Log Message:
Pull up following revision(s) (requested by kim in ticket #1102):

        etc/ntp.conf: revision 1.21
        etc/ntp.conf: revision 1.22

Use "pool" for the pool.ntp.org servers. Add some new hints.
- Use the "pool" keyword for obtaining servers from ntp.pool.org.
  - Add "tos minclock" and "tos maxclock" to limit the number of servers.
  - Add "restrict source" to apply appropriate restrictions to servers.
    (Specifically "nopeer" cannot be applied to "pool" servers.)
  - A single "pool" entry suffices -- using "2.netbsd.pool.ntp.org" so
    that we get both IPv4 and IPv6 addresses. (No addresses are returned
    for just "netbsd.pool.ntp.org.")
- Add a comment about "tinker panic 0" -- useful for VMs and laptops.
- Add a comment about "discard minimum" -- useful for some SNTP clients.
- Add an explanation for the "limited" restriction keyword.
- Unify whitespace and comment formatting.

Add iburst to peer and server.
