Time to commit 3 days of work rewriting the parser internal,

fixing bugs and migrating to SAX2 interface by default. There
is some work letf TODO, like namespace validation and attributes
normalization (this break C14N right now)
* Makefile.am: fixed the test rules
* include/libxml/SAX2.h include/libxml/parser.h
  include/libxml/parserInternals.h SAX2.c parser.c
  parserInternals.c: changing the parser, migrating to SAX2,
  adding new interface to switch back to SAX1 or initialize a
  SAX block for v1 or v2. Most of the namespace work is done
  below SAX, as well as attribute defaulting
* globals.c: changed initialization of the default SAX handlers
* hash.c tree.c include/libxml/hash.h: added QName specific handling
* xmlIO.c: small fix
* xmllint.c testSAX.c: provide a --sax1 switch to test the old
  version code path
* result/p3p result/p3p.sax result/noent/p3p test/p3p: the new code
  pointed out a typo in a very old test namespace
