DNSSEC patch for BIND

Attached is a patch that *should* enable DNSSEC support in BIND and all
related tools (e.g. dig). According to what I could find out looking at
the
original tarball release from ISC, defining OPENSSL and liking to
libcrypto
should be sufficient, but unfortunatley I have to little knowledge about
DNSSEC that I can actually set up a test environment to check if it is
really working. Maybe someone can jump in here.


Ok, I managed to set up an authoritive BIND server with a signed zone 
for my local network and a forwareder on a second machine following 
http://www.nlnetlabs.nl/publications/dnssec_howto/index.html.

The output from a query is attached at the bottom.
As I was doing many mistakes during the setup that ended up in error 
messages like "DS: authvalidated: got no valid KEY", "SERVFAIL" and 
"ignoring trusted key for 'xx.xx': no crypto support" and I finally got 
it working, I am 99% sure that dnssec is enabled correctly by this patch.

I am going to commit the patch in the next few hours.
