Patch review request (enabling backends to initiate a clean shutdown)

[Timothy Arceri <t_arceri yahoo com au>]

Hi Guys, 

 I
would like to request a review of my patch for enabling backends to
initiate a clean shutdown
https://bugzilla.gnome.org/show_bug.cgi?id=511802
 My
patch is based off the initial one created by Carlos
Garcia Campos in 2008, and I believe addresses the concerns with
his patch at that time.
 My
patch adds support for the cdda and sfpt backends. I have tested the
cdda backend, and are awaiting feedback on sftp tests from upstream
https://bugs.launchpad.net/gvfs/+bug/377322
 If
my patch is accepted it should be fairly easy to add support to more
backends. 

 This
should help fix bugs such as:
 https://bugzilla.gnome.org/show_bug.cgi?id=325979
 https://bugzilla.gnome.org/show_bug.cgi?id=515217 

As
well as other similar bugs in other backends once it has been added
to those backends.

Thanksfor your time,
Timothy Arceri
