[libvirt] [PATCH 4/5] qemu: support starting persistent domain paused

[Eric Blake]

Match earlier change for qemu pause support with virDomainCreateXML.

* src/qemu/qemu_driver.c (qemudDomainObjStart): Add parameter; all
callers changed.
(qemudDomainStartWithFlags): Implement flag support.
---

Question: should qemudDomainObjStart take an 'unsigned int flags'
instead of 'bool start_paused', in case we want to support further
flags in the future?
