When a container is paused, signals are sent once the container has been
unpaused.
Instead of forcing the user to unpause a container before they can ever
send a signal, allow the user to send the signals, and in the case of a
stop signal, automatically unpause the container afterwards.
This is much safer than unpausing the container first then sending a
signal (what a user is currently forced to do), as the container may be
paused for very good reasons and should not be unpaused except for
stopping.
Note that not even SIGKILL is possible while a process is paused,
but it is killed the instant it is unpaused.

Before this patch, a log reader is able to block all log writes
indefinitely (and other operations) by simply opening the log stream and
not consuming all the messages.
The reason for this is we protect the read stream from corruption by
ensuring there are no new writes while the log stream is consumed (and
caught up with the live entries).
We can get around this issue because log files are append only, so we
can limit reads to only the section of the file that was written to when
the log stream was first requested.
Now logs are only blocked until all files are opened, rather than
streamed to the client.

The name/ID relationships are maintained separately from the memdb and
can be out of sync from any particular memdb snapshot. If a container
does not exist in the memdb, we must accept this as normal and not fail
the listing. This is consistent with what the code used to do before
memdb was introduced.
