Running ansible --version now outputs git information when the
repo lives in .git in the root of the ansible source (coping with the case
where the git info is elsewhere is left as an exercise).

This uses gitpython where installed, otherwise it interrogates the files
in the .git directory to get the same information.

The gitpython path could be removed, but then people might ask 'why did
you do it like this when gitpython exists'

Abstract how to look up user password to be more flexible

Fix error handling when switching versions

Protect all selinux calls with try/except

This adds user_password() to abstract how the user's password is looked
up.  If spwd is not available, this will read the shadow file for the
user's shadow entry.  This will then facilitate idempotent password
changes on hosts without spwd.

Add 'polite' YAML syntax validation and hinting

git module used to check stderr for the string 'error' after calling
switch_version().  This changes that to just look at the return code to
determine whether the command failed.  If the rc is not zero, the git
module will call fail_json().

The problem is that git checkout will summarize the commit message,
such as:

    HEAD is now at ea38409... removing artificial error

When the string 'error' is the commit message, this check will
erroneously think the command failed.

This also removes the method switchLocalBranch() since it is no longer
used.

login_unix_socket option for mysql modules

whitespace + remove deprecated YAML parser (migration script lives in examples/scripts and warning was added
in 0.6 release)

Fix some subtle behavior of how the get_url module chains into the file module, plus blend the results of daisy chain
operations in the correct order, so the file module results overlay the original module results, not the other way
around (which keeps any failure msg's intact)

Add encoding lines to python modules such that they can take unicode options if they are fed them, since the
AnsibleModule stuff no longer base64 encodes for simplicity and speed reasons.

remove the tab I found

- add a check for repoquery so we can abort politely

- make the results output a bit more readable
- fix up where repoquery is looked for so it is easier to change

Fixed a Bug in the service module "state changed" recognition
