Do not chmod +s chvt: instead, rely on sudo

The SUID flag may be lost on update, and relying on sudo is
slightly more secure.

We create a file in /etc/sudoers.d/ : these files are sourced by
default since sudo 1.7.2p1-1 (Ubuntu 10.04 lucid, Debian squeeze).

Fixes #723.
*/releases: Specify if a release should be tested or not

Each release line is now in the following format:
`release[*][|other,key,words]`

 - * indicates that the release is unsupported
 - keywords are comma-separated, and can currently be `test` or
   `notest`. Default is for supported releases to be tested (can
   be overridden with `notest`), and unsupported ones not to be
   tested (can be overridden with `test`).

enter-chroot: Remap devbroker-access group.

Merge pull request #1189 from drinkcat/sid-lxde-no-wicd

lxde: Do not install wicd (network manager)

test/12-edit-chroot: Install cli-extra to better test restore bin
Merge pull request #1131 from drinkcat/splittest+edit-chroot-fix

installer: Allow host-bin restoration only.
tests/30-audio: Fix dd command, better pulseaudio test.

Incorrect dd direction might be causing the test to fail
occasionally (#1101).
Set UID_MIN to 1001 to make sure that useradd does not automatically add users with UID 1000.

This guarantees that UID 1000 is available when post-common adds the main user at the end of the first run of crouton.

Protect GID 1000 in the same way.

Fixes a bug when xbmc is selected during the Arch install (the xmbc user created by the package steals UID 1000).
