Fix DirectShow COM class hierarchy
Remove the class DirectShowObject. Move the ref counting code
to a macro COM_REF_MIXIN that is used for the classes that are
actually instantiated.
Fix warnings:
common/directshowpin.h(56,5): warning: 'reinterpret_cast' from class 'DirectShowPin *' to its base at non-zero offset 'IUnknown *' behaves differently from 'static_cast' [-Wreinterpret-base-class]
DIRECTSHOW_OBJECT
^~~~~~~~~~~~~~~~~
common/directshowobject.h(69,33): note: expanded from macro 'DIRECTSHOW_OBJECT'
return GetInterface(reinterpret_cast<IUnknown*>(this), ppv); \
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
common/directshowpin.h(56,5): note: use 'static_cast' to adjust the pointer correctly while upcasting
