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.

Closes #1915

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’.

There's no obvious need to strdup() the name of the container in the handler.
We can simply make this a pointer to the memory allocated in
lxc_container_new().

In case cgroup namespaces are supported but we do not have CAP_SYS_ADMIN we
need to mount cgroups for the container. This patch enables both privileged and
unprivileged containers without CAP_SYS_ADMIN.

When attaching to a container's namespaces we did not handle the case where we
inherited namespaces correctly. In essence, liblxc on start records the
namespaces the container was created with in the handler. But it only records
the clone flags that were passed to clone() and doesn't record the namespaces
we e.g. inherited from other containers. This means that attach only ever
attached to the clone flags. But this is only correct if all other namespaces
not recorded in the handler refer to the namespaces of the caller. However,
this need not be the case if the container has inherited namespaces from
another container. To handle this case we need to check whether caller and
container are in the same namespace. If they are, we know that things are all
good. If they aren't then we need to attach to these namespaces as well.
