As it stands, opposite_lane is only defined in terms of 'other traffic',
which itself only makes sense for oneway=yes. The current tagging scheme
is lame and inexpressive and we should fix it.

We'll probably have to introduce a new tag to say on which side of the
road the cycle lane(s) lie, relative to the direction of the way's
arrow. What about adding something like:

   cycleway:left=<any value permissible for cycleway>
   cycleway:right=<any permissible value for cycleway>

and stating explicitly that the existing cycleway=* definition still
means both sides: cycleway=FOO would imply both cycleway:left=FOO and
cycleway:right=FOO.

Suggestions of different things to use in place of :left and :right
would be very welcome. I'd suggest keeping it defined in terms that
allow rendering without foreknowledge of which side of the road one
cycles/drives in a particular country.

... also, let's bump up something like cycleway=share_busway too (from
tagwatch), because that's a common enough situation round here. Are
there any other popular, interesting tags from

   http://tagwatch.stoecker.eu/Europe/En/keystats_cycleway.html

that we should be thinking about?
