2a80adc2f6 Network-chat example: Use QHash for peers
We don't key it on IP address anymore so we can drop
the use of QMultiHash.
This also requires moving the connections for error and disconnected
to readyForUse so we don't remove an active connection when a second
connection attempt happens from the same peer process.
But since we still need to deallocate those connection attempts
if they error out or simply disconnect, we connect their signals to the
QObject::deleteLater slot. In some cases we might call deleteLater twice
but that's fine.

226d06402b Network-chat: Fix remote peer making multiple connections
The system was just treating IP (and optionally port) as a unique
identifier, so if a peer had multiple possible paths to a client they
would connect multiple times.

This fixes that by generating using QUuid in each client.
We then use this during broadcast, replacing the username we
sent before (which was not used), and as part of the greeting.
The greeting now is more complex, since we need to send both
username and the ID.

804b26b77d Network chat: when removing an entry in multihash, specify which one
Using only the key means all clients with that IP address are removed.
But there could be multiple clients running on the same multi-user
system.
So, use the value as well to remove just the specific one.

This also fixes a bug where, when a client disconnects, all of the
connections are removed from the client's map, but only _one_ is removed
from the GUI.

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/.

efa9998521 Fix compiling of examples on Android
* Simplify add_qt_gui_executable() to not require WIN32/MACOSX_BUNDLE
  but provide it implicitly. It's redundant :)

* When on Android, build a module (shared library), just like qmake.
  This requires an additional library destination in the install() call,
  but that's ignored on other platforms.

* Fix typos in the android deployment generation settings function

* Use the correct cache variable to determine whether we're inside a Qt
  build or not. Right now this only works inside Qt builds anyway as
  QtPlatformAndroid.cmake is not publically accessible.

6732fa3a29 Fix linking of examples
Provide add_qt_gui_executable() as function in our public API that takes
care of automaticWinMain linkage. We can use this in the future to
encapsulate similarplatform-specific behavior and adjustments, such as
module generation onAndroid.

In order for the examples to see the function in Qt5CoreMacros, three more
additional fixes were required:

    * Do the build_repo_end() call _before_ attempting to build the
      examples, as we need the build_repo_end() to include QtPostProcess
      and complete the creation of all the target config files.
      Otherwise the find_package() calls in the examples see something
      incomplete.

    * Add more QT_NO_CREATE_TARGET guards

    * Always call find_dependency on the dependencies, regardless of the
      target creation mode. This way a find_package(Qt5 COMPONENTS
      Widgets) will still load Qt5CoreMacros.
