SOSAW080: Added first bunch of basic changes to helpers

SOSAW080: Make SdrModel& prerequisite to SdrObjects

Added need for SdrModel& in constructors of SdrModel,
SdrPage, SdrView and SdrObjList. Builds, not finished.

SOSAW080: removed and replaced old SdrModel

Removed and replaced GetModel()/SetModel() in all using
classes (SdrObject, SdrPage, SdrView), added accessors
to new referenced SdrModel, adapted all accessing places.
Refactored/Extended ::Clone and ::operator== for these
classes to allow cloning objects to a target SdrModel.
Adapted places where this is done AFAP. Added quite some
comments (tagged with 'TTTT') where possible further work
is needed. Builds completely, thus checking in. This does
not mean that this change is done yet.

SOSAW080: Adapted SdrPage/SdrModel relationship

Also needed to work on copy-construction of SdrPage and hierarchy,
quite some stuff removed, no copy-constructor anymore, no
MigrateItemPool stuff. Builds well, test stuck, will need
some cleanup/finetunung

SOSAW080: Smaller corrections/includes adapted

SOSAW080: Smaller corrections/includes adapted

SOSAW080: Debugging/Stabilizing/MakeUnitTestWork

SOSAW080: Stabilized for UnitTests, cleanups

SOSAW080: Adapted GetObjGraphic to just take a const SdrObject&

SOSAW080: Removed ChangeModel from classes

Classes SvxTextEditSource and SvxDrawPage (including
TextEditSource stuff) do not need change of SdrModel
anymore.

SOSAW080: Adapted some comments to make more readable

SOSAW080: Corrected constructor

SOSAW080: getSdrModelFromUnoModel added override marks

SOSAW080: Added missing includes

SOSAW080: Corrected SdrPage constructor

SOSAW080: Corrected some SdrObject::Clone scenarios

Especially when cloning to another SdrModel and taking
the sdr::properties into account.

SOSAW080: Added include for Mac-Build

SOSAW080: Added Scale to DefaultProperties

If a SdrModel change happens in DefaultProperties copy
constructor (used from Clone()), potentially a Scale
for the SfxItems has to be done.

SOSAW080: Added missing include for MacBuild

SOSAW080: Corrected CppunitTest_sc_anchor_test

An adaption of a SdrPathObj instantiation was missing,
added that. Seems as if that test is no tpart of the
usual 'make' scenario, but used/executed in gerrit builds

SOSAW080: Reworked SvxShape to use SdrObject's SdrModel

SOSAW080: Reworked SvxShape to use SdrObject's SdrModel

SOSAW080: Free SdrObjects when SdrModel goes down

In an UNO API test problem is that SvxShapes reference
SdrShapes, but these are not added to a SdrPage and not
'owned' by the SvxShape. Thus these do not get deleted
at all (same in master, memory leak). I extended
SvxShape::Notify the case for ModelCleared to also
Free the SdrObject when not owner and it's not added to
a SdrPage (in that case it gets deleted with deleting
the SdrModel)

SOSAW080: Solve UNO API calls that move SvxShapes to other Model

Due to UNO API tests I got a call to insert an xShape to a
xDrawPage which was constructed in another Model, this has now to
be done by Cloning the SdrObject to the new SdrModel, getting
rid of the old one and getting all the UNO implementation
stuff right (referemces SdrObject <-> xShape).
