In Citrix XenServer, the hosts have SSL private keys and certificates, but
those certificates are not signed by any certificate authority. So we
must provide a way to avoid checking certificates against a CA if we want
other OVS tools to be able to talk to XenServer hosts over SSL. This
commit makes that possible.
The ssl.man page uses the IQ macro, but doesn't define it. Usually this
doesn't matter since its already been defined by man page that's
including it. However, in a couple of cases it doesn't, so this cleans
that up.

In nroff manpages, a blank line adds vertical white space. When this is
followed by another command that also starts a new paragraph, the result
is a vertical skip twice as big as the normal inter-paragraph gap. The
solution is to use a line that contains just "." for white space within
the manpage, instead of a blank line. The resulting manpages look better.
