[rbldnsd] Pre-announce: rbldnsd-0.74pre1

[Michael Tokarev]

Mostly cosmetic changes, but some may be useful.
 From the changelog:

2003-03-29 0.74pre1

  - added exclusions to ip4vset and dnvset zones - entry starting with
    an exclamation sign `!' treated as _excluded_ from a set.  Useful to
    include large networks but exclude some hosts.

  - fixed potential memory leak when memory is unsufficient to extend an
    array of entries (may this even happen?), where erealloc() routine is
    used

  - added pidfile (-p) writing option.  Thanks to Bruce Gingery @gtcs.com.

  - reorganized source

  - use common routine to read zone data files, and handle long lines
    in zones more accurately

  - allow first line of zonedata to start with a comment, so default
    RR values may be specified in first _non-comment_ line.

If all will go right, I'll release this code as 0.74.

Note: other features, such as NS records support, are planned.
I want to release current code first - all the changes which was
made so far - before breaking stuff again.  And with other
record types support, new rbldnsd will be incompatible - it
will use config file or something similar, no more fancy command
line.
