[9fans] new links binary+source

[mirtchov@cpsc.ucalgary.ca]

New links binary + source -- Geoff Collyer's changes are in, which
means that links consumes much less cpu time.  Also rendering using
Plan 9 fonts is implemented -- right now Links renders only one size
using /lib/font/bit/lucm/unicode.9.font, which has an almost complete
unicode set.

There are provisions made for rendering in multiple size fonts,
however we need more complete font descriptions to be able to cover
the full gamma of possibilities.  Alternatively one can finally sit
down and write an autogenerating font file server using, for example,
ttf2subf.

If you have cyberbit you may want to experiment with it, but know that
html_gr.c sets the default font height to 17, which is what
unicode.9.font has.

You will find that rendering with Plan 9 fonts makes the browser much,
much faster and more responsive.  Scrolling/panning also become
useful, all of a sudden.

Beware -- the new event handling code causes the browser to crash if
resized while new york times is loading.  It came with Geoff's
changes, but I haven't been able to pin it down.

The source size has been significantly decreased because we don't
carry the precompiled fonts Links used to have (font_data.c and
fontdata).  The binary is only 700K gzipped and 3.2MB gunzipped.  The
code weighs in at ~2MB gzipped.

New screenshots also available, including rendering of japanese web
pages with kanji fonts.

Overall a significant improvement. It even seems usable sometimes.
