8f1f67f1f0 Rate limit Web Push checks 
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.

1ccc7ce6d2 Add a database store for messages 
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

2713bcba34 Add administrative unix listen endpoint 
This adds support for listening on a Unix socket for administrative
connections, that then use a simple protocol for communicating with
the service (BouncerServ) as an administrator with a global context.

The wire format used by the Unix socket is IRC, but without
registration or overheads.

Example session:

    >>> BOUNCERSERV
    <<< 461 * BOUNCERSERV :Not enough parameters
    >>> BOUNCERSERV :n s
    <<< :gensou FAIL BOUNCERSERV :this command must be run as a user
    >>> BOUNCERSERV :u s
    <<< :gensou PRIVMSG * :marisa: 2 networks
    <<< :gensou PRIVMSG * :alice: 1 networks
    <<< :gensou BOUNCERSERV OK

a662091a9d server: fix panic stacktrace print formatting 
This change uses string formatting for the output of debug.Stack. The
output of debug.Stack is []byte, which isn't human readable.

d21fc06d88 server: cleanup user in defer 
If a user goroutine panics, this correctly removes it from the
global map instead of leaving a dangling entry behind.

578020e553 Add exponential backoff when re-connecting to upstream 
The first reconnection attempt waits for 1min, the second the 2min,
and so on up to 10min. There's a 1min jitter so that multiple failed
connections don't try to reconnect at the exact same time.
