Don't use isdigit() function any more, because it only checks the

Add [Features] section to ngircd-test{1|2}.conf
Fix commit 5a34bb203a:
It is not enough to strip the "No" prefix from "Ident" and "PAM",
but we have to introduce the new [Features] section to fix all
warning messages of ngIRCd.
Variables "Ident" and "PAM" in [Global] are completely wrong :-(
Channel_CheckAdminRights(): test if client can admin a channel
This generic function tests if a client is allowed to do administrative
tasks to a specific channel:
- servers and services are always truested ("allowed everything"),
- channel operators are allowed,
- IRC operarors are allowed if OperCanUseMode is set in the config.
libc should know better than us.
Also, this helps debugging with tools like valgrind:
When you allocate an array of size x, and then erronoulsy
use x+1 valgrind cannot detect the bug because due to ALIGN_()
made by array.c we might have allocated more than size x...
ngircd unfortunately uses several options using double-negation, e.g.
NoIdent = No, NoPam = No, etc.
This renames all options by dropping the "No" prefix, e.g.
"NoIdent = no" becomes "Ident = yes".
The old options will continue to work, but will cause a warning
message.
Also update man pages and default config.
To prevent silly
'Ident = yes' from appearing in --configtest output in the
'ident support not compiled in and Ident Option not used' case,
make default value depend on feature availability.
If feature is available, enable by default, otherwise disable.
We might consider moving these options to a new
[Feature]
section, or something like that, because none of these options are
essential.
Another possible improvement:
'Ident = yes' option in ngircd.conf causes a warning if ngircd was
built without ident support.
--configtest: remember if MOTD is configured by file or phrase
Configuration variables "MotdFile" and "MotdPhrase" are mutually
exclusive; so don't display content in both of them when running
"ngircd --configtest": instead remember which one is beeing used.
Remove "error file" when compiled with debug code enabled
The information written to the "error file" (/tmp/ngircd-<PID>.err) when
ngIRCd is compiled with debug code enabled isn't that usefule, so don't
create this file at all.
Fix up generation and distribution of sample-ngircd.conf
- Add generated sample-ngircd.conf to new .gitignore file,
- refactor Makefile.am to generate sample-ngircd.conf on "make all",
to clean it up on "make clean", and to install it to the correct place.
- Make sure path names in sample-ngircd.conf are separated by "/".

Fix connect attempts to further IP addresses of outgoing server links
If a hostname resolves to more than one IP address (round-robin DNS,
IPv4 and IPv6) and an attempt to connect to the first address fails,
ngIRCd should try to connect to the 2nd address, 3rd address etc.
But because of a wrong variable used in the call to New_Server(),
the wrong server structure has been used in further connection attemps
which possibly lead to connection attempts to already connected servers.

Debian: Install default /etc/pam.d/ngircd allowing all logins
This is required for backwards compatibility when installing the -full

present, so all login attempts would be denied ...
Creating /etc/pam.d/ngircd including "auth required pam_permit.so"
restores the old behaviour of allowing all connections.
disable pam_fail_delay() only is available starting with Mac
OS X 10.6; but we use the 10.5 SDK for campatibility, so don't use
this function at all when building using Xcode.

Generate ngIRCd version number from GIT tag
Now the ngIRCd release/version number is deduced from the "current"
annotated GIT tag; see "git describe --help" for details. This is the
same scheme the Linux kernel uses and gives much more details version
numbers for interim releases and inofficial source archives generated
using "make dist".
Please note: the version number is only updated it the autogen.sh
script is run; so after pulling in and pushing out new commits, you
should run ./autogen.sh!

Make sourcecode compatible with ansi2knr again
This allows to compile ngIRCd using a pre-ANSI K&R C compiler again:

K&R C compiler, but a few coding standards must be met.

Enable the daemon to dump its internal state in debug-mode.
This patch allows ngIRCd to dump its internal state (connected clients,
actual configuration) when compiled with --enable-debug. The daemon
catches two more signals:
- SIGUSR1: toggle debug mode (on/off),
- SIGUSR2: dump internal state to console/syslog.
Allows to defer/queue signal processing for execution on the next
event dispatch call, i.e. we can perform any signal action in
normal, non-signal context.
Example uses:
- Reload everything on HUP without writing a global "SIGHUP_received"
variable
- Dump status of internal Lists on SIGUSR1, etc.
Conn_SyncServerStruct(): test all connections; and work case insensitive
Fix synchronization of established connections and configured server
structures after a configuration update:
- Not only test servers that already have a connection, but also check

established (SERVER_WAIT state).
- And do the server name comparision case-insensitive.
Let CheckServers() not only skip servers that already have a
connection, but also skip servers to which a new connection is
already beeing established (SERVER_WAIT state).
