6bd35bf090 Implement RFC 2812 handling of "0" argument to JOIN 
The students in my software-engineering class are writing IRC clients in
Java, and I'm running ngIRCd as a sandbox for them to play in. We
noticed ngIRCd doesn't obey the "JOIN 0" command specified in RFC 2812:

   JOIN 0             ; Leave all currently joined
                      channels.

http://tools.ietf.org/html/rfc2812#section-3.2.1
I believe the following patch addresses this. Cheers!

[fw@strlen.de: put it into a seperate function]

3022d7cff3 Don't use Client_Type after command has been processed. 
This caused a read from already free'd memory, if the processed
command (IRC_QUIT) calls Client_Destroy.

4add9c29ed [Parser]: Fix minor sparse warnings 
parse.c:56:9: warning: symbol 'My_Commands' was not declared. Should it be static?
parse.c:107:9: warning: symbol 'My_Numerics' was not declared. Should it be static?

Also move handling of numerics into a seperate helper function.

47a0379e2b remove ip-string from Conf_Server struct 
struct Conf_Server stored the ip address to connect to
in dotted-decimal notation; but we only need this for connect()
so long-time storage isn't necessary.

82d32ffb28 bind ListenAddress for outgoing connections 
ngircd would always use INADDR_ANY for outgoing connections;
which might not be desirable. Added new [Server] option
"Bind" to set source ip.

47ca178a21 Introduce option to configure the maximum nick name lenth in ngircd.conf 
- New configuration option "MaxNickLength" to specify the allowed maximum
  length of user nick names. Note: must be unique in an IRC network!
- Enhanced the IRC+ protocol to support an enhanced "server handshake" and
  enable server to recognice numeric 005 (ISUPPORT) and 376 (ENDOFMOTD).
  See doc/Protocol.txt for details.

ad7361dfe0 if ngircd doesn't run chrooted, it tries to chdir 
to the users working directory (as returned by getpwuid()).
Failing to chdir to that directory isn't an error; so
log with LOG_INFO and prefix the message with "Notice".
