Message : 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 Daniel svn path=/trunk/; revision=3783
