'macOS' appears in the documentation frequently, and because it
resembles a variable/property name, QDoc links each occurrence
of it.
'WebChannel' appears as part of a module name, but it's also
a QML type - auto-linking each word to QML documentation is
confusing.
Likewise, there's no need to link 'OpenGL' each time.
Explicit links such as \l [QML] WebChannel continue to work.

A recurring problem with the Q_NAMESPACE macro is that it declares
an object (staticMetaObject) in the surrounding namespace. That
object lacks any export/import qualification to make it usable
with shared libraries.
Introduce therefore another macro to work around this issue, allowing
the user to prefix the object with an exporting macro, f.i. like this:
Q_NAMESPACE_EXPORT(Q_CORE_EXPORT)
The old macro can simply then be rewritten in terms of this new one,
supplying an empty export macro.
Note that NOT passing an argument to a macro expecting one is well
defined behavior in C99 -- the macro will expand an empty token.
Of course, MSVC doesn't like this and emits warnings. As a
workaround, use a variadic macro.
[ChangeLog][QtCore] Added the new Q_NAMESPACE_EXPORT macro. It
can be used just like Q_NAMESPACE to add meta-object information
to a namespace; however it also supports exporting of such
information from shared libraries.
[ChangeLog][Potentially Source-Incompatible Changes] Prefixing
Q_NAMESPACE with an export macro may no longer work. Use the new
Q_NAMESPACE_EXPORT macro for that use case.

CMake's moc file scanning is rather primitive: It will run moc on any
file containing a line that starts with Q_OBJECT (and similar macros).
We have four files in QtBase that contain such a macro at the start
of the line in a qdoc comment. These four files were excluded from
automatic moc handling by cmake, which is not ideal, since this will
silently fail when somebody actually adds a Q_OBJECT macro in code.
This patch introduces a macro Q_OBJECT for qdoc. This macro will be
replaced with Q_OBJECT in the generated documentation. While not nice,
at least a failure to use \Q_OBJECT is noticeable: Moc will warn about
the file.

Commit c5db8fc74 changed all instances of Q_WS_FOO to have the prefix
Q_DEAD_CODE_FROM_QT4 instead, to make it clearer when reading the code
that the code in question was a left-over from Qt4, when we used
Q_WS_ defines instead of Q_OS_ defines.
This worked well for cases of #ifdef Q_DEAD_CODE_FROM_QT4, but less so
for cases of #ifndef Q_DEAD_CODE_FROM_QT4, where the code was actually
unconditionally included.
To make this even clearer, the defines have been replaced by checks for
1 or 0, with a comment describing how the code used to look in Qt4. The
use of constants in the check also makes it easier for editors to parse
the condition and show visually that the code is defined out.
