unrealircd: Update to 4.2.2.

Changes between version 4.2.1 and 4.2.2:


    Quicker connection handshake for clients which use CAP and/or SASL.
    With "TOPIC #chan" and "MODE #chan +b" (and +e/+I) you can see who set the topic and bans/exempts/invex. The default is to only show the nick of the person who set the item. This can be changed 
(not the default) by setting:

    set { topic-setter nick-user-host; };
    set { ban-setter nick-user-host; };

    The 'set by' and 'set at' information for +beI lists are now synchronized when servers link. You still see the MODE originating from the server, however when the banlist is queried you will now 
be able to see the original nick and time of the bansetter rather than If you want the OLD behavior you can use: set { ban-setter-sync no; };
    The default maximum topic length has been increased from 307 to 360.
    You can now set more custom limits. The default settings are shown below:

    set {
            topic-length 360; /* maximum: 360 */
            away-length 307; /* maximum: 360 */
            quit-length 307; /* maximum: 395 */
            kick-length 307; /* maximum: 360 */

    The message sent to users upon *LINE can now be adjusted completely via set::reject-message::kline and set::reject-message::gline.
    New set::anti-flood::max-concurrent-conversations which configures the maximum number of conversations a user can have with other users at the same time.
    Until now this was hardcoded at limiting /MSG and /INVITE to 20 different users in a 15 second period. The new default is 10 users, which serves as a protection measure against spambots.
    New set::max-targets-per-command which configures the maximum number of targets accepted for a command, such as 4 to allow e.g. /MSG nick1,nick2,nick3,nick4 hi.
    Also changed the following defaults (previously hardcoded):
        PRIVMSG from 20 to 4 targets, to counter /amsg spam
        NOTICE from 20 to 1 target, to counter /anotice spam
        KICK from 1 to 4 targets, to make it easier for channel operators to quickly kick a large amount of spambots
    Added INVITE and KNOCK flood protection (command rate limiting):
        set::anti-flood::invite-flood now defaults to 4 per 60 seconds (previously the effective limit was 1 invite per 6 seconds).
        set::anti-flood::knock-flood now defaults to 4 per 120 seconds.
    New set::outdated-tls-policy which describes what to do with clients that use outdated SSL/TLS protocols (eg: TLSv1.0) and ciphers.
    The default settings are to warn in all cases: users connecting, opers /OPER'ing up and servers linking in. The user will see a message telling them to upgrade their IRC client.
    This should help with migrating such users, since in the future, say one or two years from now, we would want to change the default to only allow TSLv1.2+ with ciphers that provide Forward 
Secrecy. Instead of rejecting clients without any error message, this provides a way to warn them and give them some time to upgrade their outdated IRC client.

Major issues fixed:

    Crash issue in the 'websocket' module.

Minor issues fixed:

    The advertised "link-security" was incorrectly downgraded from level 2 to 1 if spkifp was used as an authentication method.
    In case of a crash, the ./unrealircd backtrace script was not working correctly in non-English environments, leading to less accurate bug reports.
    Various crashes if a server receives incorrect commands from a trusted linked server.
    A number of memory leaks on REHASH (about 1K).
    SASL was not working post-registration, eg: when services link back in. This is now fixed in UnrealIRCd, but may require a services update as well.


    The noctcp user mode (+T) will now only block CTCP's and not CTCP REPLIES. Also, IRCOps can bypass user mode +T restrictions.
    The server will warn if your ulines { } are matching UnrealIRCd servers.
    The m_whox module now contains various features that m_who already had.
    Also, m_whox will try to convert classic UnrealIRCd WHO requests such as "WHO +i" to whox style "WHO i".
    Unfortunately auto-converting WHO requests is not always possible. When in doubt the WHOX syntax is assumed. Users are thus (still) encouraged to use the whox style when m_whox is loaded.

For module coders:

    New hook HOOKTYPE_WELCOME (aClient *acptr, int after_numeric): allows you to send a message at very specific places during the initial welcome.
    New Isupport functions: IsupportSet, IsupportSetFmt and IsupportDelByName.
    The M_ANNOUNCE flag in the command add functions should no longer be used as CMDS= is removed. Please update your module.
    New "SJSBY" in PROTOCTL, which is used in SJOIN to sync extra data. See the last part of the SJOIN documentation.
    For a command with 2 arguments, eg "PRIVMSG #a :txt", parv[1] is "#a", parv[2] is "txt" and parv[3] is NULL. Any arguments beyond that, such as parv[4] should not be accessed. To help module 
coders with detecting such bugs we now poison unused parv[] elements that should never be accessed. Note that without this poison your code will also crash, now it just crashes more consistently.

IRC protocol:
This section is intended for client coders and people interested in IRC protocol technicalities

    Many changes in the tokens used in numeric 005 (RPL_ISUPPORT):
        Removed CMDS= because this was an unnecessary abstraction and it was not picked up by any other IRCd.
        The tokens KNOCK MAP USERIP have been added (moved from CMDS=..)
        STARTTLS is no longer advertised in 005 since doing so would be too late. Also, STARTTLS is not the preferred method of using SSL/TLS.
        Added TARGMAX= to communicate set::max-targets-per-command limits.
        Removed the MAXTARGETS= token because TARGMAX= replaces it.
        Added DEAF=d to signal what user mode is used for "deaf"
        Added QUITLEN to communicate the set::quit-length setting (after all, why communicate length for KICK but not for QUIT?)
        The 005 tokens are now sorted alphabetically
    When hitting the TARGMAX limit (set::max-targets-per-command), for example with "/MSG k001,k002,k003,k004,k005 hi", you will see:
    :server 407 me k005 :Too many targets. The maximum is 4 for PRIVMSG.
    When hitting the set::anti-flood::max-concurrent-conversations limit (so not per command, but per time frame), you will see:
    :server 439 me k011 :Message target change too fast. Please wait 7 seconds
    When hitting the set::anti-flood::invite-flood limit you will get:
    :server 263 me INVITE :Flooding detected. Please wait a while and try again.
    When hitting the set::anti-flood::knock-flood limit you will get:
    :server 480 me :Cannot knock on #channel (You are KNOCK flooding)
    Not a protocol change. But when a server returns from a netsplit and syncs modes such as: :server MODE #chan +b this!is%an.old.ban@localhost
    Then later on you can query the banlist (MODE #chan b) and you may see the actual original setter and timestamp of the ban. So if a user wishes to see the banlist then IRC clients are encouraged 
to actively query the banlist before displaying it. Fortunately most clients do this.
    If the set::topic-setter or set::ban-setter are set to nick-user-host then the "added by" field in numerics that show these entries will contain nick!user@host instead of nick, eg:
    :server 367 me #channel this!is%some.ban@localhost bansetter! 1549461765
