fixing a leak detected by testapi in xmlDOMWrapAdoptNode, and fixing

* testapi.c tree.c: fixing a leak detected by testapi in
  xmlDOMWrapAdoptNode, and fixing another side effect in testapi
  seems to pass tests fine now.
* include/libxml/parser.h parser.c: xmlStopParser() is no more limited
  to push mode
* error.c: remove a warning
* runtest.c xmllint.c: avoid compilation errors if only some parts
  of the library are compiled in.
