* doc/apibuild.py doc/libxml2-api.xml doc/Makefile.am: new API
  building Python script, does the C parsing directly, generates
  a better API description including structure fieds defs and
  enums. Still a couple of bugs, but good enough for the python
  wrappers now.
* DOCBparser.c SAX.c nanohttp.c parser.c parserInternals.c tree.c
  valid.c xmlIO.c xmlmemory.c xmlreader.c xmlregexp.c xmlschemas.c
  include/libxml/schemasInternals.h include/libxml/tree.h: more
  cleanup based on the python analysis script reports.
* libxml.spec.in: make sure the API XML description is part of the
  devel package.
