Update checks for required and optional header files, data types, and functions.

And use newer features such as bug reporting address and project URL.

This fixes the following warning message when building without SSL support: conn.c: In function "New_Connection": conn.c:1365: warning: unused parameter "IsSSL" Introduced by commit 01b62202.

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.

This patch allows you to define &SERVER in a [Channel] block yourself and to overwrite the built-in topic and channel modes. Fixes bug #131.

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. But if there are more than MAX_RPL_WHO(25) replies, the client requesting the list will be "penalized" one second more (then 2 in total). This fixes bug #125.

Some systems, notably FreeBSD 4.x, do have the kqueue() function but lack the definition of EV_SET() in their header files -- but don't worry, we can #define it on our own ;-) Definition taken from /usr/include/sys/event.h of FreeBSD 8.1. Patch tested on FreeBSD 4.1 by Götz Hoffart. Thanks!

Conn_StartLogin() is called after the connection has been established and fully innitialized, including the SSL handshake, for example. Up to this patch, the "NoticeAuth" option broke the SSL handshake ...

We can't handle more connections than accept(2) can supply, and accept(2) returns an "int" ...

This numeric is sent to the client each time it changes its displayed hostname using "MODE +/-x", and if "CloakHost" is set right after the MOTD has been sent.

Not only cloak the hostname in Client_MaskCloaked(), but also in Client_HostnameCloaked() -- so move the actual cloaking to this function and call it in Client_MaskCloaked() to get the (cloaked) hostname. This fixes USERHOST not displaying the correctly cloaked hostname, for example.

This patch series allows ngIRCd to support the user mode "B" ("Bot flasg"): it is settable and unsettable by every (non-restricted) client. According to DNS777, this is how Unreal and InspIRCd do behave, so do we :-) By Alexander Barton (1) and DNS777 (1) * umode-B: Add new user mode "B" to doc/Modes.txt Implement an Unreal-like user mode "B" ("Bot mode")

By Alexander Barton (1) and DNS777 (1) * recognize-umode-R: Only allow IRC services to modify user mode "R" Recognize user mode "R"

This allows users to unset the user mode "R".

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).
