console: report detach message on demand

When users pass -1 there's there won't be an escape sequence to exit the
console so no need to print a misleading info message about how to detach.

console: fix console info message

Hi,

I try to create a Slackware container in a Slackware64 14.2 current and
find that wget depends on libunistring.

So I add libunistring to the package list.

If a console log file was specified this flag indicates whether the contents of
the ringbuffer should be written to the logfile when a request is sent to the
ringbuffer.
Signed-off-by: Christian Brauner <christian.brauner@ubuntu.com>

When users request that the container keep a console ringbuffer we will not
continously write to the on-disk logfile as mirroring the contents of the
in-memory ringbuffer on-disk is costly and complicated. Instead, we dump the
ringbuffer contents on-disk when the container stops or fails to start. This
way users can still diagnose problems or retrieve the last contents of the
ringbuffer on-disk.

We need to have lxc_attach() distinguish between a caller specifying specific
namespaces to attach to and a caller not requesting specific namespaces. The
latter is taken by lxc_attach() to mean that all namespaces will be attached.
This also needs to include all inherited namespaces.
