It implements missing man(7) macros used in base by kerberos/ntp and makes them
supported by mandoc.
This import should have been done before the removal of groff.

An important improvement has been made as well in makewhatis performance:
Tests on my laptop shows makewhatis on the entire system goes from 26s to 12s
- Compatiblity with existing manpages has been improved
- Now support ".so" directive with compressed manpages (which fixes a regression
we have since we have new man(1))
