Upon successful upload of a volume, the target volume and storage pool were not updated to reflect any changes as a result of the upload. Make use of the existing stream close callback mechanism to force a backend pool refresh to occur in a separate thread once the stream closes. The separate thread should avoid potential deadlocks if the refresh needed to wait on some event from the event loop which is used to perform the stream callback.

Update since v1 - as discussed in original posting, use virThreadCreate to generate a thread to handle the refresh callback:
http://www.redhat.com/archives/libvir-list/2014-July/msg01395.html
Avoid the Free callback function and have the thread do the memory free as long as thread creation was successful. Thus a couple of changes to function names were appropriate.
Understood that this can wait for 1.2.8 - figured to get it ready to go
NOTE: Still used pool refresh, since I found that without this patch applied a pool-dumpxml displayed the same allocation/available before and after the upload, so that data is not refreshed for each call as was my concern over using refreshVol vs. refreshPool
