9a67fc4d6e storagepool: Don't double invoke 'refresh' when events are present
We need to tweak refresh() handling to work similar to the shared
XML and status caching in libvirtobject.py: when the user manually
invokes the refresh() operation, and storage events are set up,
we just invoke the refresh() but let the event loop handle
refreshing the cache.

This fixes a backtrace when invoking a manual refresh via the
host details dialog

6d587c40bb storagepool: Don't refresh newly arriving pools
If they show up while a connection is 'active', it means they were
just defined/created, and thus a pool refresh is likely redundant

d0ffd954cd connection: Unify initial object refresh handling
Have libvirtobjects advertise a routine specifically for initial setup,
and emit a signal when it's complete. Then dispatch the associated conn
signal on demand as the objects are initialized. This should avoid a
whole class of ordering issues, and is easier to follow IMO.

38738d9fa6 connection: Don't close VM dialog on rename
Rework things a bit to simplify everything we pass around.

The specific bug fix is making sure we update the object list in place,
otherwise the event loop detects it as the VM being deleted and closes
the details window.

d1c22b3b2c storagepool: Don't default to refreshing volume list
This needlessly hits the network too much. The places where it's
important to have up to date info will either manually call pool
refresh, or give the user an refresh button.

aefd4c4824 connection: Use name instead of uuid for object keys
And clean up the API mess while we are at it. Treat the key as an opaque
value that users shouldn't depend on.

Besides the improved code clarity and API layout, this will help diagnose
'key error' issues, since we'll see an object name instead of UUID which
is hard to trace back.

5e9e444dec connection: Do non-VM polling on demand
The goal here is to reduce the amount of tick() polling that we do by default.
For things like pools, networks, and interfaces, the constant polling is
not very helpful and causes CPU churn and slowness for remote connections.

Switch to a more on demand style. Pages that want new information for
these objects now request a priority tick that only refreshes the info
we want.

This isn't perfect, but neither was the previous solution in the face of
things like XML updates behind our back. The real solution here is libvirt
event support across the board.

ead31139b0 virtManager: Emit state change signals from objects
This is a step towards supporting listAll*() API and domain events.

We still proxy these signals through vmmConnection so that we don't

be2d9ddcb4 Add base conn object and bump minimum libvirt version to 0.6.0
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.
