Implement WEBIRC command
...
The WEBIRC command is used by some Web-to-IRC gateways to set the correct
user name and host name of users instead of their own.
Syntax: WEBIRC <password> <username> <hostname> <ip-address>
The <password> must be set using the new configuration variable "WebircPassword" in the [Global] section of ngircd.conf.
Please note that the <ip-address> is currently not used by ngIRCd (we don't store it in the CLIENT structure, only the resolved hostname).

conn.c: fix resolver server address backlog
...
if more than one ip address is returned for a single host
name, ngircd is supposed to try other addresses in case
connect() to the first address returned fails for some
reason.
Alexander Barton noticed that this did not work at all,
as the additional results were not stored.

enforce upper limit on maximum number of handled commands
...
reported on #ngircd: pasting lots of lines into a channel can kill off
many people on the channel if the read buffer is drained quickly enough
and the client-side TCP can't keep up with the incoming data.
This implements a throttling scheme:
- an irc client may send up to 3 commands per second before a one second
pause is enforced.
- an irc client may send up to 256 bytes per second before a one second
pause is enforced.
After discussion with Alexander Barton, server <-> server links are
treated specially: There is no artificial limit on the number of bytes
sent per second, and up to 10 commands are processed per second before
a pause is enforced.
It may be neccessary to make those limits tuneable to accomondate larger
networks, but for now they are compile time values.

conn.c: fix NumConnections imbalance

security: fix remotely triggerable crash in SSL/TLS code
...
When a server is running with SSL/TLS support compiled in,
it is trivial to crash the server by sending an MOTD request
via another server in the network.
- ONLY servers without ssl/tls support compiled in are not affected.
Disabling SSL in the configuration (no ssl listening ports, etc)
does NOT help.
- servers that are running standalone (i.e., not connected to any
other servers) are not affected, either.
This affects all ngircd releases since ngircd 13 (earlier versions
have no SSL/TLS support).

Connection counter: count outgoing connections as well.
...
This patch lets ngIRCd count outgoing connections as well as incoming
connections (up to now only outgoing connections have been counted). This
change is required because the Conn_Close() function doesn't know whether
it closes an outgoing connection or not and therefore would decrement the
counter below zero when an outgoing connection existed -- which would
trigger an assert() call ...
Please note that this patch changes the (so far undocumented but now fixed)
behaviour of the "MaxConnections" configuration option to account the sum
of the in- and outbound connections!

Allow mixed line terminations (CR+LF/CR/LF) in non-RFC-compliant mode
...
Up to now ngIRCd accepted CR+LF as well as a single CR or LF in "non RFC
compliant" mode (the default). But ngIRCd became confused when it received
data containing mixed line endings (e. g. "111\r222\n333\r\n").
This patch enables ngIRCd (in "non RFC compliant" mode) to detect CR+LF,
CR, and LF as equally good line termination sequences and to always end the
command after the first one detected.
Some clients (for exmaple Trilian) are that ... broken to send such mixed
line terminations ...
First patch proposed by Scott Perry <scperry@ucsd.edu>,
Thanks to Ali Shemiran <ashemira@ucsd.edu> for testing!

In addition, the "timeout" variable has been removed because it is

we don't have to double-check but better sleep. Pointed out by Florian.

If Listen is unset, it is treated as Listen="::,0.0.0.0".
Note: ListenIPv4 and ListenIPv6 options are still recognized,
but ngircd will print a warning if they are used in the config file.
Also, some plattforms require that ai_socktype
is set in the getaddrinfo() hints structure.
