Add selected manual pages transcribed from the HTML documentation.
Those pages which have not been transcribed are referenced as
gracefully as possible.
There is no perfect section for the ntp_* files, which document
configuration options for the NTP suite, so I'm putting them in
the same section as the pages for the utilities themselves.
