c24375a7de whois(1): Fix potential double-close and logic mistakes
Close the fd the poll error was detected on, rather than the last opened fd, to
fix the double-close.

Use -1 to make it explict which int variables no longer own socket file
descriptors.

Actually shrink, rather than grow, the poll timeout to match comment.

68c47fcfad whois(1): Pull out async multiple host connection code into a routine
This logic was added to the whois() function in r281959, but could easily be
its own routine.  In this case, I think the abstraction makes both functions
easier to reason about.

This precedes some Coverity-suggested cleanup.

c37dc1fb0b Example RIPE whois query with options and spaces.
Since it is used in the example, mention the -- option in the synopsis
even though it is a universal standard, and tweak to fit it on one line.

42e88fe650 Handle whois referrals between RIRs
This is rather ugly, because the RIPE and APNIC whois servers do
not provide referrals for address blocks that they do not manage.
However ARIN is usually the right place or knows the right place
so we try there.

The particular instance which clued me in to this bug is U.Mich.
141.211.0.0/16 for which the referral chain should be IANA ->
RIPE -> ARIN. RIPE's RDAP does provide useful redirects (for
example try `curl -I http://rdap.db.ripe.net/ip/141.211.0.0)
so maybe their whois server can be improved.

AfriNIC's whois server gives more direct referrals, but they are
designed to be human-readable. Ugly, but we can manage.

The issue of referrals between RIRs is likely to become more important
in the future whith the increasing number of cross-region IP address
block transfers increases.

8efb5aa133 Fix whois queries for ARIN AS numbers.
The ARIN whois server likes AS number queries to be in the form
"a 8075" rather than "as7085".

f537d420bf Fix a regression in the .de and .dk whois special cases
Ensure the special cases trigger whether we come via a referral
or via the -c option. Match host names case-insensitively.

Use the default character set supported by .de (UTF-8) since that
is more compatible with the modern world than ISO 8859-1. Persuade
them to give us a useful answer whether an internationalized
domain name is given in UTF-8 or in punycode.

6f4d88df9f A lot of the cleverness in whois is no longer needed!
The IANA whois server has the right referral information for domain
names, IP addresses, and AS numbers, so whois does not need to be
able to choose servers itself (except for a few cases where referrals
do not work). We can delete a chunk of code, which is always fun.

This change improves the referral handling to be less sensitive to
all the various formats, and to allow multi-hop referral chains,
such as IANA -> registry -> registrar.

ARIN queries have the "+" flag added if no flags are present, so we
get full details if the query matches multiple objects. The Verisign
anti-spam logic is also now suppressed if the user provided a non-
trivial query string.

Uninformative rubric is now trimmed by default. The -S option
turns off trimming, and disables query fettling.

The -i option is back to its traditional pre-1999 hostname, since
whois.internic.net is more useful than whois.networksolutions.com.
Note that the old fallback/default server whois.crsnic.net is an
alias for whois.internic.net.

The manual is more informative about query syntax.

9242719ed3 Although the website [1] says US-ASCII is accepted, ISO-8859-1 seems to
be the only accepted character that is close enough to US-ASCII (and
this is also done on OpenBSD; the alternative would be to use UTF-8).

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

c343f06104 whois: special case certain query suffixes
This extends the existing support for -NORID handles
to include -NICAT, -ARIN, and -RIPE 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.

3cddd28ef1 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.
