If gai_strerror() isn't available, use a macro that simply returns
a static error message (regardless of the real error code).
For example, GNU libc 2.0.7 doesn't implement gai_strerror().
This fixes the problem that ngIRCd can't do any IDENT lookups because
of the socket has already been closed in the child process.
The bug has been introduced starting with ngIRCd 17 ... :-(
(commit ID 6ebb31ab35)
- User mode "R": indicates that the nick name of this user is "registered".
This mode isn't handled by ngIRCd itself, but must be set and unset by
IRC services like Anope.
- Channel mode "R": only registered users (having the user mode "R" set)
are allowed to join this channel.
DEBUG_BUFFER is off by default and therefore disables these messages:
- "Handle_Write() called for connection XX, YY bytes pending ..."
- "Connection XX: ZZ bytes left in read buffer."
* ServerMode:
Handle channel user modes 'a', 'h', and 'q' from remote servers
Handle unknown channel modes on server links
Handle unknown user modes on server links
IRC_MODE(), Client_Mode(): code cleanup [2/2]
Enlarge client user mode buffer, reduce client flags buffer
Infom clients when other servers change their user modes
IRC_MODE(), Client_Mode(): code cleanup [1/2]
These channel user modes aren't used for anything at the moment, but
ngIRCd knows that these three modes are "channel user modes" and not
"channel modes", that is that these modes take an "nick name" argument.
Like unknown user and channel modes, these modes are saved and forwarded,
but ignored otherwise.
We have to enlage our user mode buffer, so we can handle even unknown
user modes in the future; and reduce the client flags buffer, because
I can't imagine why we ever would need ~100 flags!?
Now we support up to 15 user modes (was: 8) and up to 15 flags (was: 99).
So in the end, we even save 99-15+8-15=77 bytes for each client structure!
Use ps(1) flag "-a" (as well as "-f"):
"Select all processes except both session leaders (see getsid(2)) and
processes not associated with a terminal."
Thanks to Götz Hoffart for reporting this problem!
On server-links, spoofed prefixes can happen because of the asynchronous
nature of the IRC protocol. So don't break server-links, only log a message
and ignore the command.
This fixes bug 113, see:

Citing an email from Florian to the ngIRCd mailing list:
"I wonder what the expected behaviour is when Conf_MorePrivacy is changed
from 'yes' to 'no' and the config is reloaded.
At the moment, WHOWAS will start giving out information on Users that
were connected during Conf_MorePrivacy=yes period. If this is not
wanted, Client_RegisterWhowas() should be changed to not store a record
when Conf_MorePrivacy is enabled."
And I think it is "not wanted" :-)
For outgoing connections, we use 2048 (DH_BITS) since commit 49b2d0e.
This patch enables ngIRCd to accept incoming connections from other servers
and clients that use at least 1024 bits (and no longer requires 2048 for
incoming connections, too).
Patch proposed by Florian Westphal.
