The commit 5a087e05 introduced a second parameter (conf) to the
cgroup escape() function which was never set in do_dump(). Instead of
taking it from opts->handler->conf it is now used from c->lxc_conf.

Fixes: 5a087e05 ("cgroups: don't escape if lxc.cgroup.keep is true")

Make use of the new socket option, NETLINK_DUMP_STRICT_CHK, that
userspace can use via setsockopt to request strict checking of headers
and attributes on dump requests.

To get dump features such as kernel side filtering based on data in
the header or attributes appended to the dump request, userspace
must call setsockopt() for NETLINK_DUMP_STRICT_CHK and a non-zero
value. This is necessary to make use of the IFA_TARGET_NETNSID property.

attach: reset signal mask

Since we introduced clean exit from the mainloop when SIGTERM is sent we
changed the signal mask of the parent process but we never reset the
signal mask for the actual attached process.

Closes #399.
