nethack.rankin 175e5b67f5 accessible() ...

There's some discussion in the newsgroup about an engraving bug, and
while verifying that it's reproducible I've come across an unintentional
change between the current code and 3.4.3.  A recent change made engraving
use accessible(), and that routine wasn't yielding an appropriate value
when applied to a raised drawbridge if the terrain in front of it was ice
or floor (ie, moat or lava had been filled in).  Several places which used
the ACCESSIBLE() macro instead of the function suffer from same problem.

     This doesn't attempt to address the newsgroup bug (which is that an
engraving written on a lowered bridge transfers to the underlying terrain
if the bridge is raised, even when that terrain is water or lava; the
converse case applies too, an engraving on the ground gets transfered to
the bridge when it lowers).
