6d19c14c28 lvmdbus: Fix deprecated warnings for GObject use
While running on F24 a number of warnings were being emitted from using the
deprecated GObject instead of GLib.  Tested on python 3.4 and 3.5.

3f5629302a lvmdbus: Fix exception during exception handling
Python 3.5 in F24 was throwing the following exception:

Traceback (most recent call last):
  File "/usr/lib/python3.5/site-packages/lvmdbusd/main.py", line 73, in process_request
    req.run_cmd()
  File "/usr/lib/python3.5/site-packages/lvmdbusd/request.py", line 73, in run_cmd
    self.register_error(-1, st)
  File "/usr/lib/python3.5/site-packages/lvmdbusd/request.py", line 123, in register_error
    self._reg_ending(None, error_rc, error)
  File "/usr/lib/python3.5/site-packages/lvmdbusd/request.py", line 115, in _reg_ending
    self.cb_error(self._rc_error)
  File "/usr/lib64/python3.5/site-packages/dbus/service.py", line 669, in <lambda>
    keywords[error_callback] = lambda exception: _method_reply_error(connection, message, exception)
  File "/usr/lib64/python3.5/site-packages/dbus/service.py", line 293, in _method_reply_error
    exception))
  File "/usr/lib64/python3.5/traceback.py", line 136, in format_exception_only
    return list(TracebackException(etype, value, None).format_exception_only())
  File "/usr/lib64/python3.5/traceback.py", line 442, in __init__
    if (exc_value and exc_value.__cause__ is not None
AttributeError: 'str' object has no attribute '__cause__'

This was caused because we were calling the dbus error callback with a
string instead of an actual exception.  On python 3.4 this was apparently
OK, but not with 3.5.  Corrected to pass the exception to error callback.
Change tested on both python 3.4 and 3.5.

f1bc68beb4 lvmdbusd: Reduce unnecessary state refreshes
When we use udev or have lvm call back into the dbus service when a
change occurs, even if that change originated from the dbus service
we end up refreshing the state of the system twice which is not
needed or wanted.  This change handles this case by removing any
pending refreshes in the worker queue if the state of the system
was just updated.

export LVMDBUSD_SESSION=True to run on the session bus instead
of the system bus so that we can run the unit test without

70d0b210e1 lvmdbusd: background.py, fix stdout parse error
It appears that the output of lvconvert --merge can vary some.  The code
was blowing up as it was trying to parse a line of stdout to retrieve the
% complete, but the line did not have the needed format and an execption
was thrown.  The uncaught exception caused the background thread to exit
without updating the job object, which caused the client to hang forever
waiting.  Added a default exception handler to prevent unhandled execptions
causing hangs and removed the parameter skip_first_line as it's no longer
needed.  The code checks to see if the line can be parsed before doing so.
