5cf51fb2f7 dbus: log_debug needs qualifier
Adding qualifier makes the only unqualified log_debug occurence
consistent with other uses in the same file.

Other possible ways to fix this:

- using `from .utils import log_debug`
- moving the line below `from . import utils` line

e53454d6de lvmdbusd: Use work queue for queries too
We need to place query operations in the queue to prevent the case where
a client knows of something before the service does.  For example if a
client creates a PV/VG/LV outside of the dbus API and then immediately
tries to lookup and use that resource in the lvm dbus service it should
be present.  By placing the queries in the work queue any previous
refresh operation will complete before we process the query.

99806ec7ec lvmdbusd: Place Manager.UseLvmShell request on queue
We need to acquire a lock which can block us which in turn causes
the dbus request handling to block as well.  Place the request on
the work queue instead.

fa444906bb lvmdbusd: Use one thread to fetch state updates
In preparation to have more than one thread issuing commands to lvm
at the same time we need to serialize updates to the dbus state and
retrieving the global lvm state.  To achieve this we have one thread
handling this with a thread safe queue taking and coalescing requests.

2bb09b4015 lvmdbusd: Be more explicit on return values
The python dbus library tries to make best on what the dbus type is based on
python data type.  Some times it gets this wrong, so we will be explicit.

4902034c89 lvmdbusd: Use udev until ExternalEvent occurs
The normal mode of operation will be to monitor for udev events until an
ExternalEvent occurs.  In that case the service will disable monitoring
for udev events and use ExternalEvent exclusively.

Note: User specifies --udev the service will always monitor udev regardless
if ExternalEvent is being called too.
