The original code lead to invoking a pure virtual function in Calc when
doing Ctrl-F2, ESC.

This reverts commit 9a11bd42.
Removing attributes from the _source_ node in SwTxtNode::MakeCopy does
not make any sens at all, and the cited issue i#96092 was apparently
fixed independently in CWS sw31bf04 by the change to ndtxt.cxx in
1524aa18.

Using XMultiPropertySet reduces the number of SwTxtNodes created for the
bugdoc from rhbz#789022 from ~5k to ~3k.

SwNodes::UpdateOutlineNode will add/remove the node from
SwNodes::pOutlineNds depending on IsOutline(), while various SwNodes
methods that move and delete nodes check GetAttrOutlineLevel() != 0,
which may be false even if IsOutline() is true.

Also the running of grep inside the test for GUI = WIN was a bit weird,
what was it supposed to grep? Standard input?

Start with the first service needed when running sc's filters_test:
the UniversalContentBroker. It might not be typical as ucb uses the
deprecated XSingleServiceFactory.

This commit is not at all a complete solution, far from it, just an
initial hack. Naturally once I come up with some generic enough way to
do the static linking the necessary macros etc will be added to some
general header.

The macro XSERVICEINFO_IMPL_1 (local to ucbhelper and ucb) is amended
so that it in the disable-dynamic-linking case also emits a function
whose assembler name equal contains the service name. This function
returns the XSingleServiceFactory for the service. Where the service
is instantiated we link directly to that function.

But probably this will be reworked a couple of times... Maybe it would
be better to simply have the service name specific entry point be a
pointer to the component's component_getFactory() function? Those all
have the same prototype.
