    use lazy umount when umount returns EBUSY

    When the umount fails, we force the umount and make the mount point
    unaccessible by using a lazy umount.

commit e0dc0de76ed1ad9e284a37bd01268227d4eae8c9

    set terminal settings when console is a tty

    As the console output can be a tty, we want to have the terminal to
    be set as a specific manner to not echo and receive signals from the
    keyboard.

commit 63376d7db32acf2f8582627e5ff01d8d3f0d46d1
Author: Daniel Lezcano <dlezcano at fr.ibm.com>

    allocate a console to be proxied

    The actual behaviour of the console is messy as:
     * it relies on a heuristic (tty or not, rootfs or not, etc ...)
     * the container init stole the tty and we lose the control

    The following patch:
     * allocates a tty
     * maps this tty to the container console
     * proxy the io from the console to the file specified in the configuration
     lxc.console=<file>

    That allows to specify a file, a fifo, a $(tty), and can be extended with an
    uri like file://mypath, net://1.2.3.4:1234, etc ...
    That solves the problem with the heuristic and the container does no longer stole
    our current tty.

    Note by default, the console output will go to a blackhole if no configuration is
    specified making the container showing nothing.

    In order to access the console from the tty, use

     lxc-start -n foo -s lxc.console=$(tty)

    I propose the make the container to daemonize by default now.

    I tried the following:

     in a shell:
      touch /var/lib/lxc/foo/console
      tail --retry -f /var/lib/lxc/foo/console
     in another shell:
      lxc-start -n foo -s lxc.console=/var/lib/lxc/foo/console
