Enable -Wnon-virtual-dtor for GCC 4.6

...which has the necessary features to support it.

Change a lot of classes to either contain a protected non-virtual dtor
(which is backwards compatible, so even works for cppumaker-generated
UNO headers) or a public virtual one.

cppuhelper/propertysetmixin.hxx still needs to disable the warning, as
the relevant class has a non-virtual dtor but friends, which would still
cause GCC to warn.

Includes a patch for libcmis, intended to be upstreamed.
