* New offapi com.sun.star.configuration entities to access the complete
  configuration read-only or read/write...
* ...configmgr adapted to support those new services/singletons...
* ...new unotools/configuration.hxx is the type-safe C++ plumbing on top of
  that...
* ...officecfg now generates C++ headers to access all the properties and sets
  given in the .xcs files...
* ...and svl's asiancfg.cxx exemplarily makes use of the new
  officecfg/Office/Common.hxx to access the configuration.
* There is still TODOs:  For one, see those listed in
  officecfg/registry/cppheader.xsl.  For another, at least a notification
  mechanism for the new read-only configuration access and the C++ wrapper is
  missing.
