mandoc: Logically, the following are are type names - just like .Vt,

[schwarze]

Log Message:
-----------
Logically, the following are are type names - just like .Vt, 
some of them with an optional variable name following:
- .Ft
- .Fa in the SYNOPSIS
- .Fn second and later arguments in the SYNOPSIS
So add these to the .Vt macro table in the mandoc.db(5) database.
During my LibreSSL work, i'm getting really tired of typing
$ man -k Vt,Ft,Fa=some_type_name
over and over again; now, this becomes just:
$ man -k Vt=some_type_name
