differnt from the current user. This should enable overrides for user in
.ssh/config w/o breaking any current functionality.

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.
This change avoids the "tcgetattr: Invalid argument" error by making sure the ssh we start does have a proper pseudo-tty.
We could also check whether our current terminal is a proper terminal (by doing a tcgetattr ourselves) but I don't think this adds anything.
This closes#1662 (if all use-cases have been tested: sudo, passwd)
