Spice opens many FDs to handle different channels (display, usb, sound,
etc.). For remote SSH URIs, this means we launch multiple SSH proceses.
We do so by forking off the process, and when SSH has successfully
authenticated, the data starts flowing.
If using spice + remote SSH w/o SSH keys, you need to put your data
into ssh askpass. askpass wants to own the display for security reasons.
When all the channel requests start coming in, we were launching multiple
ssh processes one after another. This upset askpass and generally
caused havoc in the app.
Add some infrastructure to serialize launching ssh processes. We only
launch the next ssh process if spice/vnc have conclusively connected
or errored out the connection. This makes connection a bit slower
for the non-askpass ssh case (about 1.5 seconds), but will ignore
avoid this oft reported problem.
This adds initial UI for managing snapshots: list, run/revert, delete,
add, and redefining (for changing <description>) supported, but currently
only for internal snapshots. The UI is mostly in its final form except for
some bells and whistles.
The real remaining question is what do we want to advertise and support.
Internal (qcow2) snapshots are by far the simplest to manage, very
mature, and already have the semantics we want.
However most recent libvirt and qemu work has been to facilitate
external snapshots, which are more extensible and can be performed
live, and with qemu-ga coordination for extra safety. However
they make things much harder for virt-manager at the moment.
Until we have a plan, this work should be considered experimental
and not be relied upon.
If an idle handler raises an exception, it isn't unregistered and loops
forever. This is a regression from previous pygobject and pygtk:

Work around this for now with our own wrappers.
Was originally added with hopes for being used in an ovirt related
product, but was more or less a code dump, and the author has been
allocated to other things. He confirmed it's okay to remove.
That, and it's currently broken, and we've had approximately 0 user
feedback since it was committed.
Despite being a known quantity, autotools is so overkill for our needs,
so let's drop it and replace it with a much simpler and easy to customize
system.
