The basic idea is sudo /bin/sh -c 'quoted_command'.  We use Paramiko's low-level API to set a timeout, get a pseudo tty, execute sudo and the (shell quoted) command atomically, wait just until sudo is ready to accept the password before sending it down the pipe, and then return the command's stdout and stderr.

This should be faster, as there are no unneeded sleeps.  There are no permissions issues reading the output.  It will raise socket.timeout if the command takes too long.  However, this is a per-read timeout, not a total execution timeout, so as long as the command is writing output and you are reading it, it will not time out.

Local and non-sudo commands remain unchanged, but should probably adopt a similar approach.

Since this is a significant change, it needs a lot of testing.  Also, someone smarter than I should double-check the quoting and execution, since it is a security issue.

Implemented optional "default-release" argument for apt module

The value is passed to apt-get's "-t" option. Useful for installing backports, e.g.:

  ansible webservers -m apt -a "pkg=nginx state=latest default-release=squeeze-backports"

Update secontext behavior in file module

Demonstrate what happens when there is no default context in the policy.

This adjusts behavior of file module such that removal of se* option
does not revert the file's selinux context to the default.  In order to
go back to the default context according to the policy, you can use the
context=default option.

Apt module support for installing/removing specific version of package

This uses standard APT syntax, e.g.:

    ansible webservers -m apt -a "pkg=nginx=1.1.19-1 state=installed"

It works like this:

{{ hostvars['127.0.0.1']['ansible_eth0']['ipv4']['address'] }}

Move setup.py stuff back to top level as "make sdist" was not working, plus, it makes sources cleaner.

Runner() usage to the new inventory model.

Use /var/tmp for root by default to avoid /tmp being mounted noexec, and segregate tmp files for other users
into their home directories.

non-sensical, but also if the user wrote a module that took none)

Call os.path.expanduser in modules so things work as expected even when using ./hacking/test-module script

Adds PKGBUILD file for Arch linux

Move manifest

Apt module spelling fixes

Distutils MANIFEST.in, setup.py -> packaging/distutils/ directory.

Adds missing depends (python2-yaml helps...)
Adds missing build deps (fakeroot)

Adds PKGBUILD file required to build Arch Linux packages

needed due to moving into packaging/debian?
