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.

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.

In order to enable proper unprivileged cgroup delegation on newer kernels we not
just need to delegate the "cgroup.procs" file but also "cgroup.threads". But
don't report an error in case it doesn't exist. Also delegate
"cgroup.subtree_control" to enable delegation of controllers to descendant
cgroups.

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.

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.

The configure checks for these use AC_CHECK_DECLS, which define the symbol
to 0 if not available - So adjust the code to match. From the autoconf
manual:
https://www.gnu.org/software/autoconf/manual/autoconf-2.65/html_node/Generic-Declarations.html)
For each of the symbols (comma-separated list), define HAVE_DECL_symbol (in
all capitals) to ‘1’ if symbol is declared, otherwise to ‘0’.
