On some systems (namely Windows), syscall.Rlimit is not defined, and
makes the build fail.
This fixes the build by making the rlimit calls only run on archs where
it is defined, defaulting to a stub on other systems.

Previously, when we sent READ for an upstream which was disconnected,
we would fail with an error. This is because we called unmarshalEntity,
which checked that the upstream was in the connected status.
But we don't need to be connected to update the READ timestamp, this is
a purely offline (wrt the upstream) operation.
This simply switches the call from unmarshalEntity to
unmarshalEntityNetwork to fix the issue.
When the client supports draft/chathistory, no need to request
delivery receipts via PING messages. Let's just not leave delivery
receipts alone. They'll go stale but should be never used (or used
by a non-chathistory client).
When fetching messages via draft/chathistory from a conversation
with another user, soju would send the following:
:sender PRIVMSG sender :hey
instead of
:sender PRIVMSG recipient :hey
because the file-system message store format doesn't contain the
original PRIVMSG target.
Fix this by doing some guesswork.
READ lets downstream clients share information between each other about
what messages have been read by other downstreams.
Each target/entity has an optional corresponding read receipt, which is
stored as a timestamp.
- When a downstream sends:
READ #chan timestamp=2020-01-01T01:23:45.000Z
the read receipt for that target is set to that date
- soju sends READ to downstreams:
- on JOIN, if the client uses the soju.im/read capability
- when the read receipt timestamp is set by any downstream
The read receipt date is clamped by the previous receipt date and the
current time.
A previous fix (d4b7bb02da) only fixed sending echo-message for
TAGMSG to self. We also need to send echo-message for TAGMSG to
other targets.

Instead of always requiring users to explicitly specify the network
name, guess it from the downstream connection.
Network commands are left as-is because it's not yet clear how to
handle them.
Right now there is no consistent ordering in the network list:
no ORDER BY in the DB, and network updates move entries to the end.
Let's always sort by network ID so that users don't see the entries
move around.
I've contemplated sorting by Network.GetName() instead, but:
- Clients have now way to figure out dynamic order changes, e.g.
when renaming a network.
- Some clients might use ISUPPORT NETWORK when a user hasn't
explicitly named a network, but soju won't use that for ordering,
leading to non-alphabetic ordering in the client.
Let's leave it to clients to sort the networks by display name if
they want to.
