This commit takes insert query compilation and transaction creation out
of the critical loop for migrating message logs. I have tested with
the sqlite backend, and a speedup of approximately 40x has been achieved
for log migration.
No need to re-check that a Web Push subscription is valid every
time a downstream connects. Mobile devices may reconnect pretty
frequently.
Check at most once a day.
PostgreSQL tests use pg_temp only. pg_temp is never searched for FTS
objects, so creating then altering an FTS configuration will not work
because PostgreSQL will not be able to find the FTS configuration it
just created.
Instead, we explicitly refer to the FTS objects with their full name
including their prefix, which makes PostgreSQL able to find the object.
This is only needed for tests.

This adds a new config option, `logs db`, which enables storing chat
logs in the soju database.
Regular store options, CHATHISTORY options, and SEARCH operations are
supported, like the fs logs backend.
Messages are stored in a new table, Message. In order to track the list
of targets we have messages for in an optimized manner, another database
is used: MessageTarget.
All new requests are backend by indexes so should be fast even with
hundreds of thousands of messages.
A contrib script is provided for migrating existing logs fs chat logs to
the database. It can be run with eg:
go run ./contrib/migrate-logs/ logs/ sqlite3:soju.db

We need to use sql.NullTime, otherwise we get errors like these:
sql: Scan error on column index 7, name "downstream_interacted_at": unsupported Scan, storing driver.Value type <nil> into type *time.Time
Add a new flag to disable users. This can be useful to temporarily
deactivate an account without erasing data.
The user goroutine is kept alive for simplicity's sake. Most of the
infrastructure assumes that each user always has a running goroutine.
A disabled user's goroutine is responsible for sending back an error
to downstream connections, and listening for potential events to
re-enable the account.
The soju username is immutable. Add a separate nickname setting so
that users can change their nickname for all networks.

Some WebPushSubscription entries aren't tried to a network, in
which case the "network" column is NULL. But then all users share
the same row. Oops.
Fortunately network-less subscriptions aren't used for anything
yet, they're just stored. So the impact should be minimal.
