Large sync between my W3C base and Gnome's one:

- parser.[ch]: added xmlGetFeaturesList() xmlGetFeature() and xmlAddFeature()
- tree.[ch]: added xmlAddChildList()
- xmllint.c: MAP_FAILED macro test
- parser.h: added xmlParseCtxtExternalEntity()
- valid.c: applied bug fixes removed warning
- tree.c: added CDATA block to elements content
- testSAX.c: cleanup of output
- testHTML.c: added SAX testing
- encoding.c: better error recovery
- SAX.c, parser.c: fixed one of the external entity processing of the OASis testsuite
- Makefile.am: added HTML SAX regression tests
- configure.in: bumped to 2.2.2
