ItemType is useful and faster than RTTI. Until now it was
implemented by a 16-bit member in the base class, plus
(potentially) all constructors having to hand a value
in at item construction type (of type SfxItemType) to
get that member set correctly.
This works, but there is no reliable way to guarantee
coverage, and there have already been cases with missing
SfxItemType - these fallback to '0' and thus all Items
with ItemType() == 0 are assumed equal and might be
static_cast'ed to the wrong classes. Note that I
identified *35* Items that had no correct ItemType
set/implemented actually. It also uses 16-bit per
incarnated Item at runtime.
I thought and realized now a more systematic approach
to do that with a pure virtual function at the Item
itself. That can also be secured by a clang compiler
plugin in the future to keep it working. It uses one
virtual function per derived class, no longer space
in incarnated Items. Also the constructors will get
more simple again.
But the main aspect is security - we cannot afford
Items potentially being held as equal if they are not.
Unfortunately C++ does not offer something like a
'strict pure virtual function' that would force to
be overloaded in every derivation, but the used
methotology and adding a clang test is reasonably
safe.
Have now done the cleanup of previous method.

The mechanism is currently broken because it uses hash values as keys,
in two different places. But hash values are not required to be unique,
and as soon as there are enough items of a given type, a collision is
inevitable.
So just simplify this whole mechanism. There is no reason we need
type-specific item managers. Stuff everything into a single global pool,
that uses hashing correctly.
Notes
(*) Performance, as far as I can tell, is the same or slightly better.
(*) I removed the NUMBER_OF_UNSHARED_INSTANCES thing, in favour
of just having a simpler mechanism

The issue of 362d4f0cd4e50111edfae9d30c90602c37ed65a2 "Explicitly mark
overriding destructors as 'virtual'" appears to no longer be a problem with
MSVC 2013.
(The little change in the rewriting code of compilerplugins/clang/override.cxx
was necessary to prevent an endless loop when adding "override" to
OOO_DLLPUBLIC_CHARTTOOLS virtual ~CloseableLifeTimeManager();
in chart2/source/inc/LifeTime.hxx, getting stuck in the leading
OOO_DLLPUBLIC_CHARTTOOLS macro. Can't remember what that
isAtEndOfImmediateMacroExpansion thing was originally necessary for, anyway.)

Specifically, otherwise my defaultvalue clang plugin would want to
remove lots of places that contains #define constants which, while
technically the same as the default value, convey semantic
