Because the `fetch` wget wrapper outputs files to stdout we may end up in a
situation where wget fails but the files are still created. This can happen
e.g. when the host date is out of sync leading to a failed certificate
check, resulting in the creation of empty key files.

Once the empty files have been created the template will try to use them which
causes the certificate check to fail.

By using `-s` instead of `-f` the template will re-fetch the files unless they
exist AND have a size greater than zero.

To match names beginning with the letters "f" or "b" one can use
the regular expression "[fb].*" or "(f|b).*", but not "[f|b].*",
which would match strings beginning with "f", "|", or "b".

Since some remounts/umounts is executed in the plamo shutdown script,
the filesystem on where a container exists might be mount as
read-only. This patch delete some mounts and umounts from the shutdown
script. It also delete hwclock setting process.

And delete an unncecessary output.

When the "lxc.rootfs.path" property is not set and users request a container
copy we would segfault since strstr() would be called on a NULL pointer.

This is technically not necessary but it is a privilege sensitive operation.
Meaning if anyone wants to do something that requires privilege it should be
done before the id switch. So let's move the id switch immediately before the
exec so that it's called at the last possible moment.

In the past, if the console client exited, lxc_console_cb_con return 1. And
the lxc_poll will exit, the process will wait at waitpid. At this moment, the
process could not handle any command (For example get the container state
LXC_CMD_GET_STATE or stop the container LXC_CMD_STOP.).

I think we should clean the tty_state and return 0 in this case. So, we can use
the lxc-console to connect the console of the container. And we will not exit
the function lxc_polland we can handle the commands by lxc_cmd_process

Reproducer prior to this commit:
- open a new terminal, get the tty device name by command tty /dev/pts/6
- set lxc.console.path = /dev/pts/6
- start the container and the ouptut will print to /dev/pts/6
- close /dev/pts/6
- try an operation e.g. getting state with lxc-ls and lxc-ls will hang

Closes #1787.
