If we sort the keywords once in the constructor, then we can do binary
search when looking up RTF keywords, and that speeds up the import by
about 20% using the first testcase from the bug.

I broke that when I added CB_CONTEXTUALSPACING

To fix the build. I can't test it on win32, thought it would work...

lcl_GetDefaultTextEncodingForRTF() in editeng did the same.

...that no longer uses XSimpleRegistry structures for the service data and thus
is potentially more performant.

* Registry-based functions from cppuhelper/bootstrap are deprecated now, client
  code should always use defaultBootstrap_InitialComponentContext.

* References to the obsolete UNO_WRITERDB have been removed.

* Some of the functions in cppuhelper/source that are used from multiple .cxx
  but had not been properly placed into .hxx have been cleaned up.

* css.lang.ServiceManager XSet insert/remove now support special
  sequence<NamedValue> to improve live deployment/removal of XML-based extension
  components data.

* 09524d41 "stoc: accelerate opening of multiple
  XML .rdb files in a directory" and its follow-up
  cb5c881a "avoid using the new rdb reading
  logic for empty/non-existent directories" have been obsoleted by this change
  and have been reverted again.

Also, add whole bunch of missing cases while at it.

The factor here is used to divide, so the parameters have to be
switched; this has always been broken but probably before
3ca2bef7 nothing called this.
This also reverts 7bf1fa37 because
that was a workaround for the problem in the wrong place.

Crashes on import of bugdoc from fdo#48969 with
 Assertion `n < this->size()' failed.
(regression from b35980d9)

CppunitTest_sc_databaserangeobj can fail with
'UcbContentProviderProxy::getContentProvider - No provider for ´com.sun.star.help.XMLHelp.'

added Application.DisplayExcel4Menus, Application.DisplayNoteIndicator, Application.ShowWindowsInTaskbar. Althought these attributes of the Application object don't do anything they allow setting and retrieval of the state. We could make a usable implementation for Application.DisplayNoteIndicator, the others though don't really seem to have any useful equivalent in the libreoffice world

looping vector iterators and push_back/erase don't mix well
