Windows has a problem relating to cross-DLL variable relocations: they
are not supported. Since QMetaObject's link to the parent class is done
via a pointer, every QMetaObject in a DLL or in the EXE that derives
from a class from another DLL (such as QObject) will be dynamically
initialized.
This commit changes the meta object pointers in QMetaObject::d from raw
pointers to a wrapper class SuperData, which is almost entirely source-
compatible with the pointer itself. On all systems except for Windows
with Qt 6, it's binary compatible with the current implementation.
But for Windows with Qt 6, this commit will store both the raw pointer
and a pointer to a function that returns the QMetaObject, with one of
them non-null only. For all meta objects constructed by moc, we store
the function pointer, which allows the staticMetaObject to be statically
intialized. For dynamic meta objects (QMetaObjectBuilder, QtDBus, QtQml,
ActiveQt), we'll store the actual raw pointer.
[ChangeLog][QtCore][QMetaObject] Some internal members of the
QMetaObject class have changed types. Those members are not public API
and thus should not cause source incompatibilities.
The macro QT_NO_DATA_RELOCATION existed in Qt 4 but was called
Q_NO_DATA_RELOCATION and only applied to Symbian. It was removed in
commit 24a72c4efa ("qglobal: Remove
symbian specific features").

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.

moc now successfully parses enum values, that have been deprecated with
[[deprecated]]. This is valid c++17 and should be handled correctly.
By adding that functionality it is possible to parse Windows headers
which use this deprecation mechanism.
To make sure, that moc works correctly even on compilers that do not
support deprecated enum values yet, the auto test explicitly uses
[[deprecated]] enum values during moc run.

C preprocessors augment their standard list of include paths from the
environment: Unix preprocessors use $C_INCLUDE_PATH (for C) and
$CPLUS_INCLUDE_PATH (for C++), plus CPATH for both, whereas MSVC uses
the an environment variable simply called "INCLUDE". Handling this for
MSVC is particularly important because the VCVARSALL.BAT script sets the
necessary #include paths in the environment for important things.
Without that being parsed, moc won't find some #defines, like
WINAPI_DESKTOP_FAMILY.
[ChangeLog][moc] qmake and moc now cooperate to use the Visual Studio
environment variables (set by the VCVARSALL.BAT script) to find system
include files. A possible consequence is that moc parses application
headers slightly differently, depending on #if conditions that depended
on macros that previous versions had not seen #define'd. Implementers of
other buildsystems are advised to pass the --compiler-flavor=msvc option
to moc.

In order for moc to properly parse #ifdefs and family, we've had
QMAKE_COMPILER_DEFINES as a list of pre-defined macros from the
compiler. That list is woefully incomplete.
Instead, let's simply ask the compiler for the list. With GCC and
family, we use the -dM flag while preprocessing. With ICC on Windows,
the flag gains an extra "Q" but is otherwise the same. For MSVC, it
requires using some undocumented switches and parsing environment
variables (I've tested MSVC 2012, 2013 and 2015).
The new moc option is called --include to be similar to GCC's -include
option. It does more than just parse a list of pre-defined macros and
can be used to insert any sort of code that moc needs to parse prior to
the main file.
