Subject: [PATCH] Send the last error for disconnected networks in network
 status

This adds support for sending the exact error message of a network when
it is disconnected, in the reply to the service command `network
status`. This lets users easily examine why a network is currently
disconnected.

No lock is needed because all reads and writes of network.lastError are
made in the user goroutine.

Closes: https://todo.sr.ht/~emersion/soju/28
