Fix sending CAP END twice when SASL is not used
When SASL is not used, we should only send CAP END after we send a CAP
REQ. Previously CAP END was sent both after a CAP REQ and a CAP ACK,
resulting in two CAP END messages.

Sending a CAP END right after the CAP REQ rather than waiting for the
CAP ACK/NAK saves 1 RTT.

Fix a null access due to assigning nil to the member memberships map
Even though the memberships map has type map[string]*memberships
(with memberships being defined as []membership), the default value for
that map should not be `nil` but a pointer to a nil slice.

This fixes a segfault on some servers before user channel prefixes are
sent.

Fix parsing MODE messages by updating channel memberships
Previously, we only considered channel modes in the modes of a MODE
messages, which means channel membership changes were ignored. This
resulted in bugs where users channel memberships would not be properly
updated and cached with wrong values. Further, mode arguments
representing entities were not properly marshaled.

This adds support for correctly parsing and updating channel memberships
when processing MODE messages. Mode arguments corresponding to channel
memberships updates are now also properly marshaled.

MODE messages can't be easily sent from history because marshaling these
messages require knowing about the upstream available channel types and
channel membership types, which is currently only possible when
connected. For now this is not an issue since we do not send MODE
messages in history.

Add support for multiple user channel memberships
User channel memberships are actually a set of memberships, not a single
value. This introduces memberships, a type representing a set of
memberships, stored as an array of memberships ordered by descending
rank.

This also adds multi-prefix to the permanent downstream and upstream
capabilities, so that we try to get all possible channel memberships.

40ee5e8405 Fix not properly marshaling self in single-server mode
In single-server mode, we don't need to add a /network suffix when
marshaling, but we still need to replace our nick with the downstream
nick.

Add support for detached channels
Channels can now be detached by leaving them with the reason "detach",
and re-attached by joining them again. Upon detaching the channel is
no longer forwarded to downstream connections. Upon re-attaching the
history buffer is sent.

a99d6dd019 Fix joining only one saved channel per network
This fixes a serious bug added in 276ce12e, where in newNetwork all
channels point to the same channel, which causes soju to only join a
single channel when connecting to an upstream network.

This also adds the same kind of reassignment of a for loop variable in
user.run(), even though that function currently works correctly, as a
sanity improvement in case this function is changed in the future.

Use a lock to protect conn.{closed,outgoing}
Unfortunately, I don't think there's a good way to implement net.Conn
semantics on top of channels. The Close and SendMessage methods should
gracefully fail without panicking if the connection is already closed.
Using only channels leads to race conditions.

We could remove the lock if Close and SendMessage are only called from a
single goroutine. However that's not the case right now.

7b35757bac Add support for the irc+insecure address scheme
Some servers do not support TLS, or have invalid, expired or self-signed
TLS certificates. While the right fix would be toi contact each server
owner to add support for valid TLS, supporting plaintext upstream
connections is sometimes necessary.

This adds support for the irc+insecure address scheme, which connects to
a network in plain-text over TCP.

19795a2321 Add support for IRC address schemes
This is preparatory work for adding other connection types to upstream
servers. The service command `network create` now accepts a scheme in
the address flag, which specifies how to connect to the upstream server.

The only supported scheme for now is ircs, which is also the default if
no scheme is specified. ircs connects to a network over a TLS TCP
connection.

19854b7ec7 Unmarshal nicks in texts of PRIVMSG and NOTICE from downstreams
When writing a PRIVMSG or NOTICE on a channel, it is very common to use
autocompletion to mention other users on that channel. When using soju
in multi-network mode, all users will have their nicked suffixed by
`/network`. This suffix should be removed before sending it upstream.

This adds support for removing all `/network` suffixes in messages sent
to a channel of that network.

7f74055380 Add support for custom network on-connect commands
Some servers use custom IRC bots with custom commands for registering to
specific services after connection.

This adds support for setting custom raw IRC messages, that will be
sent after registering to a network.

It also adds support for a custom flag.Value type for string
slice flags (flags taking several string values).

Per-entity ring buffers
Instead of having one ring buffer per network, each network has one ring
buffer per entity (channel or nick). This allows history to be more
fair: if there's a lot of activity in a channel, it won't prune activity
in other channels.

We now track history sequence numbers per client and per network in
networkHistory. The overall list of offline clients is still tracked in
network.offlineClients.

When all clients have received history, the ring buffer can be released.

In the future, we should get rid of too-old offline clients to avoid
having to maintain history for them forever. We should also add a
per-user limit on the number of ring buffers.
