whois: add an option to query the PeeringDB

whois: alphabetize whois server list

whois: do not clobber command-line flags when tweaking O_NONBLOCK

This can make whois fail to follow referrals when it should.
The bug was introduced in r281959.

whois: try whois.nic.TLD if TLD.whois-servers.net does not exist

Based on an idea from OpenBSD.

whois: check WHOIS_SERVER as well as RA_SERVER environment variables

WHOIS_SERVER is used by Debian's whois client.

whois: code cleanup

Remove deprecated options.

Use pedantically correct types.

This extends the existing support for -NORID handles
to include -NICAT, -ARIN, and -RIPE handles.

This extends the existing support for -NORID handles

The suffix machinery is also used to work around a problem with
lack of referrals from the Nominet server for .uk: names under
.ac.uk need to be queried directly at JANET's whois server.

Try alternate addresses more agressively.

Attempt to connect to alternate addresses if the connect doesn't
succeed in 180ms, and cut wait time between connection attempts
in half for each additional, if no connection was established.

Take the first connection to succeed and close the others.

This makes whois more responsive when e.g. IPv6 service took long
time or fail to respond.
