23b07bdf50 Allow channel admins to "de-admin" channel members
This patch fixes unsetting of channel user mode "+a" (channel admin)
and adds a better error message: without this patch, a channel admin is
unable to unset this mode.

This closes bug #142.

d21afce2b6 Allow user mode +x only when "CloakHostModeX" is set
Allow users to "cloak" their hostname only when the configuration
variable "CloakHostModeX" (introduced in 19.2) is set. Otherwise, only
IRC opertators, other servers, and services are allowed to set mode +x.

This prevents regular users from changing their hostmask to the name
of the IRC server itself, which confused quite a few people ;-)

This fixes bug #133.

192e304b94 Change build system to support new and old GNU automake
Starting with GNU automake 1.12, the "de-ANSI-fication support" has been
removed, which ngIRCd used to enable building itself on very old systems.

Now the problem is, that using automake >= 1.12 isn't working because of
the now unsupported M4 macros. Therefore the solution that this patch
implements is to dynamically generate the automake input files with our
own ./autogen.sh script:

  configure.ng => configure.in
  Makefile.ng => Makefile.am

This is quite an ugly approach, but it works and enables us to:

  1. use current automake >= 1.12 for development and "private builds",
  2. still build distribution archives using automake 1.11.x that have
     "de-ANSI-fication support" enabled in the generated Makefile's.

And if you are using Makefile's generated with a automake version newer
than 1.11.x (without "de-ANSI-fication support"), the ./configure script
warns you not to use this generated build system to generate distribution
archives.

Drawback of this patch: you MUST use our autogen.sh script, you can't call
the autoconf/automake commands directly any more; but autoreconf should
still work ...

bb20aeb9bc Initialize SSL when needed only, and disable SSL on errors
With this patch, the SSL subsystem will only be initialized if at least
one SSL ports is configured; so you won't get "SSL initialization failed"
messages if you didn't configured it at all.

And if SSL initialization fails, no SSL listen ports will be enabled
later which never could establish a working SSL connection at all ...

f38a9035e5 Show a warning on startup if config file is not a full path
ngIRCd is a long-running process and changes its working directory to "/" to
not block mounted filesystems and the like when running as daemon ("not in the
foreground"); therefore the path to the configuration file must be relative to
"/" (or the chroot() directory), which basically is "not relative", to ensure
that "kill -HUP" and the "REHASH" command work as expected later on.

This fixes parts of bug #127.

2205227c3b WHO #channel: don't limit list size
It makes no sense to limit the list size when doing WHO for a channel
and not to return all the users in that channel, so I removed the check.

the list will be "penalized" one second more (then 2 in total).

360a254be0 Enhance "ServiceMask" to handle a list of masks
The "ServiceMask" variable in "Server" blocks now can handle more than
one mask using the new MatchCaseInsensitiveList() function.

This makes marking "service clients" much more specific, which is a
good thing per se, but which is the prerequisite for reasonably
blocking these nick names, too (see commit a6dd2e3 for details).

a6dd2e33c2 Block nicknames that are reserved for services
This patch introduces the new function Conf_NickIsBlocked() which checks
if a given nick name matches with the "service mask" of a configured server.
And Client_CheckNick() uses this information to deny such names for regular
IRC users.

So nick names intended for IRC services are more protected and can't be used
by regular users even when the "services pseudo-server" isn't connected to
the network.

But please note:

Up to now, there can be only one "ServiceMask" pattern per server, which
most probably blocks much more nick names than really required ...
So "ServiceMask" should allow more than one pattern which can be more
specific, and most probably it should be possible to block nick names in
the global server configuration as well.

Nick names introduced by other servers/services are never restricted.

3 new channel user modes have been added.

Half Op: +h(Prefix: %) can set the channel modes +imntvIbek
and kick all +v and normal users.

Admin: +a(Prefix: &) can set channel modes +imntvIbekoRsz and kick all
+o, +h, +v and normal users.

Owner: +q(Prefix: ~) can set channel modes +imntvIbekoRsz and kick all
+a, +o, +h, +v and normal users

d0bb185cf5 Hashed hostnames for CloakHost
Implemented support for hashed hostnames for CloakHost. The admin can
use '%x' in both the CloakHost and CloakHostModeX setting. The config
option CloakHostModeX was renamed to CloakHostSalt. This salt is used
for both cloaking options.

49385a98b2 Implemented hashed cloaked hostnames for +x
CloakHostModeX can now contain '%x'. It will be replace by the hash of
the original client hostname. The new config option CloakHostModeXSalt
defines the salt for the hash function. When CloakHostModeXSalt is not
set a random salt will be generated after each server restart.

Spelling fix in defines.h

684e50f0a4 Correctly handle asynchronously re-established server links
Don't try to establish an outgoing server link after DNS lookup when this
server re-connected on its own in the meantime.
In addition, log a warning message if we try to update the connection
index of an already connected server structure -- and ignore it.

Up to now, both behaviour could lead to a race when the remote server
connects to this daemon while it still prepares the outgoing connection:

 - The local server prepares the new outgoing connection ...
 - in the meantime the remote server becomes connected and registered.
 - Now the new outgoing connection overwrites the (correct) socket handle,
 - then the 2nd connection becomes disconnected: "already registered",
 - and the 1st connection becomes unhandled ("gets lost") because the
   configuration structure is reset because of the wrong socket handle.

This patch hopefully fixes all these problems.

This patch implements the core functions to support "IRC Capabilities"
and the IRC "CAP" command as used by other servers and specified here:
<http://www.leeh.co.uk/draft-mitchell-irc-capabilities-02.html>.

It enables ngIRCd to support the defined handshake, but it doesn't
implement any capabilities, so "CAP LS" and "CAP LIST" always return
the empty set and "CAP REQ ..." always fails with "CAP NAK".

257fe922d2 getpid.sh: Fix testcase error for Debian using sbuild
When

 * building the ngircd Debian package (on Linux at least) and
 * using the sbuild build system,

the command "ps -af" does not include the commands running inside the
sbuild system. Therefore, start-server.sh will report a fail as getpid.sh
cannot not  find the ./T-ngircd1 just started although it's actually
running. This results in a funny build log ...

         starting server 1 ... failure!
   FAIL: start-server1
         running connect-test ... ok.
   PASS: connect-test

The self-test of getpid.sh however will likely succeed as it's happy if
it sees any process with "sh" somewhere in the name. Things go downhill
from there.

The confusing things are:

  * The alternative cowbuilder/pbuilder does not have this problem.
  * The alternative usage "ps ax" does fine.

So, as a quick hack, the patch attached adds another switch to getpid.sh.

1068f88377 Don't log "ngIRCd hello message" two times
Start "regular" logging not until the configuration file has been read in
and "SyslolgFacility" is set, and log all configuration errors using the
generic "daemon" facility.

So if there are no configuration errors, logging starts right after parsing
the configuration and we log the configuration file used _after_ reading it.
But this is no problem because every configuration error message includes
the configuration file name as well.

(The "double hello" has been introduced by commit 3641e51109)

871760583c Enhance server command limits
This patch updates the limits for handling commands from a remote server:

 - "<user count> / 5 + <min>" using "<min>=10" during normal operation,
 - the above count multiplied with 5 while servers are syncing.

The intention is to a) make the limit dependent of the number of users
in the network (the more users, the more commands required to sync) and
b) to significantly rise this limit while servers are joining the network
to make the login and synchronization faster.

bc20f9ec10 Send a PING at the end of the server sync to detect it
At the end of sending all "state" to the remote server, a PING command
is sent to request a PONG reply. Until then, no "regual" PING was sent,
so Conn_LastPing(<connection>) is null and now becomes non-null in the
PONG command handler.

So the servers are still synchronizing when Conn_LastPing(<connection>)
is 0, which could easily be tested.
