* 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.
