* parser.c: removed some extern before function code reported by
  Kjartan Maraas on IRC
* legacy.c: fixed compiling when configuring out the HTML parser
* Makefile.am: added a declaration for CVS_EXTRA_DIST
* HTMLparser.c: beginning of an attempt at cleaning up the construction
  of the HTML parser data structures, current data generate a huge
  amount of ELF relocations at loading time.
