added a new configure option --with-push, some cleanups, chased code size

* HTMLparser.c Makefile.am configure.in legacy.c parser.c
  parserInternals.c testHTML.c xmllint.c include/libxml/HTMLparser.h
  include/libxml/parser.h include/libxml/parserInternals.h
  include/libxml/xmlversion.h.in: added a new configure
  option --with-push, some cleanups, chased code size anomalies.
  Now a library configured --with-minimum is around 150KB,
  sounds good enough.
