DHCPDv6 log messages

Description of problem:
logwatch's dhcpd module does not handle entries generated by ISC DHCPD for IPv6 addresses.

Version-Release number of selected component (if applicable):
logwatch-7.3.6-48.fc12.noarch
dhcp-4.1.0p1-13.fc12.i686

How reproducible:
100%

Steps to Reproduce:
1. Run "dhcpd -6" with appropriate configuration file.
2. Request dynamic IPv6 address.
3. Run logwatch.
  
Actual results:
All IPv6 related entries listed as Unknown Entries.

Expected results:
Normal table of DHCPD allocated addresses.

Additional info:
Message format seems to be slightly different for DHCPD IPv6 entries compared with IPv4 entries.

A sample of messages (not necessarily related to each other) is attached.

Add reporting on DHCPv6 log entries

Here is a patch that implements basic parsing of the DHCPv6 messages.  However at present there seems to be no method to tie leases back to who requested them, as for IPv6 the initial request is with temporary addresses, and the standard logging does not report what address is assigned!  In particular for static assignments you just have to trust it works!!

Updated reporting on DHCPv6 log entries

The previous patch was not detecting the run type correctly.  This has improved detection of the dhcpd start being IPv4 or IPv6, based on what address is bound to.
