Add return code and error output to raw module

Since we use 'raw' heavily on equipment where 'command' and 'shell' are not (yet) working (and python may need to be installed first using raw) these improvements are necessary in order to write more complex scripts (with return code handling and separated stdout/stderr).

This change includes the following changes:

 - exec_command() now returns the return code of the command
 - _low_level_exec_command() now returns a dict, including 'rc', 'stdout' and 'stderr'
 - all users of the above interfaces have been improved to make use of the above changes
 - all connection plugins have been modified to return rc and stderr
 - fix the newline problem (stdout and stderr would have excess newlines)

In a future commit I intend to add assertions or error handling code to verify the return code in those places where it wasn't done. Since only the output was available, the return code was ignored, even though we expect them to be 0.

Allow to change executable (shell/interpreter) when using raw

This patch adds an optional 'executable=' option to the raw command line to override the default shell (/bin/sh), much like the shell module does.

syslog.openlog does not cope with unicode first argument

It seems that os.path.basename(__file__) can return a unicode
string. In this case syslog.openlog fails. Forcing the result
to a string causes the resulting error to go away.
git module documentation: removed incorrect use of term 'remote branch' (should just be 'remote').
Update path_dwim() to return absolute path

If path_dwim() is provided a relative path to a file, it will now return an
absolute path of the playbook directory + the relative file path.

Update path_dwim() to return absolute path
Expands path on file operations

Path might have to be expanded on some operations. It seems that path
containing '~' are not.
Using os.path.expanduser in appropriate places solves the problem, but
this might be required in many other places.
