[Qemu-devel] [PATCH v2 3/7] qga: move w32 service handling out of run_agent()

[Bishara AbuHattoum <bishara@daynix.com>]

From: Michael Roth <mdroth@linux.vnet.ibm.com>

Eventually we want a w32 service to be able to restart the qga main
loop from within service_main(). To allow for this we move service
handling out of run_agent() such that service_main() calls
run_agent() instead of the reverse.
