To let modules know whether a client is currently in playback mode.
The clientbuffer module (#343) wants to update "last seen message"
timestamps in OnSendToClient() but it must avoid doing that while
in playback mode.
This allows implementing timestamp-based (eg. client specific - #343)
filtering of playback buffers. For clients that don't support server-time,
getting an accurate timestamp out of a raw buffer playline is impossible.
FindClient() is not enough, because there are no restrictions to used
identifiers. They don't necessarily need to be unique, and the same
identified client might re-connect meanwhile a ghost connection is
still hanging there.
The old AttachUser() that sent JOIN without topic or names replies
would leave clients in incomplete/broken state. JoinUser() was doing
two things; depending on passed arguments it was either joining user
on the channel on IRC, or attaching clients (properly). Now JoinUser()
joins the user on IRC, and AttachUser() attaches as expected from the
method names.
Store query buffers per query the same way it's done for channels.
This allows clients to implement persistent query buffers. Queries
remain open across clients and sessions until a client explicitly
sends a command to clear a (closed) query buffer.
A new config option AutoClearQueryBuffer that default to false
ensures behavioral backwards compatibility, and another config
MaxQueries protects from OOM eg. due to PM attacks.
Currently the connection timeout handling of znc uses three magic numbers, each
of which is at least repeated in two unrelated places. This commits defines the
numbers in CIRCNetwork and makes the other places just use this number.
This also renames PING_TIMEOUT to PING_FREQUENCY because I feel that describes
this constant better.
I am not really happy about the name NO_TRAFFIC_TIMEOUT that is used for the
real timeout, but I couldn't think of a better name. PING_TIMEOUT isn't good
because that sounds like the time between sending a PING and the resulting
timeout.

This patch splits CUserTimer into two other timers:
CIRCNetworkPingTimer: This timer sends PING messages to connected
client's and IRC servers.
CIRCNetworkJoinTimer: This timer enforces the MaxJoin setting by only
allowing a specified amount of channels to join at the same time.
JoinChans() is modified to reset the ping timer once we hit the MaxJoin.
This allows us to call it from any function without breaking the timing
logic.
Previous commit added support of it to Csocket.
When encoding is specified, core will convert incoming messages to UTF-8,
and outgoing messages from UTF-8.
When no encoding is specified, it will do nothing to bytes, like before.
This is to be changed somewhere in future, to have UTF-8 on wire by
default too.
When encoding's name starts with *, incoming messages will be treated as
UTF-8, if it is already correct UTF-8. Otherwise, it's converted.
Fix#151Fix#366
It was accidentally dropped in 0.207 because of the confusing name,
it looked too much like antiidle module.
Instead, this module tells broken clients like Colloquy that *status and
*module are "online". Otherwise those clients require user to always
prepend messages to *module with "/msg *module", even if the window of
*module's query is active.
Also fix the module to support network modules

This reverts commit db7c47f97d.
Too many joined channels at once started to cause disconnect because of
"Max SendQ Exceeded", which is not much better than previous Flood.
Now MaxJoins is 0 by default, which preserves the current behavior of
joining all channels at once. If someone experiences those disconnects
due to SendQ, they can tune MaxJoins.

If nicks are equal, it's not changed. The problem was that equality was
checked case-insensitively.
This makes some clients which compare nicks case-sensitively think that
JOINs which we send to them, are not related to the user, it's someone
else joining. So Konversation users which have lower case version of
their IRC nick configured in Konversation settings, didn't get their
channel opened when connecting to ZNC.
Thanks to Axanon for helping to investigate the issue.
