Pull up following revision(s) (requested by sevan in ticket #574):
share/man/man7/sysctl.7: revision 1.121,1.122,1.124 (via patch)

kern.module.verbose is a boolean, not an integer.  We had it right in the
text following the table, but the table itself was wrong.
Thanks to martin@ for pointing this out.

Sort ddb section in alphabetical order.

Bump date.
Improve description of ddb.commandonenter.
