un-macro some of display.h

Browse Source 
I recently captured preprocessor output for a file and the amount of
code being expanded--and subsequently compiled--for canspotmon() was
quite an eye opener.  This converts most of the macros it uses into
function calls.  The resulting executable generated for OSX (built
for x86_64 and containing four interfaces) is about 5.5% smaller! and
there wasn't any difference in speed that I could notice.

The knowninvisible() macro has been in error for as far back as the
git logs go (which include those for the second cvs repository, so
over 20 years now).
