Summary0007731: IRCBridgeModule random connect issues
DescriptionThe IRCBridgeModule will randomly fail to connect to a server or in some cases the connection may be unresponsive. Some research turned up that other client and bridge projects have run into similar problems as well. Apparently it is caused by trying to send certain commands such as JOIN before being fully registered with the IRC network. The solution was to wait for the RPL_WELCOME that indicates being fully registered with the IRC network and many also recommended waiting to receive the MOTD (or the response indicating there is no MOTD). A properly configured server should send both. Then it is safe to proceed with other commands.

I've created a patch that makes the module wait until it receives the welcome and MOTD responses before sending the initial JOIN request. Have tested it across a number of networks and have 100% success in connecting now with no further problems afterwards, instead of failing half or more of the attempts.
TagsNo tags attached.

Applied a alternative fix on avinationmerge branch. Keep tracking of welcome and motd should not be necessary. The blind try to join on connect should be avoided. Some irds may ignore it completely until a valid user is accepted and created.
