The processor fact doesn't exist in LinuxVirtual.  Read /proc/cpuinfo
and check if it is QEMU.

The Facts class and subclasses no longer take a dict argument for
instantiation.  populate() now returns self.facts.
Other changes:
- Facts.__init__() takes over most of the work from populate() so that
  subclasses can benefit from its knowledge.
- Drop setting unknown facts to 'NA' in __init__() in various
  subclasses.
- Check for presence of facts in get_virtual_facts()
- Update ansible_facts() to use facts.update(<classname>().populate())

This changes and organizes facts into a base class Facts and several
sub classes that implement the necessary functionality.  The classes
are:
- Facts: base class.  Implements basic facts that should be common to a
  number of platforms.  It is also where SSH keys and SELinux facts are
  set.
- Hardware: A subclass of Facts that should be further
  subclassed per platform for CPU, memory, and related facts.
  - LinuxHardware: subclass of Hardware for Linux platforms
  - SunOSHardware: subclass of Hardware for SunOS platforms
  - FreeBSDHardware: subclass of Hardware for FreeBSD
- Network: A subclass of Facts that that should be further
  subclassed per platform for IP, both IPv4 and IPv6, information.
  - LinuxNetwork: Currently only implementation for determining network
    facts.
- Virtual: A subclass of Facts that that should be further
  subclassed per platform to determine virtual environment facts.
  - LinuxVirtual: Currently only implementation for determining virtual
    facts.

If facts are needed for additional platforms, one of the above classes
(eg Network) can be further subclassed and implement the necessary
functionality.

In addition, it fixes get_network_facts() to work on Fedora17.  That
broke due to changes to ifconfig output.

Added code to allow insertion of boilerplate into modules to make them able to share lots of code, the result
should be a huge reduction of total ansible source, at a slight cost of difficulty in original module development.

We need to apply this now to all modules, but may need to have some exemptions to things like command, which should
subclass this module.

Pass through error message when repo not found

Service module outputting extra data

The service module was printing stuff to stderr, returning two
JSON dicts, not using consistent 'failed' values, had dead code
and unused variables.  Added detection for the case when service
status returns 'xxx is dead and pid file exists' and made the
code a bit easier to read.

Adding missing colon... can't believe I missed that... sorry

Conditional Imports should only import the first vars_file found in list

Conditional Imports should only import the first file in the list, not all of them. This change stops looping through the vars_files list as soon as a file is found.

Allow local plays to execute when --ask-sudo-pass is used on the command line

This reverts commit 0d53b1b0.

Fix typo while handling custom facts.

This fixes #611.

Plays and tasks now yell when they see parameters they do not understand, so that typos like 'var' for 'vars'
don't result in people having to ask questions about what is wrong with their playbook

    First pass of the Ansible EC2 inventory script

Fix for the way host variables were being swallowed, plus some overall simplification.   Deciding what
dictionary to use for templating now happens in exactly one place (executor_internal) and the "inject"
dictionary is passed to what needs it.

format fixes to output from fetch

with_items handling code should apply to all modules, was screwed up in refactoring to only apply to 'normal'
modules.

Misc code cleanup, mostly whitespace preferences, removing unused imports, plus a few fixes here and there.
