completely different fix for the recursion detection based on entity

* parser.c include/libxml/parser.h: completely different fix for
  the recursion detection based on entity density, big cleanups
  in the entity parsing code too
* result/*.sax*: the parser should not ask for used defined versions
  of the predefined entities
* testrecurse.c: automatic test for entity recursion checks
* Makefile.am: added testrecurse
* test/recurse/lol* test/recurse/good*: a first set of tests for
  the recursion
