This base connection object will be used to simplify the API in various
places, reduce libvirt API calls, and better share code between virtinst
and virt-manager. For now it just centralizes connection opening.
This also exposed various places where our handling for older libvirt
was busted, so raise our minimum host version to 0.6.0, the first
version that supports threaded client requests.
When LXC guest was shut down while its console was open, virt-manager
got stuck in a loop due to the fact that the readable event was not
properly removed from the callback. Mimicking the behavior from
libvirt's tolls/console.c file, this patch properly closes the console
in case stream.recv() returns empty string.

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.
