lxc 0.7.5-3ubuntu57 source package in Ubuntu

Changelog

lxc (0.7.5-3ubuntu57) precise-proposed; urgency=low

  [ Serge Hallyn ]
  * 0083-always-close-all-fds.patch: Have lxc-start always run with
    --close-all-fds.  There is no advantage to having lxc-start fail with
    inherited fds.  (LP: #1003583)
  * debian/lxc-net.upstart: don't put '()' after call to cleanup.
    (LP: #1000174)

  [ Stéphane Graber ]
  * Sync lxc-ubuntu with the one in Quantal:
    - Bugfixes:
      + Update list of extra packages for debootstrap to only include vim
        and ssh. The others were only relevant when we were still using the
        minbase variant. (LP: #996839)
      + Update default /etc/hosts to match that of a regular Ubuntu system.
        (adds missing ipv6 aliases) (LP: #1004108)
      + Make sure /etc/resolv.conf is valid before running any apt command.
        Fixes a potential race condition (no report of it at this time).

    - Improvements we get by pulling the whole patch from Quantal.
      These don't contain any user behaviour change but will make
      cherry-picking any further change much easier.
      + Drop any hardcoded Ubuntu version check and replace by feature
        checks instead. This removes the need for SRUs whenever we release
        a new Ubuntu.
      + Format lxc-ubuntu to consistently use 4-spaces indent instead
        of mixed spaces/tabs.
      + Update default /etc/network/interfaces to include the header.
      + Drop support for never supported releases (gutsy on sparc).
      + Update template help message for release and arch parameters.
        Old string was only listing i386 and amd64, which is no longer
        accurate (as of 12.04).
        (This string isn't translated)
      + Switch default Ubuntu version from lucid to precise for systems
        that don't have lsb_release (won't affect Ubuntu)

  * Sync lxc-start-ephemeral with the one in Quantal:
    - Switch lxc-start-ephemeral from unreliable parsing of DHCP lease files
      to using "ip netns" to retrieve the IP from the container's network
      namespace. (LP: #994752)
    - Fix a race in lxc-start-ephemeral where the container isn't yet
      running when trying to get its IPs.
    - Update a few calls so that lxc-start-ephemeral can be called as a
      user (ensure consistent usage of sudo across the script). (LP: #1004069)
