makemandb(8), man(1) already use -C as an option to take man.conf path,
so use the same option for whatis(1) and apropos(1) for consitency.
apropos was using -C/-c to disable/enable context of the search
matches, change that to -M/-m respectively.
- Don't ever page unless asked for with -p
- Introduce "legacy mode" (-l)
1. searches only name and name_desc, prints name(section) - name_description
2. turns off escape formatting (can be forced on with -i)
3. turns off context printing (can be forced on with -c)
- Parse the environment $APROPOS variable as an argument vector.
With these changes one can simply 'export APROPOS=-l' and get the old apropos
behavior.
the path from the _mandb variable from man.conf now.
Set _mandb in man.conf to same value as was used before.

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.
