Provide new xmlBuf based saving functions

Browse Source 
* include/libxml/tree.h: adds xmlBufGetNodeContent and xmlBufNodeDump
  as xmlBuf based equivalents of xmlNodeGetContent and xmlNodeDump
* tree.c: implements one new routine and converts xmlNodeBufGetContent
  to use the xmlBuf equivalent. It should behave better as a result
  in case of data larger than 2GB.
