Implement whatis(1) as a special apropos(1) mode as a part of

the mandoc(1) binary; not yet enabled for the general public.
Intended to replace src/usr.bin/whatis at a later time.
Coded by kristaps@, with a few tweaks by me.

To test this:
 $ mandocdb  # unless you have already done so earlier
 $ sudo ln -s /usr/bin/mandoc /usr/bin/whatis.m
 $ whatis.m mandoc apropos whatis
 $ whatis.m man
