[svn] A bunch of new features:

- use mmap() to read whole files in core instead of allocating memory
  and read'ing it.

- use a new, more general, HTML parser (html-parse.c) and interface to
  it from Wget (html-url.c).

- respect <meta name=robots content=nofollow> (easy with the new HTML
  parser).

- use hash tables instead of linked lists in places where the lists
  were used to facilitate mappings.

- rewrite the code in host.c to be more readable and faster (hash
  tables instead of home-grown lists.)

- make convert_links properly convert partial URLs to complete ones
  for those URLs that have *not* been downloaded.

- use HTTP persistent connections where available.  very
  simple-minded, caches the last connection to the server.
