Doxygen: remove own header and CSS file
Use the ones of Doxygen instead, this has the advantage that we benefit of new functionality of Doxygen without having to make changes.
Make write buffers bigger, but flush early
This patch - makes the server write buffer bigger: 64k, - makes the regular write buffer bigger: 32k, - tries to flush the write buffer starting at 4K. Before this patch, a client got disconnected if the buffer flushing at 4k failed, now regular clients can store up to 32k and servers up 64k even if flushing is not possible at the moment (e.g. on slow links).
Better check for invalid IRC+ PASS command
Don't do a NULL-pointer dereference when a remote server using the IRC+ protocol sends an invalid PASS command without the required <serverversion> parameter ...
Read_Request(): don't access possibly free'd CLIENT structure
Handle_Buffer() can shut down connections and remove clients, so after calling it, we have to make sure that our CLIENT pointer is still valid.
Log "Can't read MOTD file" as "configuration error"
Now this error message is displayed in the console without debug prefix when running the configuration test (--configtest).
Allow "Port = 0" in [Server] blocks
Port number 0 marks remote servers that try to connect to this daemon, but where this daemon never tries to establis a connection on its own: only incoming connections are allowed.
conf: fix 'Value of "..." is not a number!' for negative values
Don't use isdigit() function any more, because it only checks the first character of the variable value and because it doesn't know about the minus sign which is required e.g. for "Group = -1".
Don't read MOTD file twice
The MOTD file is read in Read_Config(), so don't read it when handling the "MotdFile" configuration variable. Instead make sure that it is initialized properly when (re-)reading the configuration.
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 :-(
Implement channel mode 'O': "IRC operators only"
This channel mode is used on DALnet (bahamut), for example.
