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.
