dircproxy

This Release Candidate 1 adds crash fixes and
documentation updates.

Binding to a local IP address is allowed. A new
"/dircproxy RELOAD" command was added to reload
the configuration. More DCC Resume support, OS X
support, and 005 support were added. SSL and IPv6
support are available as an experiment. A new
"/dircproxy NOTIFY" command and support for MD5
passwords in the configuration file were added.

DALnet recently changed the meaning of the +r user
mode: instead of indicating that your connection
has been restricted, it is now used to indiciate
that you have successfully registered with
NickServ. The old default action of dircproxy was
to disconnect from a server which set this mode,
and this has now been changed.

Zombie processes and core dumps which occurred while doing DNS lookups or
reloading the configuration file were fixed. An occasional problem where logs
from more than one connection class could get placed in the same directory was
fixed.

Signals are now handled in a more reentrant way to prevent any zombie/defunct processes. The DCC error messages were improved. There is a new logging infrastructure, the internal log directory name generation was fixed so that different connections' logs don't occasionally get merged, private messages are now internally logged and recalled separately, and for your own permanent copy they are logged in files named after the nickname rather than all together.
