add void to function decls with no args

Fix IPv6 link-local address handling for nameservers to talk to as
well as address to bind to.

We have sockaddr_storage these days, get rid of isc_sockaddr_t.
OK beck, "beautiful" deraadt

The various sockaddr structures have length fields these days.
OK beck

Mechanically replace isc_boolean_t with int.
OK deraadt

Bunch of dead stores and otherwise unused stuff lets us get rid of
unix/net.{c.h}. We need to sprinkle in a few #includes that net.h
dragged in.
OK deraadt

Rewrite isc_time_microdiff() as uelapsed() and put it directly
into dig sources, lets us get rid of unix/time.{c,h}
OK deraadt

Get rid of isc_parse_uint32() and replace it with strtonum.
While here use the standard strtonum error messages.

remove some uneeded includes

Get rid of ISC_MAGIC and ISC_MAGIC_VALID macros.
While pulling on that it turns out we can / need git rid of a isc_task
-> isc__task, isc_taskmgr -> isc__taskmgr, isc_timer -> isc__timer and
isc_socket -> isc__socket indirection.

+trace has the RD bit cleared however it asks the nameserver from
/etc/resolv.conf for a list of root name servers.
Arguably corectly configured recursive nameservers should REFUSE to
answer this question to prevent cache snooping.
Upstream fixed this after the license change by sending the first
query with RD set.
We go a different route, built in a list of root name servers and ask
them. Otherwise known as a priming query. This way +trace does not depend
on any localy configured nameserver in /etc/resolv.conf

Move dig(1) and needed DNS libraries into it's own source directory in
usr.bin/dig.

From the beginning when we started to remove unneeded nameserver code,
it was our goal to extract dig functionality from the bind sources,
for everyone's benefit as this is easier to reason about.

In total we removed about 2/3 or over 300.000 lines of code.

We kept the lib/ subdirectory layout but moved the content of bin/ to
the top from the old bind source directory.

Previous sources and history can be found in the src/usr.sbin/bind
Attic.
