only remaining difference between std::exchange and qExchange.

This leaves a single qExchange() user, in QScopedValueRollback, that
requires the constexpr version, only available from C++20, and thus
remains unported.

d97fd7af2b Build examples in isolated sub-builds using ExternalProject
Examples are intended to show how to build against an installed Qt.
Building them as part of the main build means the way the Qt targets
are defined and created are not representative of an end user's build.
By building them as separate projects using ExternalProject, we can
more closely replicate the intended audience's environment. This
should allow us to catch more problems earlier.

Having examples built as part of the main build also creates problems
with some static builds where a tool built by the main build is needed
during configure time. This happens with other repos like qtdeclarative
but not (currently) with qtbase. Converting the examples in qtbase to
be built using ExternalProject is intended as a demonstrator for how
other repos can do similar. Until other repos are converted, they will
continue to work as they did before, with examples as part of the main
build for non-static builds only.

The new build-externally behavior is only supported for non-prefix
builds with this change. Prefix builds will continue to use the old
non-external method. Support for building examples externally in
prefix builds will be a separate change.

0c51a87563 Fix CMake build of network/torrent example
The ui_XXX.h include did not match the location of the XXX.ui file, and
AUTOUIC failed with

    includes the uic file "ui_addtorrentform.h",
    but the user interface file "addtorrentform.ui"
    could not be found in the following directories
      "SRC:"

While this could be fixed by adjusting the include paths properly, this
would complicate the CMake project file, and we're dealing with an
example where needless complexity would cloud comprehensibility.

Move the .ui file next to corresponding source files instead.

This removes the need for any special cases in CMakeLists.txt, and we
can remove .prev_CMakeLists.txt.

Not much information in a bug report: QByteArray is protected from negative
sizes and QUdpSocket too. FWIW - add one more check, similar to what
the server counterpart already had.

Pick-to: 5.15 6.0

dfca01e186 Update the HTTP example
- Extended the documentation talking about it
- Initialize members in the header rather than in the ctor
- Some formatting changes
- Prefer connect-ing to QNetworkReply rather than QNAM for sslErrors
    - Because we didn't use the QNetworkReply* argument
- Put the QNetworkReply pointer in a managed pointer
- Removed the code explicitly handling a redirect (it's the new default)
- Edited HttpWindow::httpFinished so that there're less places to reset
    the reply pointer
- Updated some ifdefs I didn't update when I was revamping this example
