The TraceLoggingValue template does not have overloads for Qt
types, so it was throwing multiple template instantiation errors
while trying to log the unknown types.
Fix it by serializing such types to QString using QDebug::toString,
and the logging this string.
Apart from that, fixes some other compiler errors on Windows build
with -trace enabled:
- implicit size_t to ULONG conversion
- complaints on std::min
- add QT_BEGIN_NAMESPACE/QT_END_NAMESPACE to the generated
*_tracepoints_p.h headers to fix the namespace build.

The tracegen tool was not taking into account that Qt could be build
with a custom namespace. As a result, the combination of namespace
build and tracing enabled was not working, because tracegen generated
classes without the namespace.
This patch fixes it.
We cannot add QT_BEGIN_NAMESPACE/QT_END_NAMESPACE because of the
tricky logic that recursively includes the generated header file
multiple times, also including the code like
static const struct lttng_event_desc *_TP_COMBINE_TOKENS(__event_desc___, TRACEPOINT_PROVIDER)[] = {
(hash)include TRACEPOINT_INCLUDE
NULL, /* Dummy, C99 forbids 0-len array. */
};
where TRACEPOINT_INCLUDE is the path to the generated header.
This patch is using QT_USE_NAMESPACE, wrapped into some #ifdefs.
This should be safe, considering that the generated trace headers
are only used as private API.
The windows tracing support seems to be broken even in a
non-namespace build, so it's not handled in this patch.

Using this macro avoids having to special-case code for when

Q_MOVABLE_TYPE was conceived before C++ had move semantics. Now, with

introduced as a synonym to Q_MOVABLE_TYPE. Usage of Q_MOVABLE_TYPE
is discouraged now. This patch replaces all usages of Q_MOVABLE_TYPE
by Q_RELOCATABLE_TYPE in QtBase. As the two are synonymous, this

This patch allows tools to be built for the target platform when the
QT_BUILD_TOOLS_WHEN_CROSSCOMPILING parameter is set at configuration
time.
To avoid naming conflicts, the target tools are suffixed with "_native".
The qt_get_tool_target_name() function can be used to get the tool name
for both scenarios (cross and non-cross compilation).
Extend pro2cmake to refer to the right target name for tools.
The relevant write_XXX functions have a new target_ref parameter that
will be "${target_name}" for tools and literally the target name for
everything else.

CMake will now generate config and target files for each module that
provides tools. As a result, namespaced global targets such as
Qt5::moc or Qt5::rcc can be made available.
Third party projects that require just these tools, and not the Qt
modules themselves, should specify CMAKE_PREFIX_PATH pointing to the
installed Qt location, and call find_package(Qt5CoreTools),
find_package(Qt5GuiTools), etc.
It is also possible to call
find_package(Qt5Tools REQUIRED Core Widgets) where the last option
is a list of modules whose tools should be imported.
Note that all the tools are in the Qt5::
namespace and not in the Qt5CoreTools:: or Qt5WidgetsTools::
namespace.
This commit also changes the behavior regarding when to build tools
while building Qt itself.
When cross compiling Qt (checked via CMAKE_CROSSCOMPILING) or when
-DQT_FORCE_FIND_TOOLS=TRUE is passed, tools added by add_qt_tool will
always be searched for and not built.
In this case the user has to specify the CMake variable QT_HOST_PATH
pointing to an installed host Qt location.
When not cross compiling, tools added by add_qt_tool are built from
source.
When building leaf modules (like qtsvg) that require some tool that was
built in qtbase (like moc), the module project should contain a
find_package(Qt5ToolsCore) call and specify an appropriate
CMAKE_PREFIX_PATH so that the tool package is found.
Note that because HOST_QT_TOOLS_DIRECTORY was replaced by QT_HOST_PATH,
the ensure syncqt code was changed to make it work properly with
both qtbase and qtsvg.
Here's a list of tools and their module associations:
qmake, moc, rcc, tracegen, qfloat16-tables, qlalr -> CoreTools
qvkgen -> GuiTools
uic -> WidgetTools
dbus related tools -> DBusTools

This patch fixes compilation with `-trace lttng` or `-trace etw`. We
need to forward declare QEvent, QImageReader etc., otherwise the types
will be unknown while compiling the trace points.
In order to handle this generically, the tracegen utility is extended
to support a 'prefix text' in the `*.tracepoints` input files. Any
text within curly braces will be embedded as-is in the generated file.
This can then be used to add forward declarations for the types we
need, including potential namespaces and such.
