djbdns/io.py: handle BrokenPipeError in parse_logfile().
This avoids a (harmless) crash when the output of djbdns-logparse is
piped to a process (such as head/tail) that closes the pipe before
djbdns-logparse is done writing to it.

bin/djbdns-logparse: handle SIGINT (again).
I removed the KeyboardInterrupt handler from the original program and
have now put it back as an async handler for SIGINT. This is helpful
when the user accidentally starts the program with no arguments and it
just sits there until he hits Ctrl-C (which would previously have
shown a stack trace).

*/*: refactor into a driver program and a library.
Now there are a few separate modules in a "djbdns" package, and the
djbdns-logparse executable that makes use of them contains only what
the main() function used to.
Instead of using True/False to signal success after possibly using
print() to actually write the result, we not just return either the
processed string, or None.

bin/djbdns-logparse.py: move regex handling down a level.
It was a bit awkward to match a line against a regex, and then to have
to immediately pass that match object into a function that knows what
to do with it (to avoid duplicating work). Now the handle_tinydns_log()
and handle_dnscache_log() functions create the match object themselves,
and signal success or failure by returning a boolean.

bin/djbdns-logparse.py: add some newer type mappings.
I've added srv, naptr, dnskey, tlsa, https, and caa type mappings
based on what my own logs contain. Only SRV is actually supported by
tinydns. There are probably others in use today that will show up
eventually.
