[rbldnsd] Announce: rbldnsd-0.83p1

[Michael Tokarev]

Prerelease of 0.83.  Highlights:

  - access control and filtering logging by IP

  - inlined qsort routine, speed up loading significantly.

  - removed some cruft from the code

Both access control and logging filtering are done using
network range lists (with optional negation via !), e.g.

  -a !127.0.0.2,127.0.0.0/8
   disallows (or does not log for -L) requests from 127.0.0.2,
   allows rest of loopback network
   disallows for anything else (implicit)

  -a localhost
  -a localhost/8
    allows access from localhost or loopback network,
    implicitly disallows anything else

  -a 10.8.1/16,!10/8
    allows access from 10.8.1.0/16,
    disallows access from rest of 10/8,
    implicitly allows anything else.

Also, log now includes timestamps.  Woops - I just forgot
about that...

If all goes right, and if netlist syntax is useful (hint: comments,
please! ;), I'll release this code as 0.83.
