If lxc-init receives a SIGALRM, a timeout, it kills all the processes
of the container with SIGKILL. That will prevent the container to be
stuck when one process ignore the SIGTERM signal.

Each time a process exits, the timeout is resetted.

When lxc-init receives a SIGTERM, let's kill all the processes of
the pid namespace with kill -1. So the exit of the container will
happen gracefully with processes death cascade.

As pointed out by Dan Smith, when a container is being stopped, it must
also be unfrozen after posting the SIGKILL. Otherwise if the container
is frozen when the SIGKILL is posted, the SIGKILL will remain pending
and the lxc-stop command will block until lxc-unfreeze is explicitly
called).

(lxc-stop waits for the container to exit and close the socket but since
the container is frozen, lxc-stop will block).

A write to the freezer.state file does not gurantee that the state has
changed. To ensure that the freezer state is either FROZEN or THAWED,
read the freezer state and if it has not changed, repeat the write.

Changelog[v2]:
	- Minor reorg of code
	- Comments from Daniel Lezcano:
		- lseek() before each read/write of freezer.state
		- Have lxc_freeze_unfreeze() return -1 on error

If the pdeath signal is set after the synchro we have a window where
the parent exits with the pdeath signal not set.

In order to avoid that, we have to move the prctl before the synchro with
the parent so if the parent exits before we can set the pdeath signal, the
synchro will fail in any case and the container startup will be aborted.

Hello all!

    This bug stalked me for a while, but only now it bit me quite
badly... (Lost about an hour of work...)

    So the culprit: inside the fstab file for the `lxc.mount` option I
can use options like `ro` together with `bind`. Unfortunately the
kernel just laughs in my face and ignores any options I've put in
there... :) But not any more: I've updated `./src/lxc/conf.c`
(`mount_file_entries` function) so that when it encounters a `bind`
option it executes it twice (one without any extra options, and a
second time with the remount flag set.)

I've marginally (as in my particular case) tested it and it works.

Pointer comparison is buggy as they are never null.
For an ipv6 address configuration, we always zeroed the structure,
hence the bcast and acast structure are equal to in6addr_any.

Any change of this value means the user specified something different
in the configuration file, so we fail gracefully.
