This change makes sure to resolve symlinks and copy only one file for
every dynamic shared library used (vs 3 before -> 2 symlinks + 1
actual library). This avoids duplicate files, as well as saves space
when creating wheel (e.g. no 3 copies of standalone WebEngine
library).
This filtering happens copying from CMake install dir into
pyside_package_dir (the symlinks are still present in the CMake
dir, but that shouldn't harm anybody, and might be useful for
users of shiboken only for example).

This change introduces a new type into the shiboken2 module which is
imported by calling "import PySide2.support.VoidPtr".
The type takes care of conversions from / to void* values in function
signatures.
Creating an instance can be done by passing either a shiboken wrapped
object, or an integer representing an address, or a python object that
implements the buffer interface.
For example, this is useful for passing numpy arrays to C OpenGL
functions that take void* parameters. First you convert the array into
a bytestring (using numpy.array.tobytes(), then you instantiate a
VoidPtr from that bytestring, and finally you pass it along to a GL
function.
One corner case that is currently not supported is void** parameters.

There's a lot of code that was previously used for doing conversions
between C++ / Python types (apparently relying on extensive
RTTI / typeid manipulations), which got superseded by a cleaner
templated approach.
The old code was left behind, and there were a few instances where it
was still used even though it wasn't needed, like in QtScript
typesystem XML and shiboken's enum handling.
Remove the old code, apply the small changes needed to make it work
with new the code.
This is cleanup to reduce the confusion regarding conversion
behavior, and also preparation for a proper implementation of handling
"void*" types.

For short the new features:
- there is a qApp in QtCore, QtGui and QtWidgets for compatibility,
and also in __builtins__ for a true macro-like experience.
- if you delete any qApp variable, the Q*Application is reset and you can
start over.
Long description:
There is a qApp macro in Qt5 which is equivalent to Q*Application.instance() .
Python does not have macros. Both PyQt5 and PySide2 have an
according structure in QtWidgets. In the case of PySide2, the qApp
variable is first initialized to None and later to QApplication().
This does not reflect the original sense of the qApp macro, because
- it only handles QApplication,
- it does not handle destruction.
This "macro" should live in QtCore, but both PyQt5 and PySide2 decided
to put this in QtWidgets. As a compromize, I propose to put qApp into
all three modules, and into __builtins__ as well, so wherever you
create an application, you find this "macro" in place.
While changing the code, I stumbled over the template
set_qapp_parent_for_orphan. I tried to make sense out of it and finally
removed it. There were no side effects but bug PYSIDE-85 is gone, now.
With some extra effort, I created a singleton qApp that changes itself.
This way, a true macro was simulated. Note that this was not possible
with a garbage collected variable, and I had to make shiboken aware of this.
As the final optimization, I turned qApp also into a fuse variable:
Delete any qApp variable and Q*Application will finish when there is
no extra reference.

The signature module was turned into a package under
'PySide2/support/signature'. The package is completely isolated
so that nothing is leaking into the normal import machinery.
The package is also not initialized unless a __signature__ attribute
is accessed. The only change to Python during a PySide run is
the existence of the __signature__ attribute.
As a side effect, all tests run at the same speed as before
this extension.
The module does not actively import PySide modules. Instead,
it inspects sys.modules and reloads its mapping.py if needed.
Example usage:
>>> PySide2.QtWidgets.QGraphicsAnchorLayout.addAnchors.__signature__
>>> PySide2.QtWidgets.QGraphicsAnchorLayout.__signature__
The module has been thoroughly tested on macOS.
I consider this ready.

check functions that return a converter function
for an array of matching size.
Add simple array converters for arrays of C++ primitive types.
Instances of the ArrayHandle<>, Array2Handle<> templates will be

This change decouples the naming of general shared libraries, python
module extensions, and cmake configuration files. All of them are now
computed depending on the python version and python build
configuration, and can also be manually set via CMake variables.
The module extensions names now use the most detailed 'import' prefix,
which usually informs whether a debug or release python was used, or
the Python ABI flags (for Python >= 3.2).
When a debug Python interpreter is used for building PySide2, the
preprocessor define Py_Debug is now correctly propagated to PySide2
sources, which fixes previous crashes in debug builds.
This affects only Linux and macOS builds. There is a subsequent change
for making it work for Windows builds.
All in all, this now allows proper mixing of debug / release versions
of the Python interpreter with debug / release versions of PySide2 on
Linux and macOS.
