there is no more makewhatis

Import the new apropos/whatis.

This code has been developed by Abhinav Upadhyay as part of Google's Summer
of Code 2011. It uses libmandoc to parse man pages and builds a Full
Text Index in a SQLite database. The combination of indexing the full
manual page, filtering out stop words and ranking individual matches
based on the section gives a much improved user experience.

The old makewhatis and friends are kept under MKMAKEMANDB=no for now.
