  Improvements for old buffer compatibility
  
  Now tree.h exports LIBXML2_NEW_BUFFER macro indicating that the
  API uses the new buffers, important to keep code working with
  both versions.
  * tree.h buf.h: also export xmlBufContent(), xmlBufEnd(), and xmlBufUse()
            to help port the old code
  * buf.c: make sure the compatibility counters are updated on
            buffer usage, to keep proper working of application compiled
  	  against the old structures, but take care of int overflow
